What is (are) Parkes Weber syndrome ?

Parkes Weber syndrome (PWS) is a rare congenital condition causing an individual to have a large number of abnormal blood vessels. The main characteristics of PWS typically include a capillary malformation on the skin; hypertrophy (excessive growth) of the bone and soft tissue of the affected limb; and multiple arteriovenous fistulas (abnormal connections between arteries and veins) which can potentially lead to heart failure. Individuals may also have pain in the affected limb and a difference in size between the limbs. There has been evidence that some cases of PWS are caused by mutations in the RASA1 gene and are inherited in an autosomal dominant manner. Management typically depends on the presence and severity of symptoms and may include embolization or surgery in the affected limb.

What are the symptoms of Parkes Weber syndrome ?

What are the signs and symptoms of Parkes Weber syndrome? Parkes Weber syndrome is characterized by birthmarks caused by capillary malformations on the skin; hypertrophy (excessive growth) of the bone and soft tissue of the affected limb (which may lead to a difference in size between the affected and non-affected limb); and multiple arteriovenous fistulas (abnormal connections between arteries and veins). The Human Phenotype Ontology provides the following list of signs and symptoms for Parkes Weber syndrome. 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) Abnormality of coagulation 90% Abnormality of limb bone morphology 90% Lower limb asymmetry 90% Peripheral arteriovenous fistula 90% Skeletal muscle hypertrophy 90% Telangiectasia of the skin 90% Venous insufficiency 50% Congestive heart failure 7.5% Glaucoma 7.5% Hemiplegia/hemiparesis 7.5% Migraine 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 treatments for Parkes Weber syndrome ?

How might Parkes Weber syndrome be treated? For capillary malformations (such as port wine stains) that are of cosmetic concern, individuals may be referred to a dermatologist. For arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs), the risks and benefits of intervention (i,e, embolization versus surgery) may be considered, usually with input from a multi-disciplinary team (e.g., specialists in interventional radiology, neurosurgery, surgery, cardiology, and dermatology). For risks associated with heart failure, referral to a cardiologist may be warranted. Hypertrophy (overgrowth) of the limb and/or difference in size between limbs may be treated surgically by an orthopedist. Supportive care may include compression garments (tight-fitting pieces of clothing on the affected limb to reduce pain and swelling); these may also protect the limb from bumps and scrapes, which can cause bleeding. Heel inserts may be used if the legs are different lengths, which can aid in walking normally. Various pain medications and antibiotic medications may be prescribed as needed.

What is (are) Dihydropteridine reductase deficiency ?

Dihydropteridine reductase deficiency (DHPR) is a severe form of hyperphenylalaninemia (high levels of the amino acid phenylalanine in the blood) due to impaired renewal of a substance known as tetrahydrobiopterin (BH4). Tetrahydrobiopterin normally helps process several amino acids, including phenylalanine, and it is also involved in the production of neurotransmitters. If little or no tetrahydrobiopterin is available to help process phenylalanine, this amino acid can build up in the blood and other tissues and the levels of neurotransmitters (dopamine, serotonin) and folate in cerebrospinal fluid are also decreased. This results in neurological symptoms such as psychomotor delay, low muscle tone (hypotonia), seizures, abnormal movements, too much salivation, and swallowing difficulties. DHPR deficiency is caused by mutations in the QDPR gene. It is inherited in an autosomal recessive manner. Treatment should be started as soon as possible and includes BH4 supplementation usually combined with a diet without phenylalanine, folate supplementation, and specific medications to restore the levels of neurotransmitters in the brain.

What is (are) Spondyloepiphyseal dysplasia Maroteaux type ?

Spondyloepiphyseal dysplasia (SED) Maroteaux type is a rare skeletal dysplasia that is characterized by short stature beginning in infancy, short, stubby hands and feet, and genu valgum (knock knees). In addition to these physical characteristics, individuals with SED Maroteaux type have some common radiographic findings, including platyspondyly (flattened vertebral bodies in the spine), abnormalities of the pelvis and severe brachydactyly (short fingers and toes). Intelligence is generally normal and there is no clouding of the cornea, which distinguishes SED Maroteaux type from other forms of spondyloepiphyseal dysplasia. SED Maroteaux type is caused by mutations in the TRPV4 gene and is inherited any an autosomal dominant fashion.

