Optic neuritis is inflammation of the optic nerve, the nerve that carries the visual signal from the eye to the brain. The condition may cause sudden, reduced vision in the affected eye(s). While the cause of optic neuritis is unknown, it has been associated with autoimmune diseases, infections, multiple sclerosis, drug toxicity and deficiency of vitamin B-12. Vision often returns to normal within 2-3 weeks without treatment. In some cases, corticosteroids are given to speed recovery. If known, the underlying cause should be treated.
What is (are) Optic neuritis ?
The diagnosis of optic neuritis is usually based on clinical findings and ophthalmologic examination. A careful history, including information about recent illness, fever, or immunizations is helpful. An eye exam should be conducted with assessment of visual acuity, pupil reactions, color vision and peripheral vision. The optic nerve should be examined with ophthalmoscopy for inflammation and swelling. Additional tests may include MRI of the brain, spinal tap and blood tests.

Aicardi-Goutieres syndrome is an inherited condition that mainly affects the brain, immune system, and skin. It is characterized by early-onset severe brain dysfunction (encephalopathy) that usually results in severe intellectual and physical disability. Additional symptoms may include epilepsy, painful, itchy skin lesion (chilblains), vision problems, and joint stiffness. Symptoms usually progress over several months before the disease course stabilizes. There are six different types of Aicardi-Goutieres syndrome, which are distinguished by the gene that causes the condition: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, and ADAR genes. Most cases are inherited in an autosomal recessive pattern, although rare autosomal dominant cases have been reported. Treatment is symptomatic and supportive.

Milroy disease is a lymphatic disease that causes swelling (lymphedema) in the lower legs and feet. Lymphedema is usually present at birth or develops in infancy. It typically occurs on both sides of the body and can worsen over time. Other symptoms may include accumulation of fluid in the scrotum in males (hydrocele), upslanting toenails, deep creases in the toes, wart-like growths, prominent leg veins, and/or cellulitis. Milroy disease is sometimes caused by changes (mutations) in the FLT4 gene and is inherited in an autosomal dominant manner. In many cases, the cause remains unknown. Treatment may include lymphedema therapy to improve function and alleviate symptoms.
What is (are) Milroy disease ?
The most common symptom of Milroy disease is build-up of fluids (lymphedema) in the lower limbs, which is usually present from birth or before birth. However, the degree and distribution of swelling varies among affected people. It sometimes progresses, but may improve in some cases. Other signs and symptoms may include hydrocele and/or urethral abnormalities in males; prominent veins; upslanting toenails; papillomatosis (development of wart-like growths); and cellulitis. Cellulitis may cause additional swelling. The Human Phenotype Ontology provides the following list of signs and symptoms for Milroy disease. 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 Milroy disease ?
Milroy disease is inherited in an autosomal dominant manner. This means that having one changed (mutated) copy of the responsible gene in each cell is enough to cause symptoms of the condition. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated copy of the gene. Most people with Milroy disease have an affected parent, but some cases are due to new mutations that occur for the first time in the affected person. About 10-15% of people with a mutation in the responsible gene do not develop features of the condition. This phenomenon is called reduced penetrance.
Is Milroy disease inherited ?
Yes. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for Milroy disease. The intended audience for the GTR is health care providers and researchers. People with questions about genetic testing should speak with a health care provider or genetics professional. If a mutation in the responsible gene has been identified in a family, genetic testing for at-risk relatives may identify those who may benefit from treatment early in the disease course. Prenatal testing for pregnancies at increased risk may also be available.
How to diagnose Milroy disease ?
There is currently no cure for Milroy disease. Management is typically conservative and usually successful in most people. Management of lymphedema should be guided by a lymphedema therapist. Some improvement is usually possible with the use of properly fitted compression hosiery or bandaging and well fitting, supportive shoes. Good skin care is essential. These measures may improve the cosmetic appearance of the affected areas, decrease their size, and reduce the risk of complications. Decongestive physiotherapy, which combines compression bandaging, manual lymphatic drainage (a specialized massage technique), exercise, breathing exercises, dietary measures and skin care, has become the standard of care for primary lymphedema. People with recurrent cellulitis may benefit from prophylactic antibiotics. Surgical intervention is considered a last option when other medical management fails. When possible, people with Milroy disease should avoid: wounds to swollen areas (because of their reduced resistance to infection) long periods of immobility prolonged standing elevation of the affected limb certain medications (particularly calcium channel-blocking drugs that can cause increased leg swelling in some people)

Fibromuscular dysplasia (FMD) is the abnormal development or growth of cells in the walls of arteries that can cause the vessels to narrow or bulge. The carotid arteries, which pass through the neck and supply blood to the brain, are commonly affected. Arteries within the brain and kidneys can also be affected. Narrowing and enlarging of arteries can block or reduce blood flow to the brain, causing a stroke. Some patients experience no symptoms of the disease while others may have high blood pressure, dizziness or vertigo, chronic headache, intracranial aneurysm, ringing in the ears, weakness or numbness in the face, neck pain, or changes in vision. FMD is most often seen in people age 25 to 50 years and affects women more often than men. More than one family member may be affected by the disease. The cause of FMD is unknown. Treatment is based on the arteries affected and the progression and severity of the disease.

