Cold agglutinin disease is a rare type of autoimmune hemolytic anemia in which the bodys immune system mistakenly attacks and destroys its own red blood cells. When affected peoples blood is exposed to cold temperatures (32 to 50 F), certain proteins that normally attack bacteria (IgM antibodies) attach themselves to red blood cells and bind them together into clumps (agglutination). The antibodies then activate other components of the blood, which eventually causes red blood cells to be prematurely destroyed. As the number or red blood cells drop, affected people typically experience anemia, which may be associated with pallor, weakness, fatigue, irritability, headaches, and/or dizziness. Other signs and symptoms of cold agglutinin disease vary, but may include: Painful fingers and toes with purplish discoloration Abnormal behavior Amenorrhea Gastrointestinal issues Dark urine Enlargement of the spleen Jaundice Heart failure Shock The Human Phenotype Ontology provides the following list of signs and symptoms for Cold agglutinin disease. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Arthralgia 90% Autoimmunity 90% Hemolytic anemia 90% Muscle weakness 90% Pallor 90% Abnormality of urine homeostasis 7. 5% Diarrhea 7. 5% Hepatomegaly 7. 5% Lymphadenopathy 7. 5% Migraine 7. 5% Nausea and vomiting 7. 5% Splenomegaly 7. 5% The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
What are the symptoms of Cold agglutinin disease ?
Cold agglutinin disease is typically classified as primary (unknown cause) or secondary (caused by an underlying condition). Secondary cold agglutinin disease may be associated with: Bacterial Infections such as mycoplasma, Legionnaires disease, syphilis, listeriosis, or E. Coli Viral infections such Epstein-Barr virus, cytomegalovirus, mumps, varicella, rubella, adenovirus, HIV, influenza, or hepatitis C Parasitic infections such as malaria or trypanosomiasis Other autoimmune diseases such as systemic lupus erythematosus Certain types of cancers such as lymphoma, chronic lymphocytic leukemia, Waldenstrm macroglobulinemia, multiple myeloma, and Kaposi sarcoma
What causes Cold agglutinin disease ?
Cold agglutinin disease is not an inherited condition. It is designated as either primary (unknown cause) or secondary (associated with or caused by another condition). In some cases, cold agglutinin may be multifactorial which means that multiple environmental factors and genes likely interact to predispose a person to developing the condition. However, to our knowledge, no disease-causing genes have been identified and no familial cases have been reported.
Is Cold agglutinin disease inherited ?
A diagnosis of cold agglutinin disease may be made after several types of tests are performed by a health care provider. In some cases, the diagnosis is first suspected by chance if a routine complete blood count (CBC) detects abnormal clumping (agglutination) of the red blood cells. In most cases, the diagnosis is based on evidence of hemolytic anemia (from symptoms and/or blood tests). A person may also be physically examined for spleen or liver enlargement. An antiglobulin test (called the Coombs test) may be performed to determine the presence of a specific type of antibody. In people with cold agglutinin disease, the Coombs test is almost always positive for immunoglobulin M (IgM). Detailed information about the various tests used to make a diagnosis of cold agglutinin disease is available on Medscape References Web site. Please click on the link to access this resource.
How to diagnose Cold agglutinin disease ?
The treatment of cold agglutinin disease depends on many factors including the severity of the condition, the signs and symptoms present in each person, and the underlying cause. For example, in those affected by secondary cold agglutinin disease, it is important to diagnose and treat the underlying condition which may include certain types of cancer; bacterial, viral, or parasitic infections; and/or other autoimmune disease. People with few symptoms and/or mild anemia may not require any specific treatment. These cases are often managed by simply avoiding exposure to the cold. In severe cases, medical interventions may be necessary. Rituximab (an antibody that selectively reduces specific types of immune cells) may be recommended either alone or in combination with other medications for people with severe hemolysis. Plasmapheresis, which involves filtering blood to remove antibodies, and/or blood transfusions may be an option for temporary relief of severe symptoms. Other therapies exist; however, they have been used with variable success. Medscape References Web site offers more specific information about these alternative treatments.

Oculodentodigital dysplasia is a condition that affects many parts of the body, particularly the eyes (oculo-), teeth (dento-), and fingers (digital). The condition is caused by mutations in the GJA1 gene. Most cases are inherited in an autosomal dominant pattern. Some cases are caused by a new mutation in the gene. A small number of cases follow an autosomal recessive pattern of inheritance. Management is multidisciplinary and based on specific symptoms. Early diagnosis is critical for prevention and treatment.
What is (are) Oculodentodigital dysplasia ?
Individuals with oculodentodigital dysplasia commonly have small eyes (microphthalmia) and other eye abnormalities that can lead to vision loss. They also frequently have tooth abnormalities, such as small or missing teeth, weak enamel, multiple cavities, and early tooth loss. Other common features of this condition include a thin nose and webbing of the skin (syndactyly) between the fourth and fifth fingers. Less common features of oculodentodigital dysplasia include sparse hair growth (hypotrichosis), brittle nails, an unusual curvature of the fingers (camptodactyly), syndactyly of the toes, small head size (microcephaly), and an opening in the roof of the mouth (cleft palate). Some affected individuals experience neurological problems such as a lack of bladder or bowel control, difficulty coordinating movements (ataxia), abnormal muscle stiffness (spasticity), hearing loss, and impaired speech (dysarthria). A few people with oculodentodigital dysplasia also have a skin condition called palmoplantar keratoderma. Palmoplantar keratoderma causes the skin on the palms and the soles of the feet to become thick, scaly, and calloused. Some features of oculodentodigital dysplasia are evident at birth, while others become apparent with age. The Human Phenotype Ontology provides the following list of signs and symptoms for Oculodentodigital dysplasia.