What is (are) Cold urticaria ?

Cold urticaria is a condition that affects the skin. Signs and symptoms generally include reddish, itchy welts (hives) and/or swelling when skin is exposed to the cold (i.e. cold weather or swimming in cold water). This rash is usually apparent within 2-5 minutes after exposure and can last for 1-2 hours. The exact cause of cold urticaria is poorly understood in most cases. Rarely, it may be associated with an underlying blood condition or infectious disease. Treatment generally consists of patient education, avoiding exposures that may trigger a reaction, and/or medications.

What are the symptoms of Cold urticaria ?

What are the signs and symptoms of cold urticaria? The signs and symptoms of cold urticaria and the severity of the condition vary. Affected people generally develop reddish, itchy welts (hives) and/or swelling when skin is exposed to the cold (i.e. cold weather or swimming in cold water). This rash is usually apparent within 2-5 minutes after exposure and lasts for 1-2 hours. Other signs and symptoms may include: Headache Anxiety Tiredness Fainting Heart palpitations Wheezing Joint pain Low blood pressure In very severe cases, exposure to cold could lead to loss of consciousness, shock or even death.

What causes Cold urticaria ?

What causes cold urticaria? In most cases of cold urticaria, the underlying cause is poorly understood. Although the symptoms are triggered by exposure of the skin to the cold (most often when the temperature is lower than 39 degrees Fahrenheit), it is unclear why this exposure leads to such a significant reaction. Rarely, cold urticaria is associated with blood conditions or infectious disease such as cryoglobulinemia, chronic lymphocytic leukaemia, lymphosarcoma, chicken pox, viral hepatitis, and mononucleosis.

Is Cold urticaria inherited ?

Is cold urticaria inherited? Cold urticaria is not thought to be inherited. Most cases occur sporadically in people with no family history of the condition.

How to diagnose Cold urticaria ?

How is cold urticaria diagnosed? A diagnosis of cold urticaria is typically suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis and determine if there are other associated conditions. This generally involves a cold simulation test in which a cold object (such as an ice cube) is applied against the skin of the forearm for 1-5 minutes. In people affected by cold urticaria, a distinct red and swollen rash will generally develop within minutes of exposure. A complete blood count and/or metabolic tests may also be performed to determine associated diseases.

What are the treatments for Cold urticaria ?

How might cold urticaria be treated? The treatment of cold urticaria generally consists of patient education, avoiding scenarios that may trigger a reaction (i.e. cold temperatures, cold water), and/or medications. Prophylactic treatment with high-dose antihistimines may be recommended when exposure to cold is expected and can not be avoided. Additionally, affected people are often told to carry an epinephrine autoinjector due to the increased risk of anaphylaxis. Several other therapies have reportedly been used to treat cold urticaria with varying degrees of success. These include: Leukotriene antagonists Ciclosporin Systemic corticosteroids Dapsone Oral antibiotics Synthetic hormones Danazol

What is (are) Non-A-E hepatitis ?

What causes Microhydranencephaly ?

What causes microhydranencephaly? In many cases, the exact, underlying cause of microhydranencephaly is unknown. There are reports of families in which the condition is caused by changes (mutations) in the NDE1 gene. In these rare cases, more than one family member (often a pair of siblings) had the condition.

Is Microhydranencephaly inherited ?

Is microhydranencephaly inherited? Most cases of microhydranencephaly occur sporadically in people with no family history of the condition. However, the condition can rarely affect more than one family member and be inherited in an autosomal recessive manner. In these cases, an affected person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not have signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to have the condition, a 50% (1 in 2) chance to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.

How to diagnose Microhydranencephaly ?

How is microhydranencephaly diagnosed? A diagnosis of microhydranencephaly is generally suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. This generally consists of imaging studies to evaluate the brain for structural abnormalities and severe hydrocephalus (accumulation of fluid in the brain).

What causes Primary melanoma of the central nervous system ?

What causes primary melanoma of the central nervous system? Although the exact cause of this condition is unknown, researchers have identified somatic mutations in the the GNAQ gene in 7 of 19 patients (37 percent) with primary malignant melanocytic tumors of the central nervous system.

What is (are) Spinocerebellar ataxia 13 ?