What are the symptoms of Fibromuscular dysplasia ?
The cause of fibromuscular dysplasia is unknown. It is likely that there are many factors that contribute to the development of this condition. These factors may include blood vessel abnormalities, tobacco use, hormone levels, and genetic predispositions. Approximately 28 percent of affected individuals have more than one artery with fibromuscular dysplasia. It is not known why some people develop this condition in more than one artery.

Human T-cell leukemia virus, type 2 (HTLV-2) is a retroviral infection that affect the T cells (a type of white blood cell). Although this virus generally causes no signs or symptoms, scientists suspect that some affected people may later develop neurological problems and/or chronic lung infections. HTLV-2 is spread by blood transfusions, sexual contact and sharing needles. It can also be spread from mother to child during birth or breast-feeding. There is no cure or treatment for HTLV-2 and it is considered a lifelong condition; however, most infected people remain asymptomatic (show no symptoms) throughout life.

Human T-cell leukemia virus, type 2 (HTLV-2) generally causes no signs or symptoms. Although HTLV-2 has not been definitively linked with any specific health problems, scientists suspect that some affected people may later develop neurological problems such as:[7046] Sensory neuropathies (conditions that affect the nerves that provide feeling) Gait abnormalities Bladder dysfunction Mild cognitive impairment Motor abnormalities (loss of or limited muscle control or movement, or limited mobility) Erectile dysfunction Although evidence is limited, there may also be a link between HTLV-2 and chronic lung infections (i. e. pneumonia and bronchitis), arthritis, asthma, and dermatitis.
What are the symptoms of Human T-cell leukemia virus type 2 ?
Human T-cell leukemia virus, type 2 (HTLV-2) occurs when a person is infected by the human T-cell leukemia retrovirus. HTLV-2 is spread by blood transfusions, sexual contact and sharing needles. It can also be spread from mother to child during birth or breast-feeding. It is unclear why some people with HTLV-2 may develop neurological problems and other medical conditions, while others remain asymptomatic (show no signs or symptoms) their entire lives.
What causes Human T-cell leukemia virus type 2 ?
Human T-cell leukemia virus, type 2 (HTLV-2) is usually diagnosed based on blood tests that detect antibodies to the virus. However, HTLV-2 is often never suspected or diagnosed since most people never develop any signs or symptoms of the infection. Diagnosis may occur during screening for blood donation, testing performed due to a family history of the infection, or a work-up for an HTLV-2-associated medical problems.
How to diagnose Human T-cell leukemia virus type 2 ?
No cure or treatment exists for human T-cell leukemia virus, type 2 (HTLV-2). Management is focused on early detection and preventing the spread of HTLV-2 to others. Screening blood doners, promoting safe sex and discouraging needle sharing can decrease the number of new infections. Mother-to-child transmission can be reduced by screening pregnant women so infected mothers can avoid breastfeeding.

Situs inversus is a condition in which the arrangement of the internal organs is a mirror image of normal anatomy. It can occur alone (isolated, with no other abnormalities or conditions) or it can occur as part of a syndrome with various other defects. Congenital heart defects are present in about 5-10% of affected people. The underlying cause and genetics of situs inversus are complex. Familial cases have been reported.
What is (are) Situs inversus ?
In isolated situs inversus (occurring alone with no other abnormalities), there is a complete mirror image transposition of the thoracic (chest) and abdominal organs, and anterior-posterior (front-back) symmetry is normal. Many affected people have no associated health issues when the condition is isolated. When situs inversus occurs in association with other conditions such as Kartagener syndrome or primary ciliary dyskinesia, additional signs and symptoms relating to these conditions will be present.
What are the symptoms of Situs inversus ?
The genetics of situs inversus is complex. Several familial cases have been reported in which the inheritance has been described as either autosomal recessive (most commonly), autosomal dominant, or X-linked. The condition appears to be genetically heterogeneous, meaning that different genetic factors or genes may cause the condition among different people or families. If situs inversus is associated with another underlying syndrome or condition, the inheritance pattern may be the same as that of the underlying condition. People with questions about genetic risks to themselves or family members are encouraged to speak with a genetics professional.
Is Situs inversus inherited ?
A thorough physical examination, followed by radiographic imaging of the chest and abdomen and electrocardiography, identify most cases of situs inversus. The main diagnostic challenge in affected people is the non-traditional presence of referred pain (pain felt in a different location than its source).
How to diagnose Situs inversus ?
In isolated situs inversus, no treatment may be necessary. When situs inversus is associated with another condition, treatment may depend on the associated condition and the signs and symptoms present in the affected person. Knowing that a person has situs inversus is important for diagnosing medical problems and preventing surgical mishaps that can result from the failure to recognize reversed anatomy. For example, in a person with situs inversus, appendicitis causes pain in the left lower abdomen instead of the right lower abdomen. Wearing medical identification can help ensure proper treatment in an emergency medical situation.