Merkel cell carcinoma (MCC) is a rare type of skin cancer that usually appears as a single, painless, lump on sun-exposed skin. It is typically red or violet in color. It is considered fast-growing and can spread quickly to surrounding tissues, nearby lymph nodes, or more distant parts of the body. Merkel cell polyomavirus has been detected in about 80% of the tumors tested. It is thought that this virus can cause somatic mutations leading to MCC when the immune system is weakened. Other risk factors for developing MCC include ultraviolet radiation and being over 50 years of age. Treatment should begin early and depends on the location and size of the cancer, and the extent to which it has spread.
What is (are) Merkel cell carcinoma ?
The exact underlying cause of Merkel cell carcinoma (MCC) is unknown, but several risk factors have been associated with the development of MCC. Having one or more risk factors does not mean that a person will develop MCC; most individuals with risk factors will not develop MCC. Risk factors include: -being over 50 years of age -having fair skin -having a history of extensive sun exposure (natural or artificial) -having chronic immune suppression, such as after organ transplantation or having HIV Researchers have also found that a virus called Merkel cell polyomavirus (MCPyV) is frequently involved in the development of MCC. MCPyV is found in about 80% of tumor cells tested. This virus is thought to alter the DNA in such a way that influences tumor development.
What causes Merkel cell carcinoma ?
To our knowledge, there currently is no evidence that Merkel cell carcinoma (MCC) is inherited. While DNA changes (mutations) found in the cells of MCC tumors can lead to MCC, these types of mutations are not inherited from a persons parents. They are referred to as somatic mutations and occur during a persons lifetime, often as random events. Sometimes, something in the environment can lead to a somatic mutation, such as long-term sun exposure or infection with the Merkel cell polyomavirus. These are known risk factors for developing MCC.

Cerulean cataracts are opaque areas that develop in the lens of the eye that often have a bluish or whitish color. They may be present at birth or develop in very early childhood, but may not be diagnosed until adulthood. They are usually bilateral and progressive. Infants can be asymptomatic, but may also be visually impaired from birth and develop nystagmus and amblyopia. In adulthood, the cataracts may progress, making lens removal necessary. Cerulean cataracts may be caused by mutations in several genes, including the CRYBB2, CRYGD, and MAF genes, and are inherited in an autosomal dominant manner. No treatment is known to prevent cerulean cataracts, but frequent evaluations and cataract surgery are typically required to prevent amblyopia as the opacities progress.

What are the symptoms of Cerulean cataract ?
No treatment is known to prevent cerulean cataracts, and there is currently no cure for the condition. Frequent eye evaluations and eventual cataract surgery are typically required to prevent amblyopia (vision loss) as the opacities progress. The symptoms of early cataracts may be improved with new eyeglasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. However, if these measures do not help, surgery is often the only effective treatment. Surgery involves removing the cloudy lens and replacing it with an artificial lens. Surgery is often considered when vision loss regularly interferes with everyday activities, such as driving, reading, or watching TV.

Multiple mitochondrial dysfunctions syndrome (MMDS) is a severe condition that affects the energy-producing structures of cells (called the mitochondria). Signs and symptoms of this condition generally develop early in life and may include encephalopathy, hypotonia (poor muscle tone), seizures, developmental delay, failure to thrive, lactic acidosis and a variety of other health problems. Due to the severity of the condition, most affected babies do not live past infancy. MMDS can be caused by changes (mutations) in the NFU1 gene or the BOLA3 gene. In these cases, the condition is inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person.

Glioma refers to a type of brain tumor that develops from the glial cells, which are specialized cells that surround and support neurons (nerve cells) in the brain. It is generally classified based on which type of glial cell is involved in the tumor: Astocytoma - tumors that develop from star-shaped glial cells called astrocytes Ependymomas - tumors that arise from ependymal cells that line the ventricles of the brain and the center of the spinal cord Oligodendrogliomas - tumors that affect the oligodendrocytes The symptoms of glioma vary by type but may include headaches; nausea and vomiting; confusion; personality changes; trouble with balance; vision problems; speech difficulties; and/or seizures. The exact underlying cause is unknown. In most cases, the tumor occurs sporadically in people with no family history of the condition. Treatment depends on many factors, including the type, size, stage and location of the tumor, but may include surgery, radiation therapy, chemotherapy and/or targeted therapy.

Bilateral frontal polymicrogyria is one of the rarest subtypes of polymicrogyria. It is a symmetric and bilateral form (in both brain hemispheres) that only involves the frontal lobes without including the area located behind the Sylvius fissure or the area located behind the Rolando sulcus. Some researchers classify the condition into two different forms: bilateral frontal polymicrogyria and the bilateral frontoparietal. Signs and symptoms included delayed motor and language milestones; spastic (stiffness) hemiparesis (weakness in one side of the body) or quadriparesis (weakness in all four limbs of the body); and mild to moderate intellectual disability. Seizures may also be present. The frontoparietal form is caused by changes (mutations) in the GPR56 gene but the cause for the frontal form of polymicrogyira is still not known. Treatment is based on the signs and symptoms present in each person.

Reticulohistiocytoma (RH) is a rare benign lesion of the soft tissue. It belongs to a group of disorders called non-Langerhans cell histiocytosis and is a type of reticulohistiocytosis, all of which are types of histiocytosis. Histiocytosis is a condition in which there is rapid production (proliferation) of histiocytes (immune cells) in the skin or soft tissues. The stimulus that causes the immune system to react in RH is currently not well understood. RH present as a yellow to reddish-brown smooth surfaced, firm nodule or lesion on the trunk and/or extremities of the body. Historically, RH has been found in young adults, with a slightly higher incidence in males. RH typically resolve spontaneously over a period of months to years, are not associated with systemic disease, and do not otherwise affect health. Treatment involves surgical removal of the lesion.