Spinocerebellar ataxia 13 (SCA13) is a rare sub-type of spinocerebellar ataxias, a group of neurological conditions characterized by degeneration of the brain and spinal cord. Signs and symptoms of SCA13 appear to vary among affected people and range from childhood-onset, slowly progressive gait ataxia and dysarthria (often with intellectual disability and occasional seizures) to adult-onset progressive ataxia. Life expectancy is normal. SCA13 is caused by mutations in the KCNC3 gene and is inherited in an autosomal dominant manner. Treatment may include anti-seizure medications; assistive devices (such as a canes and walkers); and/or speech therapy and communication devices.

It is characterized by thick crusts of skin that contain large numbers of scabies mites and eggs. The usual features of scabies (itching and a rash) are often absent. Crusted scabies is very contagious and can spread easily both by direct skin-to-skin contacts and through contaminated items such as clothing, bedding, and furniture. People with crusted scabies should receive quick and agressive medical treatment for their infestation to prevent outbreaks of scabies. Ivermectin is commonly used to treat this form of scabies.

What is (are) Refsum disease, infantile form ?

Infantile Refsum disease is the mildest of a group of disorders known as peroxisome biogenesis disorders, Zellweger syndrome spectrum (PBD-ZSS). PBD-ZSS is a group of inherited genetic disorders that damage the white matter of the brain and affect motor movements. Peroxisome biogenesis disorders, in turn, are part of a larger group of disorders called leukodystrophies. IRD can cause low muscle tone (hypotonia), retinitis pigmentosa (a visual impairment that can lead to blindness), developmental delay, sensorineural hearing loss, and liver dysfunction. IRD usually presents at birth or in infancy. Most individuals with IRD can achieve motor milestones, though they may be delayed, and most individuals can communicate with a few words or signs. Leukodystrophy with loss of acquired skills can occur at any age and may stabilize or progress. Peroxisome biogenesis disorders are caused by mutations in one of the PEX genes and are inherited in an autosomal recessive manner. Life expectancy, medical complications, and the degree of neurological impairment can vary. Survival into adulthood is possible. Adult Refsum disease and infantile refsum disease are separate disorders caused by different genetic defects.

The condition may be mild or severe. People with the severe form may have problems with vision, breathing, speech, and swallowing. Many adults with cherubism have a normal facial appearance. Most people with cherubism do not any other signs and symptoms. The condition is inherited in an autosomal dominant fashion and is caused by mutations in the SH3BP2 gene., in most cases.

What are the symptoms of Cherubism ?

What are the signs and symptoms of Cherubism? Cherubism is characterized by abnormal bone tissue in the lower part of the face. Beginning in early childhood, both the lower jaw (the mandible) and the upper jaw (the maxilla) become enlarged as bone is replaced with painless, cyst-like growths. These growths give the cheeks a swollen, rounded appearance and often interfere with normal tooth development. In some people the condition is very mild and barely noticeable, while in other cases are severe enough to cause problems with vision, breathing, speech, and swallowing. Enlargement of the jaw usually continues throughout childhood and stabilizes during puberty. The abnormal growths are gradually replaced with normal bone in early adulthood. As a result, many affected adults have a normal facial appearance. The Human Phenotype Ontology provides the following list of signs and symptoms for Cherubism.

What is (are) Hypohidrotic ectodermal dysplasia ?

Hypohidrotic ectodermal dysplasia (HED) is a genetic skin disease. Common symptoms include sparse scalp and body hair, reduced ability to sweat, and missing teeth. HED is caused by mutations in the EDA, EDAR, or EDARADD genes. It may be inherited in an X-linked recessive, autosomal recessive, or autosomal dominant manner depending on the genetic cause of the condition. The X-linked form is the most common form. The forms have similar signs and symptoms, however the the autosomal dominant form tends to be the mildest. Treatment of hypohidrotic ectodermal dysplasia may include special hair care formulas or wigs, measures to prevent overheating, removal of ear and nose concretions, and dental evaluations and treatment (e.g., restorations, dental implants, or dentures).

How to diagnose Hypohidrotic ectodermal dysplasia ?