Systemic capillary leak syndrome is a condition in which fluid and proteins leak out of tiny blood vessels and flow into surrounding tissues, resulting in dangerously low blood pressure. Attacks frequently last for several days and require emergency care. Most cases of capillary leak occur randomly in previously healthy adults. Treatment involves preventing attacks using medications which may decrease capillary leakage and interfere with hormones that may cause future leakage. Once an attack is underway, treatment is aimed at controlling blood pressure to maintain blood flow to vital organs and prevention of swelling due to fluid accumulation. Capillary leak syndrome may lead to multiple organ failure, shock and even death.

Pyle disease is a bone disorder characterized by genu valgum (knock knees), Erlenmeyer flask deformity (where there is relative constriction of the diaphysis or shaft of the bone and flaring of the metaphysis or end of the bone), widening of the ribs and clavicles (collarbones), platyspondyly (flattening of the bones of the spine) and cortical thinning. Only about 30 cases have been reported in the literature. Cranial involvement is minimal with some showing mild hyperostosis (excessive new bone formation ) of the skull base and thickening of the frontal and occipital bones. Pyle disease is passed through families in an autosomal recessive manner.

What are the symptoms of Pyle disease ?
Pyle disease in inherited in an autosomal recessive manner, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they often dont have any signs and symptoms of the condition. Some carriers (obligate heterozygotes) of Pyle disease show minor skeletal changes.

Granulomatous amebic encephalitis is a life-threatening infection of the brain caused by the free-living amoebae Acanthamoeba spp. , Balamuthia mandrillaris and Sappinia pedata. Acanthamoeba species, are commonly found in lakes, swimming pools, tap water, and heating and air conditioning units. The disease affects immunocompromised peple and is very serious. Symptoms include mental status changes, loss of coordination, fever, muscular weakness or partial paralysis affecting one side of the body, double vision, sensitivity to light and other neurologic problems. The diagnosis is difficult and is often made at advanced stages. Tests useful in the diagnosis include brain scans, biopsies, or spinal taps and in disseminated disease, biopsy of the involved sites and testing by the laboratory experts. Early diagnosis is important for the prognosis. No single drug is effective; hence multiple antibiotics are needed for successful treatment. A combination of surgical and medical interventions involving multiple specialty experts is required to prevent death and morbidity in survivors.

Calciphylaxis is a disease in which blood vessels (veins and arteries) become blocked by a build-up of calcium in the walls of the vessels, preventing blood from flowing to the skin or internal organs. The lack of blood flow (ischemia) damages healthy tissue and causes it to die (necrosis). The most obvious and frequent symptom of calciphylaxis is damage to the skin, as ulcers can develop and become infected easily. Calciphylaxis can also affect fat tissue, internal organs, and skeletal muscle, causing infections, pain, and organ failure. These symptoms are often irreversible, and many individuals with calciphylaxis may not survive more than a few months after they are diagnosed due to infection that spreads throughout the body (sepsis), or organ failure. The exact cause of calciphylaxis is unknown. Treatments may include medications to reduce pain, antibiotics to treat infections, and various approaches to preventing the development or worsening of this condition.

The Human Phenotype Ontology provides the following list of signs and symptoms for Osteopoikilosis and dacryocystitis. 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) Increased bone mineral density 90% Lacrimation abnormality 90% Autosomal dominant inheritance - Dacrocystitis - Osteopoikilosis - 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.