While it is known that reticulohistiocytoma (RH) develop due to a rapid production of immune cells (histiocytes) in the skin or soft tissues, the cause of this process is not currently known.
What causes Reticulohistiocytoma ?
The diagnosis of reticulohistiocytoma (RH) is made based on clinical presentation, histology, and immunohistochemistry profile. RH occur in isolation and are typically described as small, yellow to reddish-born nodules. The lesions usually are slightly elevated from the surrounding skin. Detailed information on histology of reticulohistiocytoma is available through DermNet NZ, an online resource about skin diseases developed by the New Zealand Dermatological Society Incorporated. There are several differential diagnoses for RH. It is important to distinguish RH from Rosai-Dorfman disease, juvenile xanthogranuloma, a variety of granulomatous conditions, and some malignant neoplasms, including histiocytic sarcoma, melanoma, and epithelioid sarcoma. Reticulohistiocytoma should also be distinguished from multicentric reticulohistiocytosis.
How to diagnose Reticulohistiocytoma ?
Reticulohistiocytoma (RH) typically resolve spontaneously over a period of months to years; however, surgical excision usually results in a cure.

For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

GRACILE syndrome is an inherited metabolic disease. GRACILE stands for growth retardation, aminoaciduria, cholestasis, iron overload, lactacidosis, and early death. Infants are very small at birth and quickly develop life-threatening complications. During the first days of life, infants will develop a buildup of lactic acid in the bloodstream (lactic acidosis) and amino acids in the urine (aminoaciduria). They will also have problems with the flow of bile from the liver (cholestasis) and too much iron in their blood. Affected individuals arent typically born with unique physical features. Although alkali therapy is used as treatment, about half of affected infants do not survive past the first days of life. Those that do survive this period generally do not live past 4 months despite receiving treatment. GRACILE syndrome is caused by a mutation in the BCS1L gene, and it is inherited in an autosomal recessive pattern. The BCS1L gene provides instructions needed by the mitochondria in cells to help produce energy.

Temporomandibular ankylosis is a condition that occurs when the temporomandibular joint (the joint that connects the jaw to the side of the head) becomes fused by bony or fibrous tissue. As a result, affected people may experience pain, speech impairment, and difficulty chewing and swallowing. It can interfere with nutrition, oral hygiene and the normal growth of the face and/or jaw. Although the condition can be diagnosed in people of all ages, it generally occurs during the first and second decades of life. Temporomandibular ankylosis is most commonly caused by trauma or infection; it may also be associated with certain conditions such as ankylosing spondylitis, rheumatoid arthritis, or psoriasis. The condition is typically treated surgically.

Late-onset familial Alzheimer disease is a form of familial Alzheimer disease that begins after age 65. In general, Alzheimer disease (AD) is a degenerative disease of the brain that causes gradual loss of memory, judgement and the ability to function socially. The exact underlying cause of late-onset familial AD is not completely understood; however, researchers suspect that it is a complex condition, which is likely associated with multiple susceptibility genes (such as the APOE e4 allele) in combination with environmental and lifestyle factors. Although complex conditions do tend to cluster in families, they do not follow a clear-cut pattern of inheritance. There is no cure for AD. Treatment is supportive and based on the signs and symptoms present in each person.

Tracheobronchomalacia (TBM) is a rare condition that occurs when the walls of the airway (specifically the trachea and bronchi) are weak. This can cause the airway to become narrow or collapse. There are two forms of TBM: a congenital form (called primary TBM) that typically develops during infancy or early childhood and an acquired form (called secondary TBM) that is usually seen in adults. Some affected people may initially have no signs or symptoms. However, the condition is typically progressive (becomes worse overtime) and most people will eventually develop characteristic features such as shortness of breath, cough, sputum retention (inability to clear mucus from the respiratory tract), and wheezing or stridor with breathing. Most cases of primary TBM are caused by genetic conditions that weaken the walls of the airway, while the secondary form often occurs incidentally due to trauma, chronic inflammation and/or prolonged compression of the airways. Treatment is generally only required in those who have signs and symptoms of the condition and may include stenting, surgical correction, continuous positive airway pressure (CPAP), and tracheostomy.

Tracheobronchomalacia (TBM) is a condition that occurs when the walls of the airway (specifically the trachea and bronchi) are weak. This can cause the airway to become narrow or collapse. There are two forms of TBM. Primary TBM (also called congenital TBM) typically develops during infancy or early childhood, while secondary TBM (also called acquired TBM) is usually seen in adults. Some affected people may initially have no signs or symptoms. However, the condition is typically progressive (becomes worse overtime) and many people will eventually develop characteristic features such as shortness of breath, cough, sputum retention (inability to clear mucus from the respiratory tract), and wheezing or stridor with breathing. Symptoms may become worse during periods of stress (i. e. illness), when reclining, or when forcing a cough. Infants and young children with TBM tend to have more frequent respiratory infections and delayed recovery from these illnesses.
What are the symptoms of Tracheobronchomalacia ?
The underlying cause of tracheobronchomalacia (TBM) varies by subtype. Most cases of primary TBM (also called congenital TBM) are caused by genetic conditions that weaken the walls of the airway (specifically the trachea and bronchi). For example, TBM has been reported in people with mucopolysaccharidoses (such as Hunter syndrome and Hurler syndrome), Ehlers-Danlos Syndrome, and a variety of chromosome abnormalities. Primary TBM can also be idiopathic (unknown cause) or associated with prematurity and certain birth defects (i. e. tracheoesophageal fistula). The secondary form (also called acquired TBM) is caused by the degeneration (break down) of cartilage that typically supports the airways. It is most commonly associated with: Certain medical procedures such as endotracheal intubation or tracheostomy Conditions that lead to chronic (persisting or progressing for a long period of time) inflammation such as relapsing polychondritis or chronic obstructive pulmonary disease (COPD) Cancers, tumors, or cysts that cause prolonged compression of the airway
What causes Tracheobronchomalacia ?
Primary tracheobronchomalacia (TBM) is often associated with certain genetic conditions. In some cases, an affected person inherits the condition from an affected parent. Other cases may result from new (de novo) gene mutations. These cases occur in people with no history of the disorder in their family. When TBM is part of a genetic condition, it can be passed on to future generations. Secondary TBM (also called acquired TBM) is not inherited. It generally occurs incidentally due to trauma, chronic inflammation and/or prolonged compression of the airways.
Is Tracheobronchomalacia inherited ?
A diagnosis of tracheobronchomalacia (TBM) may be suspected based on the presence of characteristic signs and symptoms or abnormal pulmonary function tests. Additional testing such as CT scan and bronchoscopy can then be performed to confirm the diagnosis and evaluate the severity of the condition. TBM is considered mild if the trachea narrows to 50% of its initial size while the affected person is breathing out, moderate if it narrows to 25%, and severe if the walls of the trachea touch.
How to diagnose Tracheobronchomalacia ?
Treatment is only medically necessary in people who have signs and symptoms of tracheobronchomalacia (TBM). Management of symptomatic TBM first involves identifying underlying conditions contributing to symptoms, such as chronic inflammation, compression, or injury. Initial treatment will target these underlying medical concerns. If symptoms persist, people with TBM may undergo pulmonary function tests or other assessments to help guide therapy choice and allow monitoring of the response to treatment. Treatment options may include: Silicone and/or long-term stenting Surgical correction Continuous positive airway pressure (CPAP) Tracheostomy (often used as a last resort as it can sometimes worsen TBM) We strongly recommend that you discuss your treatment options with a healthcare provider.