Is genetic testing available for hypohidrotic ectodermal dysplasia? Yes. Genetic testing for hypohidrotic ectodermal dysplasia is available. In most cases, hypohidrotic ectodermal dysplasia can be diagnosed after infancy based upon the physical features in the affected child. Genetic testing may be ordered to confirm the diagnosis. Other reasons for testing may include to identify carriers or for prenatal diagnosis. Clinical testing is available for detection of disease causing mutations in the EDA, EDAR, and EDARADD genes. We recommend that you speak with a health care provider or a genetics professional to learn more about your testing options. The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

What are the treatments for Hypohidrotic ectodermal dysplasia ?

How might hypohidrotic ectodermal dysplasia be treated? There is no specific treatment for HED. The condition is managed by treating the various symptoms. For patients with abnormal or no sweat glands, it is recommended that they live in places with air conditioning at home, school and work. In order to maintain normal body temperature, they should frequently drink cool liquids and wear cool clothing. Dental defects can be managed with dentures and implants. Artificial tears are used to prevent cornea damage for patients that do not produce enough tears. Surgery to repair a cleft palate is also helpful in improving speech and facial deformities.

In these cases, the sign or symptom may be rare or common.

What is (are) Primary central nervous system lymphoma ?

Primary central nervous system lymphoma (primary CNS lymphoma) is a rare form of non-Hodgkin lymphoma in which cancerous cells develop in the lymph tissue of the brain and/or spinal cord. Because the eye is so close to the brain, primary CNS lymphoma can also start in the eye (called ocular lymphoma). The signs and symptoms vary based on which parts of the central nervous system are affected, but may include nausea and vomiting; seizures; headaches; arm or leg weakness; confusion; double vision and/or hearing loss. The exact underlying cause of primary CNS lymphoma is poorly understood; however, people with a weakened immune system (such as those with acquired immunodeficiency syndrome) or who have had an organ transplant appear to have an increased risk of developing the condition. Treatment varies based on the severity of the condition and location of the cancerous cells.

What is (are) Eosinophilic fasciitis ?

Eosinophilic fasciitis is a very rare condition in which muscle tissue underneath the skin, called fascia, becomes swollen and thick. Rapid swelling can occur in the hands, arms, legs, and feet. People with this condition have a buildup of eosinophils, a type of white blood cell, in the affected fascia and muscles. The exact cause of this condition is unknown. Corticosteroids and other immune-suppressing medications are used to relieve the symptoms. Eosinophilic fasciitis is similar in appearance to scleroderma but is not related.

In these cases, the sign or symptom may be rare or common.

What are the treatments for Eosinophilic fasciitis ?

How might eosinophilic fasciitis be treated? About 10-20% of people with eosinophilic fasciitis recover spontaneously without treatment. For those who do not, glucocorticoids (0.51 mg/kg/d), such as prednisone, are the mainstay therapy. Even with treatment, improvement in symptoms can take weeks or months. Glucocorticoids are successful in treating eosionophilic fasciitis in over 70% of cases. If glucocorticoids are unsuccessful, methotrexate at low doses (1525 mg once weekly) is probably the most favored second-line treatment, especially in people with reddish to purpleish (morphea-like) skin lesions. Other treatment options include NSAIDs, D-penicillamine, chloroquine, cimetidine, azathioprine, cyclosporin A, infliximab, UVA-1, and bath PUVA. Physical therapy may help improve joint mobility and decrease contractures. Surgical release has been used in some severe cases to manage significant joint contractures.

What is (are) Occipital horn syndrome ?

Occipital horn syndrome (OHS) is characterized by sagging and non-stretchy skin (cutis laxa), wedge-shaped calcium deposits in a bone at the base of the skull (occipital bone), coarse hair, and loose joints. Individuals with OHS are said to have normal or slightly reduced intelligence. This condition is considered to be a mild type of Menkes diseases, which affects copper levels in the body. Occipital horn syndrome may be caused by mutations in the ATP7A gene, and it is inherited in an x-linked recessive pattern.

What is (are) Embryonal carcinoma ?