Pityriasis lichenoides et varioliformis acuta (PLEVA) is the acute form of a skin condition called pityriasis lichenoides. Affected people generally develop a few to more than one hundred scaling papules which may become filled with blood and/or pus or erode into crusted red-brown spots. PLEVA generally resolves on its own within a few weeks to a few months; however, some people experience episodes of the condition on and off for years. Although PLEVA is diagnosed in people of all ages, it most commonly affects children and young adults. The exact underlying cause is unknown, but some scientists suspect that it may occur due to an exaggerated immune response or an overproduction of certain white blood cells (lymphoproliferative disorder). If treatment is necessary, recommended therapies may include oral antibiotic, sun exposure, topical steroids, immunomodulators (medications used to help regulate or normalize the immune system), phototherapy and/or systemic steroids.
What is (are) Pityriasis lichenoides et varioliformis acuta ?
Pityriasis lichenoides et varioliformis acuta (PLEVA) is the acute form of a skin condition called pityriasis lichenoides. It is characterized by the sudden onset of red patches that quickly develop into scaling papules. These papules may become filled with blood and/or pus or erode into crusted red-brown spots. People may also experience burning and itching of the affected area. Scarring and/or temporary discoloration of the skin may be present after the lesions have healed. Although PLEVA can affect almost any part of the body, it most commonly develops on the trunk and/or limbs (arms/legs). Affected people may have a few to more than one hundred papules. The skin abnormalities generally resolve without treatment in a few weeks to a few months; however, some people experience episodes of the condition on and off for years. Aside from the skin findings, most affected people do not experience any additional signs and symptoms. However, some may experience fever, headaches, joint pain and swelling of nearby lymph nodes. Febrile Ulceronecrotic Mucha-Haberman Disease is a rare and severe variant of PLEVA that is associated with unique signs and symptoms. For more information on this condition, please click here.
What are the symptoms of Pityriasis lichenoides et varioliformis acuta ?
The exact underlying cause of pityriasis lichenoides et varioliformis acuta (PLEVA) is unknown. Some scientists suspect that it may occur due to an exaggerated immune response or hypersensitivity to an infection. Some of the infections that have been associated with PLEVA include: Toxoplasma gondii Epstein-Barr virus HIV Cytomegalovirus Parvovirus (fifth disease) Staphylococcus aureus Group A beta-haemolytic streptococci Others scientists think the condition may be a benign lymphoproliferative disorder. These conditions are characterized by an overproduction of certain white blood cells (lymphocytes) which can result in tissue and organ damage.
What causes Pityriasis lichenoides et varioliformis acuta ?
A diagnosis of pityriasis lichenoides et varioliformis acuta is often suspected based on characteristic signs and symptoms. A skin biopsy can be used to confirm the diagnosis. Additional laboratory testing may be ordered to investigate a possible cause such as an associated infection.
How to diagnose Pityriasis lichenoides et varioliformis acuta ?
Pityriasis lichenoides et varioliformis acuta (PLEVA) often resolves on its own within several weeks to several months. Depending on the severity of the condition and the symptoms present, treatment may not be necessary. If treatment is indicated, there are many different therapies that have been used to treat PLEVA with varying degrees of success. These include: Oral antibiotics Sun exposure Topical steroids Immunomodulators (medications used to help regulate or normalize the immune system) Phototherapy Systemic steroids Unfortunately, PLEVA may not always respond to treatment and relapses often occur when treatment is discontinued.

Ankylosing spondylitis (AS) is a type of chronic, inflammatory arthritis that mainly affects the spine. It usually begins with inflammation of the joints between the pelvic bones and spine, gradually spreading to the joints between the vertebrae. Signs and symptoms usually begin in adolescence or early adulthood and may include back pain and stiffness. Back movement gradually becomes more limited as the vertebrae fuse together. The condition may also affect the shoulders; ribs; hips; knees; and feet; as well as the eyes; bowel; and very rarely, the heart and lungs. AS is likely caused by a combination of genetic and environmental factors; variations in several genes are thought to affect the risk to develop AS. In most cases, treatment involves exercise and medications to relieve pain and inflammation.
What is (are) Ankylosing spondylitis ?
Ankylosing spondylitis (AS) primarily affects the spine, but may affect other parts of the body too. Signs and symptoms usually begin in adolescence or early adulthood and include back pain and stiffness. Back movement gradually becomes more limited over time as the vertebrae fuse together. Many affected people have mild back pain that comes and goes; others have severe, chronic pain. In very severe cases, the rib cage may become stiffened, making it difficult to breathe deeply. In some people, the condition involves other areas of the body, such as the shoulders, hips, knees, and/or the small joints of the hands and feet. It may affect various places where tendons and ligaments attach to the bones. Sometimes it can affect other organs including the eyes, and very rarely, the heart and lungs. Episodes of eye inflammation may cause eye pain and increased sensitivity to light (photophobia). Neurological complications of AS may include an inability to control urination and bowel movements (incontinence), and the absence of normal reflexes in the ankles due to pressure on the lower portion of the spinal cord (cauda equina). The Human Phenotype Ontology provides the following list of signs and symptoms for Ankylosing spondylitis.

What are the symptoms of Ankylosing spondylitis ?
Although ankylosing spondylitis (AS) can affect more than one person in a family, it is not a purely genetic disease. While genes seem to play a role, the exact cause of AS is not known. It is considered to be multifactorial, which means that multiple genetic and environmental factors likely interact to affect a persons risk to develop AS. Most of these factors have not been identified. Inheriting a genetic variation that has been associated with AS does not mean a person will develop AS. Currently, it is not possible to predict the exact likelihood that the children of an affected person will develop the disease. You can find more information about the genetics of AS from Genetics Home Reference, the U. S National Library of Medicines Web site for consumer information about genetic conditions and the genes or chromosomes related to those conditions.
Is Ankylosing spondylitis inherited ?
The main goal of treatment for people with ankylosing spondylitis (AS) is to maximize long-term quality of life. This may involve easing symptoms of pain and stiffness; retaining function; preventing complications (such as contractures); and minimizing the effects of associated conditions. Education, exercise, and medications are all very important in managing AS. An exercise program is recommended for all affected people, and some may need individual physical therapy. Affected people are encouraged to speak with their health care provider before instituting any changes to an exercise regime. Video demonstrations of exercises tailored for ankylosing spondylitis are available for viewing through the National Ankylosing Spondylitis Society in the UK. Medications may include nonsteroidal anti-inflammatory drugs (NSAIDs); pain relievers; sulfasalazine; and anti-tumor necrosis factor drugs. Steroid injections may be helpful for some people. Most people dont need surgery, but it may be indicated when there is severe, persistent pain or severe limitation in mobility and quality of life. Smoking creates additional problems for people with AS, so affected people who smoke should quit.