De Barsy syndrome is a rare genetic disorder characterized mainly by a prematurely aged-looking face (progeria); cloudy corneas; short stature; and intellectual disability. Affected individuals can have a wide variety of other signs and symptoms, including loose skin folds due to reduced elasticity (cutis laxa); poor muscle tone (hypotonia); movement disorders; and other features that involve the eyes, face, skin and nervous system. The genetic cause of the condition is not known in most cases, but it is inherited in an autosomal recessive manner. Treatment generally focuses on the signs and symptoms present in each individual and may include early eye surgery and physiotherapy to avoid contractures.

Septo-optic dysplasia is a disorder of early brain development. The signs and symptoms vary from person to person; however, underdevelopment (hypoplasia) of the optic nerve, abnormal formation of structures along the midline of the brain, and pituitary hypoplasia are the characteristic findings. Recurring seizures, delayed development, and abnormal movements may be present in some people with septo-optic dysplasia. Although the exact cause of septo-optic dysplasia is unknown, it is believed that both genetic and environmental factors play a role. Viruses, medications, and blood flow disruption have all been suggested as possible environmental causes. Thus far, three genes (HESX1, OTX2, and SOX2) have been associated with septo-optic dysplasia. Typically, people do not have a family history of septo-optic dysplasia. However, there have been a few cases in which multiple family members have been diagnosed. Familial cases may follow an autosomal recessive or autosomal dominant pattern of inheritance.
What is (are) Septo-optic dysplasia ?
Symptoms may include blindness in one or both eyes, pupil dilation in response to light, nystagmus (a rapid, involuntary to-and-fro movement of the eyes), inward and outward deviation of the eyes, hypotonia (low muscle tone), and hormonal problems leading to slow growth, unusually short stature, low blood sugar, genital abnormalities and problems with sexual development. Seizures may also occur. In a few cases, jaundice (prolonged yellow skin discoloration) may occur at birth. Intellectual problems vary in severity among individuals. While some children with septo-optic dysplasia have normal intelligence, others have learning disabilities and mental retardation. Most, however, are developmentally delayed due to vision impairment or neurological problems. The Human Phenotype Ontology provides the following list of signs and symptoms for Septo-optic dysplasia.

What are the symptoms of Septo-optic dysplasia ?
In most cases of septo-optic dysplasia, the cause of the disorder is unknown. Researchers suspect that a combination of genetic and environmental factors may play a role in causing this disorder. Proposed environmental risk factors include viral infections, specific medications, and a disruption in blood flow to certain areas of the brain during critical periods of development. At least three genes have been associated with septo-optic dysplasia, although mutations in these genes appear to be rare causes of this disorder. The three genes, HESX1, OTX2, and SOX2, all play important roles in embryonic development. In particular, they are essential for the formation of the eyes, the pituitary gland, and structures at the front of the brain (the forebrain) such as the optic nerves. Mutations in any of these genes disrupt the early development of these structures, which leads to the major features of septo-optic dysplasia. Researchers are looking for additional genetic changes that contribute to septo-optic dysplasia.

Dent disease type 1 is a kidney disease seen mostly in males. The most frequent sign of Dent disease is the presence of an abnormally large amount of protein in the urine (proteinuria). Other common signs of the disorder include excess calcium in the urine (hypercalciuria), calcium deposits in the kidney (nephrocalcinosis), and kidney stones (nephrolithiasis). In many males with Dent disease, progressive kidney problems lead to end-stage renal disease (ESRD) in early to mid-adulthood. ESRD ia a failure of kidney function that occurs when the kidneys are no longer able to effectively filter fluids and waste products from the body. Disease severity can vary even among members of the same family. Dent disease type 1 is inherited in an X-linked recessive manner. Approximately 60% of individuals with Dent disease 1 have a mutation in the CLCN5 gene which is located on the X chromosome. Due to random X-chromosome inactivation, some female carriers may manifest hypercalciuria and, rarely, proteinuria.

Hairy tongue is a condition in which the the central top portion of the tongue presents with an abnormal coloring. Although the abnormal coating is typically black in color, brown, yellow, and green discoloration has been described.
What is (are) Hairy tongue ?
The exact cause is unknown; however, smoking, alcohol, dehydration, use of antibiotics, low saliva production, trigeminal neuralgia, poor oral hygiene and cranial radiation therapy have shown to bring about hairy tongue.
What causes Hairy tongue ?
Although hairy tongue normally resolves on its own, patients are encouraged to avoid the factors that have been shown to bring about hairy tongue. Treatment usually involves gentle cleaning of the tongue with a soft toothbrush. Medication is rarely prescribed for hairy tongue; however, in severe cases, antifungals, retinoids or mouthwashes may be used. If treatment fails, the affected portion of the tongue called the papillae (finger-like projections) may be clipped or removed using techniques such as carbon dioxide laser burning or electrodesiccation (a procedure in which an electrical current is used to seal of the affected area).