Embryonal carcinoma is a type of testicular cancer, which is cancer that starts in the testicles, the male reproductive glands located in the scrotum. It most often develops in young and middle-aged men. It tends to grow rapidly and spread outside the testicle. Embryonal carcinomas are classified as nonseminoma germ cell tumors. Most testicular cancers grow from germ cells, the cells that make sperm. Germ cell tumors are broadly divided into seminomas and nonseminomas because each type has a different prognosis and treatment regimen. Nonseminomas, which are more common, tend to grow more quickly than seminomas. Nonseminoma tumors are often made up of more than one type of cell, and are identified according to the different cell types.

What is (are) Isovaleric acidemia ?

Isovaleric acidemia (IVA) is a type of organic acid disorder in which affected individuals have problems breaking down an amino acid called leucine from the food they eat. Signs and symptoms may range from very mild to life-threatening. In severe cases, symptoms begin within a few days of birth and include poor feeding, vomiting, seizures, and lack of energy (lethargy); these may progress to more serious medical problems including seizures, coma, and possibly death. In other cases, signs and symptoms appear during childhood and may come and go over time. A characteristic sign of IVA is a distinctive odor of sweaty feet during acute illness. Other features may include failure to thrive or delayed development. IVA is caused by mutations in the IVD gene and is inherited in an autosomal recessive manner. Treatment involves moderate restriction of proteins in the diet and oral administration of glycine and L-carnitine which helps to rid the body of excess isovaleric acid.

What are the symptoms of Isovaleric acidemia ?

What are the signs and symptoms of Isovaleric acidemia? Health problems related to isovaleric acidemia range from very mild to life-threatening. In severe cases, the features of isovaleric acidemia become apparent within a few days after birth. The initial symptoms include poor feeding, vomiting, seizures, and lack of energy (lethargy). These symptoms sometimes progress to more serious medical problems, including seizures, coma, and possibly death. A characteristic sign of isovaleric acidemia is a distinctive odor of sweaty feet during acute illness. This odor is caused by the buildup of a compound called isovaleric acid in affected individuals. In other cases, the signs and symptoms of isovaleric acidemia appear during childhood and may come and go over time. Children with this condition may fail to gain weight and grow at the expected rate (failure to thrive) and often have delayed development. In these children, episodes of more serious health problems can be triggered by prolonged periods without food (fasting), infections, or eating an increased amount of protein-rich foods. Some people with gene mutations that cause isovaleric acidemia are asymptomatic, which means they never experience any signs or symptoms of the condition. The Human Phenotype Ontology provides the following list of signs and symptoms for Isovaleric acidemia. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Isovaleric acidemia ?

What causes isovaleric acidemia? Isovaleric acidemia is caused by mutations in the IVD gene. The IVD gene provides instructions for making an enzyme that plays an essential role in breaking down proteins from the diet. Specifically, this enzyme helps process the amino acid leucine, which is part of many proteins. If a mutation in the IVD gene reduces or eliminates the activity of this enzyme, the body is unable to break down leucine properly. As a result, an organic acid called isovaleric acid and related compounds build up to harmful levels in the body. This buildup damages the brain and nervous system, causing serious health problems.

Is Isovaleric acidemia inherited ?

How is isovaleric acidemia inherited? Isovaleric acidemia is inherited in an autosomal recessive pattern, 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 typically do not show signs and symptoms of the condition.

What are the treatments for Isovaleric acidemia ?

How might isovaleric acidemia be treated? There is currently no cure for isovaleric acidemia (IVA). Upon diagnosis, immediate treatment is typically necessary in order to prevent metabolic crises and complications that may follow. It is often recommended that affected individuals have a low-leucine / low-protein diet and use medical foods (such as special low-protein flours, pastas, and rice that are made especially for people with organic acid disorders) and leucine-free medical formula. A dietician with knowledge of IVA can help parents create a food plan that contains the right amount of protein, nutrients, and energy to keep the child healthy. Any diet changes should be under the guidance of a dietician. Medications that may be recommended include glycine and L-carnitine, which help rid the body of unwanted isovaleric acid and other harmful substances. No medication or supplement should be used without checking with a metabolic doctor. Children with symptoms of a metabolic crisis need medical treatment right away and may be given bicarbonate, glucose, and other medications by IV. With prompt and careful treatment, children with IVA have a good chance to live healthy lives with normal growth and development. However, some children, even when treated, may have repeated metabolic crises which can lead to life-long learning problems or mental retardation.

What is (are) Mixed connective tissue disease ?