Hepatoblastoma is a rare malignant (cancerous) tumor of the liver that usually occurs in the first 3 years of life. In early stages of the condition, there may be no concerning signs or symptoms. As the tumor gets larger, affected children may experience a painful, abdominal lump; swelling of the abdomen; unexplained weight loss; loss of appetite; and/or nausea and vomiting. The exact underlying cause of hepatoblastoma is poorly understood. Risk factors for the tumor include prematurity with a very low birth weight, early exposure to hepatitis B infection, biliary atresia, and several different genetic conditions (i. e. Beckwith-Wiedemann syndrome, familial adenomatous polyposis, Aicardi syndrome, Glycogen storage disease, and Simpson-Golabi-Behmel syndrome). Treatment varies based on the severity of the condition but may include a combination of surgery, watchful waiting, chemotherapy, and/or radiation therapy.

Achondrogenesis is a group of severe disorders that are present from birth and affect the development of cartilage and bone. Infants with achondrogenesis usually have a small body, short arms and legs, and other skeletal abnormalities that cause life-threatening complications. There are at least three forms of achondrogenesis, type 1A, type 1B and type 2, which are distinguished by signs and symptoms, pattern of inheritance, and the results of imaging studies such as x-rays (radiology), tissue analysis (histology), and genetic testing. Type 1A and 1B achondrogenesis are both inherited in an autosomal recessive pattern. Type 1B may be caused by mutations in the SLC26A2 gene. Type 2 achondrogenesis is inherited in an autosomal dominant pattern and is caused by new (de novo) mutations in the COL2A1 gene.

Congenital hypothyroidism is a condition that affects infants from birth and results from a partial or complete loss of thyroid function (hypothyroidism). The thyroid gland makes hormones that play an important role in regulating growth, brain development, and metabolism in the body. Congenital hypothyroidism occurs when the thyroid gland fails to develop or function properly. In the United States and many other countries, all newborns are tested for congenital hypothyroidism as part of newborn screening. If untreated, congenital hypothyroidism can lead to intellectual disability and abnormal growth. If treatment begins in the first month after birth, infants usually develop normally. Treatment involves medication to replace the missing thyroid hormones, such as levothyroxine. Most cases of congenital hypothyroidism occur in people with no history of the disorder in their family. About 15-20% of cases are due to an underlying gene mutation. Rarely, congenital hypothyroidism can be a symptom included in a larger genetic disorder called a syndrome.

Chromosome 8q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 8. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 8q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person.

Distal chromosome 18q deletion syndrome is a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material at the end of the long arm (q) of chromosome 18. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with distal chromosome 18q deletion syndrome include developmental delay, intellectual disability, behavioral problems and distinctive facial features. Chromosome testing of both parents can provide more information on whether or not the deletion was inherited. In most cases, parents do not have any chromosomal anomaly. However, sometimes one parent is found to have a balanced translocation, where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an affected child with a chromosomal anomaly like a deletion. Treatment is based on the signs and symptoms present in each person. This page is meant to provide general information about distal 18q deletions. You can contact GARD if you have questions about a specific deletion on chromosome 18. To learn more about chromosomal anomalies please visit our GARD webpage on FAQs about Chromosome Disorders.

Adenoameloblastoma is a lesion that is often found in the upper jaw. Some consider it a non-cancerous tumor, others a hamartoma (tumor-like growth) or cyst. Often, an early sign of the lesion is painless swelling. These tumors are rarely found outside of the jaw.
What is (are) Adenoameloblastoma ?
Currently the cause of adenoameloblastoma is not well understood. It may be associated with an interruption in tooth development. These legions tend to occur more commonly in young people (around 20 year-old), and most often in young women. Adenoameloblastomas in the front upper jaw are often associated with an impacted tooth.
What causes Adenoameloblastoma ?
Treatment may require the removal of the legion as well as the surrounding tissues. Once the treatment is complete, recurrence of the legion is very rare.

Autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) is an uncommon, inherited form of epilepsy. Signs and symptoms include seizures that usually occur at night during sleep. The seizures that occur in people with ADNFLE can last from a few seconds to a few minutes, and can vary from causing simple arousal from sleep to severe, dramatic muscle spasm events. Some people with ADNFLE also have seizures during the day. Some episodes may be misdiagnosed as nightmares, night terrors, or panic attacks. The onset of ADNFLE ranges from infancy to adulthood, but most cases begin in childhood. Episodes tend to become milder and less frequent with age. ADNFLE is inherited in an autosomal dominant manner and may be caused by a mutation in any of several genes. In many cases, the genetic cause remains unknown. Seizures can usually be controlled with antiseizure medications.
What is (are) Autosomal dominant nocturnal frontal lobe epilepsy ?
The seizures that occur in people with autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) usually occur at night while sleeping, but some affected people also have seizures during the day. The seizures tend to occur in clusters, with each one lasting from a few seconds to a few minutes. In some people, seizures are mild and only cause a person to wake from sleep. In others, severe episodes can cause sudden, dramatic muscle spasms, wandering around, and/or crying out or making other sounds. Episodes of seizures tend to become less frequent and more mild as an affected person ages. Some people with ADNFLE experience aura, which may cause neurological symptoms such as tingling, shivering, a sense of fear, dizziness, and/or a feeling of falling or being pushed. Feelings of breathlessness, hyperventilation, and choking have also been reported. Most people with ADNFLE are intellectually normal. Psychiatric disorders, behavioral problems and intellectual disability have been described in some people with ADNFLE, but it is unclear if these features are directly related to the condition.

What are the symptoms of Autosomal dominant nocturnal frontal lobe epilepsy ?
The diagnosis of autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) is made on clinical grounds. The key to diagnosis is a detailed history from the affected person, as well as witnesses. Sometimes video-EEG monitoring is necessary. The features that are suggestive of a diagnosis of ADNFLE are: clusters of seizures with a frontal semiology seizures that occur predominantly during sleep normal clinical neurologic exam normal intellect (although reduced intellect, cognitive deficits, or psychiatric disorders may occur) normal findings on neuroimaging ictal EEG (recorded during a seizure) that may be normal or obscured by movement of the cables or electrodes interictal EEG (recorded in between seizures) that shows infrequent epileptiform discharges (distinctive patterns resembling those that occur in people with epilepsy) the presence of the same disorder in other family members, with evidence of autosomal dominant inheritance The diagnosis can be established in a person with the above features, combined with a positive family history and/or genetic testing that detects a mutation in one of the genes known to cause ADNFLE. People who are concerned they may be having seizures or other neurological signs or symptoms should be evaluated by a neurologist.

Pili torti is a rare hair condition characterized by fragile hair. In pili torti hair has a flattened shaft with clusters of narrow twists at irregular intervals. Some cases may be inherited in autosomal dominant or autosomal recessive patterns, while others are acquired. In the inherited form, symptoms tend to be present from early childhood. It can occur alone or as part of other diseases like ectodermal dysplasias, Menke disease, Bjornstand syndrome, or Bazex syndrome. Acquired cases of pili torti may be associated with anorexia nervosa, malnutrition, oral retinoid treatment, or inflammatory scalp conditions (e. g. , cutaneous lupus erythematousus). If pili torti is detected, it is necessary to investigate possible neurological disorders, hearing loss, and defects in the hair, nails, sweat glands and teeth. There is no specific treatment for this condition, but it may improve spontaneously after puberty. Click here to visit Medscape and view an image of a child with pili torti.

In acquired pili torti, treatment involves stopping the exposure to the causative agent (e. g. , to oral retinoids) or condition (e. g. , improving diet). There is no specific treatment for the inherited form of pili torti. It may improve spontaneously after puberty. If pili torti is detected, further evaluation to investigate possible neurological disorders, problems with hair, teeth or nails (ectodermal disturbances) and hearing loss is mandatory. It is generally recommended that people with pili torti try to avoid trauma to the hair. Suggestions include, sleeping on a satin pillowcase, avoiding excessive grooming, braiding, heat treatments, dying and coloring, reducing exposure to sunlight (wear a hat), using gentle shampoos diluted in warm water, adding conditioner to freshly washed hair, avoiding use of a hair dryer (or using it on cool setting), and avoiding oral retinoids (e. g. , isotretinoin, acitretin) if possible. Some individuals with pili torti choose to wear a wig.

Chromosome 19p deletion is a chromosome abnormality that occurs when there is a missing (deleted) copy of genetic material on the short arm (p) of chromosome 19. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 19p deletion include developmental delay, intellectual disability, behavioral problems and distinctive facial features. Chromosome testing of both parents can provide more information on whether or not the deletion was inherited. In most cases, parents do not have any chromosomal anomaly. However, sometimes one parent is found to have a balanced translocation, where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an affected child with a chromosomal anomaly like a deletion. Treatment is based on the signs and symptoms present in each person. This page is meant to provide general information about 19p deletions. You can contact GARD if you have questions about a specific deletion on chromosome 19. To learn more about chromosomal anomalies please visit our GARD webpage on FAQs about Chromosome Disorders.