X-linked creatine deficiency is a rare condition that primarily affects the brain. Signs and symptoms generally develop before age 2 and may include mild to severe intellectual disability; delayed speech development, behavioral problems (i. e. autistic features, hyperactivity), and seizures. Less commonly, affected people may have distinctive facial features, heart abnormalities, and gastrointestinal disorders. X-linked creatine deficiency is caused by changes (mutations) in the SLC6A8 gene and is inherited in an X-linked manner. Treatment with high doses of creatine monohydrate, L-arginine, and L-glycine has been used to treat some of the symptoms associated with X-linked creatine deficiency with variable success.

Bietti crystalline corneoretinal dystrophy is an inherited eye disease. Symptoms include crystals in the cornea (the clear covering of the eye); yellow, shiny deposits on the retina; and progressive atrophy of the retina, choriocapillaries and choroid (the back layers of the eye). This tends to lead to progressive night blindness and loss of visual acuity. Bietti crystalline corneoretinal dystrophy is caused by mutations in the CYP4V2 gene and inherited in an autosomal recessive fashion.

Schwannomatosis is a rare form of neurofibromatosis that is primarily characterized by multiple schwannomas (benign tumors of the nervous system) in the absence of bilateral (affecting both sides) vestibular schwannomas. Signs and symptoms of the condition vary based on the size, location and number of schwannomas but may include pain; numbness; tingling; and/or weakness in the fingers and toes. Inherited forms of the disorder account for only 15 percent of all cases. In some of these families, schwannomatosis is caused by changes (mutations) in the SMARCB1 or LZTR1 genes; in other cases, the exact underlying cause is unknown. When inherited, the condition is passed down in an autosomal dominant manner with highly variable expressivity and reduced penetrance. Treatment is based on the signs and symptoms present in each person but may include medications and/or surgery.
What is (are) Schwannomatosis ?
Signs and symptoms of the schwannomatosis often develop during adulthood between ages 25 and 30. Affected people generally have multiple schwannomas, which are benign tumors of the nervous system. In schwannomatosis, these tumors can grow along any nerve in the body, although they are less common on the vestibular nerve (vestibular schwannomas, also known as acoustic neuromas). People with vestibular schwannomas, especially those with tumors affecting the vestibular nerve on both sides of the head (bilateral), may have neurofibromatosis type 2 instead. The signs and symptoms associated with schwannomatosis vary based on the size and location of the schwannomas. The most common symptom is chronic pain, which can develop as a growing schwannoma presses on nerves or surrounding tissues. Some people may develop a mass if the schwannomas is located just beneath the skin. Others can experience neurological symptoms such as numbness; tingling; and/or weakness in the fingers and toes. The Human Phenotype Ontology provides the following list of signs and symptoms for Schwannomatosis. If the information is available, the table below includes how often the symptom is seen in people with this condition.

In these cases, the sign or symptom may be rare or common.
What are the symptoms of Schwannomatosis ?
Some cases of schwannomatosis are caused by changes (mutations) in the SMARCB1 or LZTR1 genes. SMARCB1 and LZTR1 are tumor suppressor genes, which means that they encode a protein that stops cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in these genes result in abnormal proteins that are unable to carry out their normal roles. This contributes to the development of the many different types of tumors found in schwannomatosis. When schwannomatosis is caused by a mutation in SMARCB1 or LZTR1, the affected person is typically born with one mutated copy of the gene in each cell and is, therefore, genetically predisposed to develop the tumors associated with the condition. For a tumor to form, two copies of the gene must be altered. The mutation in the second copy of the gene is considered a somatic mutation because it occurs during a persons lifetime and is not inherited. In affected people without a mutation in SMARCB1 or LZTR1, the underlying cause of the condition is unknown.
What causes Schwannomatosis ?
Approximately 15% percent of all schwannomatosis cases are thought to be inherited. In these cases, the condition is thought to be inherited in an autosomal dominant manner with highly variable expressivity and reduced penetrance. This means that a person only needs a change (mutation) in one copy of the responsible gene in each cell to have a genetic predisposition to the tumors associated with schwannomatosis. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. People with an inherited form of schwannomatosis have a 50% chance with each pregnancy of passing the condition on to the next generation.
Is Schwannomatosis inherited ?
A diagnosis of schwannomatosis is often suspected based on the presence of characteristic signs and symptoms, especially if there are other family members with the condition. Additional testing can then be ordered to further support the diagnosis and rule out other conditions with similar features (namely, neurofibromatosis type 2). This may include: Tumor pathology confirming that the growths are, in fact, schwannomas Imaging studies, such as an MRI examining the vestibular nerve. It is important to rule out the presence of bilateral (affecting both sides) vestibular schwannomas which would be suggestive of neurofibromatosis type 2 rather than schwannomatosis Genetic testing for a change (mutation) in the SMARCB1 or LZTR1 genes. Unfortunately, genetic testing is not informative in all people affected by schwannomatosis.
How to diagnose Schwannomatosis ?
Treatment for schwannomatosis is based on the signs and symptoms present in each person. For example, pain is one of the most common symptoms of the condition. Treatment with medications such as gabapentin or pregabalin and the use of short-acting opioids and/or nonsteroidal anti-inflammatories for pain can be successful for many patients. If pain cannot be managed with other means or if the schwannomas are causing other symptoms, they can be surgically removed. However this treatment is often used as a last resort because surgery may put patients at risk of further neurologic problems.