Mixed connective tissue disease (MCTD) is a rare autoimmune disorder that is characterized by features commonly seen in three different connective tissue disorders: systemic lupus erythematosus, scleroderma, and polymyositis. Some affected people may also have symptoms of rheumatoid arthritis. Although MCTD can affect people of all ages, it appears to be most common in women under age 30. Signs and symptoms vary but may include Raynaud's phenomenon; arthritis; heart, lung and skin abnormalities; kidney disease; muscle weakness, and dysfunction of the esophagus. The cause of MCTD is currently unknown. There is no cure but certain medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immunosuppresive drugs may help manage the symptoms.

What are the symptoms of Mixed connective tissue disease ?

What are the signs and symptoms of Mixed connective tissue disease? People with mixed connective tissue disease (MCTD) have symptoms that overlap with several connective tissue disorders, including systemic lupus erythematosus, polymyositis, scleroderma, and rheumatoid arthritis. A condition called Raynaud's phenomenon sometimes occurs months or years before other symptoms of MCTD develop. Most people with MCTD have pain in multiple joints, and/or inflammation of joints (arthritis). Muscle weakness, fevers, and fatigue are also common. Other signs and symptoms may include: Accumulation of fluid in the tissue of the hands that causes puffiness and swelling (edema) Skin findings including lupus-like rashes (including reddish brown patches), reddish patches over the knuckles, violet coloring of the eyelids, loss of hair (alopecia), and dilation of small blood vessels around the fingernails (periungual telangiectasia) Dysfunction of the esophagus (hypomotility) Abnormalities in lung function which may lead to breathing difficulties, and/or pulmonary hypertension Heart involvement (less common in MCTD than lung problems) including pericarditis, myocarditis, and aortic insufficiency Kidney disease Neurologic abnormalities (in about 10 percent of people with MCTD) such as organic brain syndrome; blood vessel narrowing causing "vascular" headaches; a mild form of meningitis; seizures; blockage of a cerebral vessel (cerebral thrombosis) or bleeding; and/or various sensory disturbances in multiple areas of the body (multiple peripheral neuropathies) Anemia and leukopenia (in 30 to 40 percent of cases) Lymphadenopathy, enlargement of the spleen (splenomegaly), enlargement of the liver (hepatomegaly), and/or intestinal involvement in some cases The Human Phenotype Ontology provides the following list of signs and symptoms for Mixed connective tissue disease.

What causes Mixed connective tissue disease ?

What causes mixed connective tissue disease? The exact underlying cause of mixed connective tissue disease (MCTD) is currently unknown. It is an autoimmune disorder, which means the immune system mistakes normal, healthy cells for those that that body should "fight off." There are ongoing studies exploring how immune system dysfunction may be involved in the development of this condition.

Is Mixed connective tissue disease inherited ?

Is mixed connective tissue disease inherited? The role of genetics in the onset of mixed connective tissue disease (MCTD) is still unclear. Some people with MCTD have family members who are also affected by the condition. This suggests that in some cases, an inherited predisposition may contribute to the development of MCTD. People with an inherited or genetic predisposition have an increased risk of developing a certain condition due to their genes.

How to diagnose Mixed connective tissue disease ?

How is mixed connective tissue disease diagnosed? Mixed connective tissue disease (MCTD) is often suspected after a physical examination reveals signs and symptoms associated with the condition. The diagnosis is supported by a blood test that shows high levels of antibodies associated with MCTD.

What are the treatments for Mixed connective tissue disease ?

How might mixed connective tissue disease be treated? There is currently no cure for mixed connective tissue disease (MCTD). However, treatments can help manage symptoms of the condition. For example, medications such as over-the-counter or prescription nonsteroidal anti-inflammatory drugs may help with inflammation and pain of the muscles or joints. Glucocorticoids may be recommended in certain situations, such as during disease flares or when complications arise (e.g., aseptic meningitis, myositis, pleurisy, pericarditis, and myocarditis). Some people with MCTD require long term use of immunosuppressant medications. Additional medications may be prescribed based on the signs and symptoms present in each person. For example, if a person with MCTD has developed symptoms similar to those of lupus, medications typically prescribed for people with lupus may be recommended. For additional information about the treatment of MCTD, visit the Mayo Foundation for Medical Education and Research Web site.