Brachydactyly type B is a very rare genetic condition characterized by disproportionately short fingers and toes. The ends of the second and fifth fingers are usually underdeveloped with complete absence of the fingernails. The thumb bones are always intact but are frequently flattened and/or split. The feet are usually similarly affected, but less severely. Other features that may be present include webbed fingers (syndactyly) and fusion of the joints (symphalangism) and bones in the hands and feet. Only a few cases have been reported in the literature. This condition is caused by mutations in the ROR2 gene. Most cases have been shown to be inherited in an autosomal dominant fashion.

Konigsmark Knox Hussels syndrome is an inherited condition that causes both hearing and vision loss. This condition is characterized by late-onset progressive sensorineural deafness and progressive optic atrophy, which results in mildly reduced visual acuity. Some affected individuals can develop ophthalmoplegia (paralysis of the muscles that control eye movements), ptosis, ataxia, and non-specific myopathy in middle age. This condition is caused by a particular mutation in the OPA1 gene and is inerited in an autosomal dominant fashion.

Konigsmark Knox Hussels syndrome is caused by a particular mutation in the OPA1 gene. In most cases, this condition is caused by a mutation that replaces the amino acid arginine with the amino acid histidine at position 445 in the OPA1 protein. This is written as Arg445His or R445H. It is unclear why the R445H mutation causes both hearing and vision loss in affected individuals.

Melioidosis is an infectious disease caused by the bacteria Burkholderia pseudomallei that are commonly found in the soil and water. Melioidosis is a rare disease in the United States, but it is common in tropical or subtropical areas of the world, including Southeast Asia, Africa, and Australia. The signs and symptoms of the disease can vary greatly and may mimic those of tuberculosis or common forms of pneumonia. Signs and symptoms may include pain or swelling, fever, abscess, cough, high fever, headache, trouble breathing, and more. Although healthy people can also experience signs and symptoms of the disease, people with certain conditions like diabetes, liver disease, kidney disease, lung disease, thalassemia, cancer, or certain autoimmune diseases are more severely affected. Diagnosis is made by collecting blood, sputum, urine, or pus samples and growing the bacteria. Current treatment is divided into two stages: an intravenous (IV) antibiotic stage and oral antibiotic maintenance stage to prevent recurrence.

Toxocariasis is a parasitic condition caused by the larvae of two species of Toxocara roundworms: Toxocara canis (from dogs) and Toxocara cati (from cats). Many people who are infected with Toxocara never develop any signs or symptoms of the condition. In those who do become sick, symptoms may present as: Ocular Toxocariasis - when the larvae infect the eye and cause vision loss, eye inflammation, and/or damage to the retina. Visceral Toxocariasis - when the larvae infect various organs of the body (i. e. the liver or the central nervous system) and cause fever, fatigue, coughing, wheezing, and/or abdominal pain. Toxocariasis is generally spread through dirt that has been contaminated with animal feces that contain infectious Toxocara eggs. Young children and owners of dogs and cats have a higher chance of becoming infected. Visceral toxocariasis is treated with antiparasitic medications. Treatment of ocular toxocariasis is more difficult and usually consists of measures to prevent progressive damage to the eye.

Isolated ectopia lentis (IEL) is a genetic disorder that affects the positioning of the lens in the eyes. In individuals with IEL, the lens in one or both of the eyes is off-center. Symptoms of IOL usually present in childhood and may include vision problems such as nearsightedness (myopia), blurred vision (astigmatism), clouding of the lenses (cataracts), and increased pressure in the eyes (glaucoma). In some individuals, IEL can progress to retinal detachment (tearing of the back lining of the eye). IEL is caused by mutations in either the FBN1 or ADAMTSL4 gene. When caused by a mutation in the FBN1 gene, IEL is inherited in an autosomal dominant manner. When caused by a mutation in the ADAMTSL4 gene, IEL is inherited in an autosomal recessive manner. The primary goal of treatment is preventing amblyopia (lazy eye) through early correction of astigmatism. Surgical intervention including lensectomy (removal of the lens) may be considered in cases where vision is significantly affected.

Spinocerebellar ataxia autosomal recessive 7, also called SCAR7, is a slowly progressive hereditary form of spinocerebellar ataxia. Symptoms of SCAR7 can include difficulty walking and writing, speech difficulties (dysarthria), limb ataxia, and a decrease in the size of a region of the brain called the cerebellum (cerebellar atrophy). Of the few reported cases in the literature, some patients also had eye involvement that included nystagmus (in voluntary eye movements) and saccadic pursuit eye movements. Out of 5 affected siblings examined in a large Dutch family, 2 became wheelchair-dependent late in life. The severity of the symptoms varies from mild to severe. SCAR7 is caused by mutations in the TPP1 gene and is inherited in an autosomal recessive manner.