Singleton Merten syndrome is an extremely rare, multisystem disorder. The major characteristics are tooth abnormalities (dental dysplasia); calcifications in the aorta and certain valves of the heart (i. e. , aortic and mitral valves); and progressive thinning and loss of protein of the bones (osteoporosis), especially the upper and back portions of the skull. Other physical findings may include generalized muscle weakness; progressive muscle atrophy; growth delay; delays in motor development; skin conditions; and/or malformation of the hips and/or feet. It appears to occur sporadically (in individuals with no history of the condition in their family) but in some cases, autosomal dominant inheritance has been suggested. Treatment is typically directed toward the specific symptoms that are present in each individual.
What is (are) Singleton Merten syndrome ?
Singleton Merten syndrome is characterized by abnormalities of the teeth (dental dysplasia); abnormal accumulation of calcium deposits (calcifications) in the aorta and certain valves of the heart (i. e. , aortic and mitral valves); and/or progressive thinning and loss of protein of the bones (osteoporosis). Between the ages of four to 24 months, most affected infants experience generalized muscle weakness and loss or wasting away (atrophy) of muscle tissue. In approximately half of the reported cases, these symptoms begin after an episode of illness associated with a fever. Affected infants may also show delays in general physical development, possibly resulting in short stature or delays in the ability to coordinate muscles and perform certain tasks (motor development). Abnormalities affecting the teeth also occur at an early age in individuals with Singleton Merten syndrome. Affected infants may develop cavities and lose their primary teeth prematurely. Certain permanent teeth may not develop or may erupt late; those permanent teeth that do develop are usually malformed. In some cases, permanent teeth may also be lost prematurely. By late infancy or early childhood, affected individuals may experience symptoms associated with the progressive accumulation of calcium deposits (calcifications) in the aorta and on certain valves of the heart. The aorta arises from the lower pumping chamber of the heart (left ventricle) and supplies oxygen-rich blood to all the arteries of the body (excluding the pulmonary artery). In individuals with Singleton Merten Syndrome, calcifications form in the portion of the aorta nearest the heart (proximal thoracic aorta). The accumulation of calcium deposits is progressive and typically causes blockage and narrowing of the aorta (called calcific aortic stenosis), obstructing the flow of oxygenated blood. In some cases, abnormal calcium deposits may also develop around the valve on the left side of the heart (mitral valve calcification). As a result of calcification of these various structures, affected individuals may experience high blood pressure (hypertension); abnormal transmission of electrical impulses (conduction) that coordinate the activity of the heart muscle (heart block); abnormal contractions of the heart (systolic murmurs); and/or abnormal enlargement of the heart (cardiomegaly). By late adolescence, the heart may be unable to pump blood effectively, causing heart failure and leading to life-threatening complications. Infants with Singleton Merten syndrome may also experience abnormal thinning and weakness of the bones (osteoporosis). As a result, bones are frequently brittle and may fracture easily. Osteoporosis may occur in the skull and the long bones of the arms and legs, but is most prominent in the bones of the hands and fingers. Other findings associated with Singleton Merten syndrome may include malformations of the hips and feet that may occur due to muscle weakness; wearing away (erosion) of the bones in the tips of the fingers (terminal phalanges); and/or a chronic skin condition characterized by red, thick, scaly patches of skin (psoriasiform skin eruption). In some cases, affected individuals may have abnormal accumulation of pressure of the fluid of the eye (glaucoma) and/or abnormal sensitivity to light (photosensitivity). The Human Phenotype Ontology provides the following list of signs and symptoms for Singleton Merten syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What are the symptoms of Singleton Merten syndrome ?
The diagnosis of Singleton Merten syndrome may be suspected during infancy based upon the identification of characteristic physical findings (i. e. , muscle weakness, muscle atrophy, dental abnormalities, and skeletal changes). A diagnosis may be confirmed by a thorough clinical evaluation, a detailed patient history, and/or a variety of specialized tests. The identification of calcium deposits in the aorta, in association with the other findings described above, strongly suggests a diagnosis of Singleton Merten syndrome. X-ray tests may be used to confirm the presence and extent of calcifications in the aorta. Obstruction or narrowing (stenosis) of the heart valves, particularly the aortic and mitral valves, may be confirmed by cardiac catheterization. During this procedure, a small hollow tube (catheter) is inserted into a large vein and threaded through the blood vessels leading to the heart. This procedure allows physicians to determine the rate of blood flow through the heart and measure the pressure within the heart. X-ray studies may also be performed to confirm the presence and extent of osteoporosis. Osteoporosis may be suspected when bone fractures occur more frequently than usual. X-ray tests may also reveal abnormal widening of the hollow parts of the bones that contain soft fatty tissue (bone marrow cavities) within the bones of the hands and/or feet.
How to diagnose Singleton Merten syndrome ?
The treatment of Singleton Merten syndrome is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. Pediatricians, surgeons, specialists who diagnose and treat abnormalities of the heart (cardiologists), dental specialists, physical therapists, specialists who diagnose and treat conditions of the skin (dermatologists), and other health care professionals may need to systematically and comprehensively plan an affected childs treatment. Specific therapies for the treatment of Singleton Merten syndrome are symptomatic and supportive. Special services that may be beneficial to affected children may include special social support, physical therapy, and other medical, social, and/or vocational services. Genetic counseling would be of benefit for affected individuals and their families.