What is (are) Thalassemia ?

Thalassemia is an inherited blood disorder that reduces the production of functional hemoglobin (the protein in red blood cells that carries oxygen). This causes a shortage of red blood cells and low levels of oxygen in the bloodstream, leading to a variety of health problems. There are two main types of thalassemia, alpha thalassemia and beta thalassemia. Signs and symptoms vary but may include mild to severe anemia, paleness, fatigue, yellow discoloration of skin (jaundice), and bone problems. Beta thalassemia is caused by changes (mutations) in the HBB gene while alpha thalassemia is caused by mutations in the HBA1 and/or HBA2 genes. Both are inherited in an autosomal recessive manner. Treatment depends on the type and severity of the condition but may include blood transfusions and/or folic acid supplements.

What are the symptoms of Thalassemia ?

What are the signs and symptoms of Thalassemia? The signs and symptoms vary depending on the severity of the thalassemia. For example, people affected by milder forms of thalassemia can develop mild anemia or may have no signs or symptoms of the condition at all. Intermediate forms of thalassemia can cause mild to moderate anemia and may be associated with other health problems such as slowed growth, delayed puberty, bone problems and/or an enlarged spleen. In addition to the signs and symptoms seen in intermediate thalassemia, people with severe forms of thalassemia may also experience severe anemia, poor appetite, paleness, dark urine, yellow discoloration of skin (jaundice), and enlarged liver or heart.

What causes Thalassemia ?

What causes thalassemia? There are two main types of thalassemia, alpha thalassemia and beta thalassemia, which each affect a different part of hemoglobin (the protein in red blood cells that carries oxygen). Hemoglobin is made up of two different components (subunits): beta globin and alpha globin. The HBB gene provides instructions for making beta globin, while the HBA1 and HBA2 genes provide instructions for making alpha globin. Each person has two copies of each of these genes, one inherited from the mother and one from the father. Changes (mutations) in the HBB gene lead to reduced levels of beta globin and cause beta thalassemia. Loss (deletion) of some or all of the HBA1 and/or HBA2 genes results in a shortage of alpha globin, leading to alpha thalassemia.

Is Thalassemia inherited ?

How is thalassemia inherited? In general, thalassemia is inherited in an autosomal recessive manner; however, the inheritance can be quite complex as multiple genes can influence the production of hemoglobin. Most people affected by beta thalassemia have mutations in both copies of the HBB gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition; although some carriers of beta thalassemia develop mild anemia. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. The inheritance of alpha thalassemia is complicated by the fact that mutations in two different genes (HBA1 and HBA2) are associated with the condition. People have two copies of the HBA1 gene and two copies of the HBA2 gene in each cell. For each gene, one copy is inherited from the mother and one is inherited from the father. If each parent is missing at least one gene copy, their children are at risk for having alpha thalassemia. However, the exact risk and the severity of each child's condition depends on how many gene copies are lost (deleted) and which combination of the HBA1 and HBA2 genes are affected.

How to diagnose Thalassemia ?

Is genetic testing available for thalassemia? Yes, genetic testing is available for HBB, HBA1 and HBA2, the genes known to cause thalassemia. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutations in the family are known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. It has additional information on genetic testing for alpha thalassemia and beta thalassemia. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

What are the treatments for Thalassemia ?

How might thalassemia be treated? The best treatment options depend on the severity of thalassemia. People affected by a mild form often need little to no treatment, while people with intermediate to severe thalassemias may require frequent blood transfusions, iron chelation therapy (treatments to remove excess iron from the body), and/or folic acid supplementation.

While affected individuals are typically of normal length at birth, their growth rate tends to fall below the standard growth curve by age two. The average height of an adult male is 3 feet, 11 inches and the average height of an adult female is 3 feet, 9 inches. Other features of pseudoachondroplasia include short arms and legs, a waddling walk, early-onset joint pain (osteoarthritis), and a limited range of motion at the elbows and hips. Some individuals develop abnormal curvatures of the spine (scoliosis and/or lordosis) during childhood. People with pseudoachondroplasia have normal facial features, head size, and intelligence.

Is Pseudoachondroplasia inherited ?