Waardenburg syndrome type 2 is an inherited condition that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes. About 50 percent of those with Waardenburg syndrome type 2 have a hearing impairment or are deaf. Type 2 is one the most common forms of Waardenburg syndrome, along with type 1. Waardenburg syndrome type 2 may be caused by mutations in the MITF and SNAI2 genes. This condition is usually inherited in an autosomal dominant fashion, but can sometimes be inherited as an autosomal recessive trait.
What is (are) Waardenburg syndrome type 2 ?
In general, Waardenburg syndrome is characterized by varying degrees of hearing loss and changes in skin and hair color (pigmentation). Those with Waardenburg syndrome type 2, do not have a wide space between the inner corners of their eyes or other facial abnormalities. Most have a hearing impairment or are deaf and also have heterochromia of the iris (two different colored eyes). Other features of Waardenburg syndrome, including white forelock, premature graying of the hair, and irregular depigmentation of the skin, are less common in this type.

Subtypes of Waardenburg syndrome type 2 are determined by the suspected genetic cause of the condition in a family. In some subtypes, the genetic cause is a known gene. In other subtypes, the general location (locus) of the genetic cause has been identified, but the specific gene is not yet known. There are five different subtypes: Type 2A is caused by a change (mutation) in the MITF gene on chromosome 3 Type 2B is associated with a locus on chromosome 1 Type 2C is associated with a locus on chromosome 8 Type 2D is caused by mutations is the SNAI2 gene on chromosome 8 Type 2E is caused by mutations in the SOX10 gene on chromosome 22 Because subtypes are defined by the underlying genetic cause, they are not diagnosed by physical features identified during a physical exam. Physical features may be used to distinguish between types of Waardenburg syndrome, such as Type 1 or Type 2, but do not help identify a specific subtype.

Gliomatosis cerebri is a type of brain cancer. It is a variant form of glioblastoma multiforme. It is characterized by scattered and widespread tumor cells that can cause the cerebrum, cerebellum, or brain stem to enlarge. Signs and symptoms may include personality changes, memory disturbance, headache, hemiparesis, and seizures. Because this tumor is so diffuse it can be challenging to treat and the prognosis for people with gliomatosis cerebri is generally poor.

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.

Autoimmune gastrointestinal dysmotility (AGID) is a rare form of autoimmune autonomic neuropathy that can occur either due to an idiopathic cause or a paraneoplastic cause. Idiopathic forms of AGID are a manifestation of autoimmune autonomic neuropathy that affects the digestive nervous system. The signs and symptoms of AGID may include achalasia,gastroparesis, hypertrophic pyloric stenosis, intestinal pseudo-obstruction, megacolon and anal spasm. Treatment options for AGID includes symptom relief, treatment of any underlying neoplasm if necessary, immunotherapy and supportive treatment. Nutrition and hydration therapy as well as management of abdominal pain are important supportive treatment measures.

Notalgia paresthetica is a common chronic, localized itch, that usually affects patches of skin on the upper back. Occasionally be more widespread and involve other parts of the back, the shoulders and upper chest. People feel both the sensation of an itch and paresthesia (a sensation of tingling, pricking, or numbness of the skin). There are no signs on the skin except for signs of chronic scratching and rubbing. Amyloid deposits (a collection of a specific type of protein) may be found in skin biopsies, but this is thought to be a secondary event. The cause of the itch in notalgia paresthetica may be due to the compression of spinal nerves by bones or muscles as the nerves emerge through the vertebrae to the back muscles. Sometimes degenerative changes in the area of the vertebrae that innervate the affected back muscles can be seen, but not always. Symptoms of notalgia paresthetica may respond to topical capsaicin treatment.

While this condition may be difficult to treat, typical neuralgia therapies are often employed with moderate success. Effective measures may include: Cooling lotions as required (camphor and menthol) Capsaicin cream - this depletes nerve endings of their chemical transmitters Local anaesthetic creams Amitriptyline tablets at night Transcutaneous electrical nerve stimulation (TENS) Gabapentin Oxcarbazepine Botulinum toxin Phototherapy Exercise Additional information about treatment of notalgia paresthetica can be accessed by clicking here. You can find relevant journal articles on treatment of notalgia paresthetica through a service called PubMed, a searchable database of medical literature. Information on finding an article and its title, authors, and publishing details is listed here. Some articles are available as a complete document, while information on other studies is available as a summary abstract.

Maternally inherited diabetes and deafness (MIDD) is a form of diabetes that is often accompanied by hearing loss, especially of high tones. The diabetes in MIDD is characterized by high blood sugar levels (hyperglycemia) resulting from a shortage of the hormone insulin, which regulates the amount of sugar in the blood. MIDD is caused by mutations in the MT-TL1, MT-TK, or MT-TE gene. These genes are found in mitochondrial DNA, which is part of cellular structures called mitochondria. Although most DNA is packaged in chromosomes within the cell nucleus, mitochondria also have a small amount of their own DNA (known as mitochondrial DNA or mtDNA). Because the genes involved with MIDD are found in mitochondrial DNA, this condition is inherited in a mitochondrial pattern, which is also known as maternal inheritance. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, only females pass mitochondrial conditions to their children. Mitochondrial disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass mitochondrial traits to their children.