Pars planitis is a disease of the eye that is characterized by inflammation of the narrowed area (pars plana) between the colored part of the eye (iris) and the choroid. This may lead to blurred vision; dark, floating spots in the vision; and progressive vision loss. As the condition advances, cataracts, retinal detachment, or macular edema (fluid within the retina) may develop. Pars planitis most often affects young men and is generally not associated with any other disease or symptoms (idiopathic); however, it can be associated with other autoimmune conditions such as multiple sclerosis and sarcoidosis. Treatment typically includes corticosteroid drugs, immunosuppressive medications, and/or surgery.
What is (are) Pars planitis ?
Pars planitis is characterized by inflammation of the narrowed area (pars plana) between the colored part of the eye (iris) and the choroid. This may lead to blurred vision; dark, floating spots in the vision; and progressive vision loss. Approximately 80% of cases are bilateral (affecting both eyes), although one eye is typically more affected than the other. As the condition advances, cataracts, retinal detachment, or macular edema (fluid within the retina) may develop.
What are the symptoms of Pars planitis ?
The exact underlying cause of pars planitis is unknown. Scientists suspect that it is an autoimmune condition in which the bodys immune system mistakenly attacks healthy tissues (certain parts of the eyes, in this case). This is further supported by the fact that pars planitis is sometimes associated with other autoimmune conditions such as multiple sclerosis and sarcoidosis. Although most cases occur sporadically in people with no family history of the condition, pars planitis can rarely affect more than one family member. In these cases, there may be a genetic component; however, a disease-causing gene and specific inheritance pattern have not been identified.
What causes Pars planitis ?
Pars planitis is typically diagnosed based on a specialized eye examination. During the exam, the ophthalmologist will typically see clusters of white blood cells trapped within the eyeball that are called snowballs (or inflammatory exudate). If these clusters are located on the pars plana, they are known as snowbanks. Snowbanks are considered a hallmark sign of pars planitis. It is often recommended that people over age 25 with pars planitis have an MRI of their brain and spine to rule out multiple sclerosis.
How to diagnose Pars planitis ?
The first approach to treating pars planitis is corticosteroid eye drops or injections near the eye to control inflammation. Non-steroidal anti-inflammatory drugs (NSAIDs, including aspirin) or steroid medications (such as prednisone) can be taken by mouth. If these strategies are not successful, other medications may be given to reduce the bodys immune response (medications called immunosuppressants, such as methotrexate). If medications are not effective, surgery may be considered. Cryotherapy has been performed in affected people to remove eye tissue that has inflammation. Although this surgery has been shown to be effective in restoring clarity of vision, there are concerns that it may cause damage to other parts of the eye. Another surgery, known as vitrectomy, can be done to remove cloudy fluid (vitreous humor) from the eye.

Guillain-Barr syndrome is a rare disorder in which the bodys immune system attacks part of the peripheral nervous system. Symptoms include muscle weakness, numbness, and tingling sensations, which can increase in intensity until the muscles cannot be used at all. Usually Guillain-Barr syndrome occurs a few days or weeks after symptoms of a viral infection. Occasionally, surgery or vaccinations will trigger the syndrome. It remains unclear why only some people develop Guillain-Barr syndrome but there may be a genetic predisposition in some cases. Diagnosed patients should be admitted to a hospital for early treatment. There is no cure for Guillain-Barr syndrome, but treatments such as plasma exchange (plasmapheresis) and high dose immunoglobulins may reduce the severity and duration of symptoms. Recovery can take as little as a few days to as long as a few years. About 30% of those with Guillain-Barr syndrome have residual weakness. A small number may suffer a relapse many years after the initial attack.

Aberrant subclavian artery is a rare vascular anomaly that is present from birth. It usually causes no symptoms and is often discovered as an incidental finding (such as through a barium swallow or echocardiogram). Occasionally the anomaly causes swallowing difficulty (dysphagia lusoria). Swallowing symptoms in children may present as feeding difficulty and/or recurrent respiratory tract infection. When aberrant subclavian artery causes no symptoms, treatment is not needed. If the anomaly is causing significant symptoms, treatment may involve surgery. Children with symptomatic aberrant subclavian artery should be carefully evaluated for additional vascular and heart anomalies.

Porphyria cutanea tarda (PCT) is a form of porphyria that primarily affects the skin. People affected by this condition generally experience photosensitivity, which causes painful, blistering lesions to develop on sun-exposed areas of the skin (i. e. the hands and face). Skin in these areas may also be particularly fragile with blistering and/or peeling after minor trauma. In some cases, increased hair growth as well as darkening and thickening of the affected skin may occur. Liver abnormalities may develop in some people with the condition and PCT, in general, is associated with an increased risk of liver cirrhosis and liver cancer. In most cases, PCT is a complex or multifactorial condition that is likely associated with the effects of multiple genes in combination with lifestyle and environmental factors. For example, factors such as excess iron, alcohol, estrogens, smoking, chronic hepatitis C, HIV and mutations in the HFE gene (which is associated with the disease hemochromatosis) can all contribute to the development of PCT. Less commonly, PCT can run in families (called familial PCT). Familial PCT is caused by changes (mutations) in the UROD gene and is inherited in an autosomal dominant manner. Treatment may include regular phlebotomies (removing a prescribed amount of blood from a vein), certain medications, and/or removal of factors that may trigger the disease.

Fetal cystic hygroma is a congenital malformation of the lymphatic system. The lymphatic system is a network of vessels that maintains fluids in the blood, as well as transports fats and immune system cells. Cystic hygromas are single or multiple cysts found mostly in the neck region. In the fetus, a cystic hygroma can progress to hydrops (an excess amount of fluid in the body) and eventually lead to fetal death. Some cases resolve leading to webbed neck, edema (swelling), and a lymphangioma (a benign yellowish-tan tumor on the skin composed of swollen lymph vessels). In other instances, the hygroma can progress in size to become larger than the fetus. Cystic hygromas can be classified as septated (multiloculated) or nonseptated (simple). Cystic hygromas can occur as an isolated finding or in association with other birth defects as part of a syndrome (chromosomal abnormalities or syndromes caused by gene mutations). They may result from environmental factors (maternal virus infection or alcohol abuse during pregnancy), genetic factors, or unknown factors. The majority of prenatally diagnosed cystic hygromas are associated with Turner syndrome or other chromosomal abnormalities like trisomy 21. Isolated cystic hygroma can be inherited as an autosomal recessive disorder. Fetal cystic hygroma have being treated with OK-432, a lyophilized mixture of Group A Streptococcus pyogenes and benzyl penicillin, and with serial thoracocentesis plus paracentesis.