How is pseudoachondroplasia inherited? Pseudoachondroplasia is inherited in an autosomal dominant pattern, which means having one altered copy of the COMP gene in each cell is enough to cause the disorder. In some cases, an affected person inherits the mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family.

What is (are) Primary lateral sclerosis ?

Primary lateral sclerosis is a type of motor neuron disease, where nerve cells that control voluntary muscle movement breakdown and die. In primary lateral sclerosis only the upper motor neurons in the brain are affected. Symptoms often begin with problems in the legs (e.g., weakness, stiffness, spasticity, and balance problems), but may also start with hand clumsiness and changes in speech. The symptoms worsen gradually over time, however people with this condition have a normal life expectancy. Progression of symptoms varies from person to person, some people retain the ability to walk without assistance, others eventually require assistive devices such as canes or wheelchairs. Diagnosis requires extensive testing to exclude other diseases. Treatment may include baclofen and tizanidine to reduce spasticity, quinine or phenytoin to reduce cramps, as well as physical and speech therapy as required.

What are the symptoms of Primary lateral sclerosis ?

What are the signs and symptoms of Primary lateral sclerosis? Primary lateral sclerosis (PLS) causes weakness in the voluntary muscles, such as those used to control the legs, arms and tongue. PLS can happen at any age, but it is more common after age 40. A subtype of PLS, known as juvenile primary lateral sclerosis, begins in early childhood. PLS is often mistaken for another, more common motor neuron disease called amyotrophic lateral sclerosis (ALS). However, primary lateral sclerosis progresses more slowly than ALS, and in most cases is not considered fatal. Signs and symptoms of PLS typically take years to progress. The hallmark of PLS is progressive weakness and spasticity of voluntary muscles. The first symptoms are often tripping or difficulty lifting the legs. Other people may be the first to notice a change in the affected person's gait. Occasionally, speaking (dysarthria) and swallowing (dysphasia) difficulties, or arm weakness are the first symptoms. Speech problems can begin with hoarseness, a reduced rate of speaking, excessive clearing of the throat, or slurred speech when a person is tired. In some cases, speech becomes so slurred that others cannot understand it. Drooling can be a problem as well due to weakened bulbar muscles. Many people report painful muscle spasms and other pain. Other common symptoms may include hyperactive reflexes and Babinkski's sign. Wherever symptoms originate, the legs, arms, hands, and speech and swallowing muscles are eventually affected. As the disease progresses, assistive devices such as canes, walkers or wheelchairs are typically needed. The Human Phenotype Ontology provides the following list of signs and symptoms for Primary lateral sclerosis. If the information is available, the table below includes how often the symptom is seen in people with this condition.

How to diagnose Primary lateral sclerosis ?

How is primary lateral sclerosis diagnosed? There is no single test that confirms a diagnosis of primary lateral sclerosis (PLS). Because the disease can mimic signs and symptoms of other neurological diseases such as multiple sclerosis and amyotrophic lateral sclerosis (ALS), several tests are done to rule out other diseases. After taking a careful record of an individual's medical history and performing a complete neurological examination, a doctor may order the following tests: Blood work. Blood tests are done to check for infections or other possible causes of muscle weakness. Magnetic resonance imaging (MRI) of the brain and spine. An MRI or other imaging tests may reveal signs of nerve cell degeneration and look for other causes of symptoms, such as structural abnormalities, spinal cord compression, multiple sclerosis and spinal cord tumors. Motor and sensory nerve conduction studies. These tests use a low amount of electrical current to test how quickly the nerves carry impulses through the body, and can indicate damage to nerve cells. Electromyogram (EMG). During this test, the doctor inserts a needle electrode through the skin into various muscles. The electrical activity of the muscles is evaluated when they contract and when they're at rest. This test can measure the involvement of lower motor neurons, which can help to differentiate between PLS and ALS. Cerebrospinal fluid (CSF) analysis. An analysis of the CSF, which is taken during a lumbar puncture in the lower back, can help to rule out multiple sclerosis and other causes of spasticity. After other diseases are ruled out, a doctor may make a preliminary diagnosis of PLS. Sometimes doctors wait three to four years before being sure of the diagnosis, because early ALS can look just like PLS until additional symptoms surface a few years later.

What is (are) Multiple mitochondrial dysfunctions syndrome ?

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.