For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

Von Hippel-Lindau (VHL) disease is an inherited disorder characterized by the abnormal growth of both benign and cancerous tumors and cysts in many parts of the body. Tumors usually first appear in young adulthood. The types of tumors associated with VHL disease include hemangioblastomas (slow-growing tumors of the central nervous system); kidney cysts and clear cell renal cell carcinoma; pancreatic neuroendocrine tumors; pheochromocytomas (noncancerous tumors of the adrenal glands); and endolymphatic sac tumors. VHL disease is caused by a mutation in the VHL gene and is inherited in an autosomal dominant manner. Early detection and treatment of VHL disease is important, and usually involves surgical removal of tumors.
What is (are) Von Hippel-Lindau disease ?
Symptoms of Von Hippel-Lindau (VHL) disease vary among patients and depend on the size and location of the tumors. Hemangioblastomas that develop in the brain and spinal cord can cause headaches, vomiting, weakness, and a loss of muscle coordination (ataxia). Hemangioblastomas can also occur in the light-sensitive tissue that lines the back of the eye (the retina). These tumors, which are also called retinal angiomas, may cause vision loss. Pheochromocytomas affect the adrenal glands, which are small hormone-producing glands located on top of each kidney. These tumors often cause no symptoms, but in some cases they can produce an excess of hormones that cause dangerously high blood pressure. About 10 percent of people with VHL disease develop endolymphatic sac tumors, which are noncancerous tumors in the inner ear. These growths can cause hearing loss in one or both ears, as well as ringing in the ears (tinnitus) and problems with balance. Individuals with VHL disease are also at a higher risk than normal for certain types of cancer, especially kidney cancer. Renal cell carcinoma occurs in about 70% of individuals with VHL disease by age 60 and is the leading cause of mortality.

What are the symptoms of Von Hippel-Lindau disease ?
Von Hippel-Lindau (VHL) disease is caused by a mutation in the VHL gene. This gene is a tumor suppressor gene, which helps to control cell growth. Mutations in the VHL gene lead to a lack of regulation of cell growth and survival, allowing cells to grow and divide uncontrollably, forming the tumors that are associated with VHL disease.
What causes Von Hippel-Lindau disease ?
Mutations in the gene that causes VHL disease (the VHL gene) are inherited in an autosomal dominant manner. This means that having a mutation in only one copy of the VHL gene in each cell is enough to increase a persons risk of developing VHL disease. In most autosomal dominant conditions, having one mutated copy of the responsible gene is sufficient to cause the condition. However, in VHL disease, a mutation in the other copy of the gene must occur (during a persons lifetime) to trigger the development of VHL disease. For example, a person may inherit a mutated copy of the gene from a parent, but acquiring a second mutation in the other gene copy in a specific organ may trigger tumor development in that organ. Almost everyone who is born with one VHL mutation will eventually acquire a mutation in the second copy of the gene and develop VHL disease. In most cases, an affected person inherits the first mutated gene from an affected parent. However, in about 20% of cases, the mutation occurs for the first time in a person with no family history of the condition. This is called a de novo mutation. When a person with a mutation that can lead to VHL disease has children, each of their children has a 50% (1 in 2) chance to inherit that mutation.
Is Von Hippel-Lindau disease inherited ?
The diagnosis of von Hippel-Lindau (VHL) disease can be made based on specific clinical criteria (signs and symptoms), or when molecular genetic testing reveals a mutation in the VHL gene. Tests that may be used to establish a clinical diagnosis include: MRI of the brain and spinal cord fundoscopy ultrasound examination or MRI of the abdomen blood and urinary catecholamine metabolites.
How to diagnose Von Hippel-Lindau disease ?
Treatment for Von Hippel-Lindau (VHL) disease depends on the location and size of tumors. In general, the goal is to treat growths when they cause symptoms, but are still small so they dont cause permanent damage. Treatment usually involves surgical removal of tumors. Radiation therapy may be used in some cases. All people with VHL disease should be carefully followed by a physician or medical team familiar with the disorder.

Prinzmetals variant angina is characterized by recurrent episodes of chest pain that occur while an individual is at rest. This condition is a form of unstable angina because the episodes do not occur in a predictable pattern. Prinzmetals variant angina may occur spontaneously, or it may be caused by exposure to cold, emotional stress, alcohol withdrawal, or vasoconstricting medications. The symptoms of this condition usually respond to treatment. Individuals with Prinzmetals variant angina may have a higher risk for heart attack or arrhythmia.
What is (are) Prinzmetals variant angina ?
The main symptom of Prinzmetals variant angina is chest pain (angina) with the following characteristics: Occurs under the chest bone Described as squeezing, constricting, tightness, pressure, crushing Is usually severe and may radiate to the neck, jaw, shoulder, or arm Often occurs at rest Typically occurs at the same time each day, usually between midnight and 8am. Duration of pain is 5 to 30 minutes Pain is relieved by nitroglycerin Loss of consciousness
What are the symptoms of Prinzmetals variant angina ?
Prinzmetals variant angina is caused by coronary artery spasms. A coronary artery spasm is a temporary, abrupt, and focal (restricted to one location) contraction of the muscles in the wall of an artery in the heart. This spasm constricts the artery, slowing or stoping blood flow. A prolonged spasm can cause chest pain, or even a heart attack (myocardial infarction).
What causes Prinzmetals variant angina ?
The goal of treatment is to control chest pain and to prevent heart attack. Nitroglycerin or other nitrate medications may be prescribed to relieve chest pain. Calcium-channel blockers may be chronically needed. These medications widen the blood vessels to improve blood and oxygen flow. Medications may also include beta-blockers; however, in some individuals, beta-blockers may be harmful.
