What is (are) Neuropathy ataxia retinitis pigmentosa syndrome ? | Neuropathy ataxia retinitis pigmentosa (NARP) syndrome is characterized by a variety of signs and symptoms that mainly affect the nervous system. Beginning in childhood or early adulthood, most people with NARP experience numbness, tingling, or pain in the arms and legs (sensory neuropathy); muscle weakness; and problems with balance and coordination (ataxia). Affected individuals may also have vision loss caused by a condition called retinitis pigmentosa. Other features of NARP include learning disabilities, developmental delay, seizures, dementia, hearing loss, and cardiac conduction defects. Mutations in the MT-ATP6 gene cause NARP syndrome. This gene is located within mitochondrial DNA (mtDNA). Most individuals with NARP have a specific MT-ATP6 mutation in 70 percent to 90 percent of their mitochondria. NARP syndrome is inherited from the mother (maternal inheritance) because only females pass mitochondrial DNA to their children. | |

What is (are) Alopecia universalis ? | Alopecia universalis (AU) is a condition characterized by the complete loss of hair on the scalp and body. It is an advanced form of alopecia areata, a condition that causes round patches of hair loss. Although the exact cause of AU is unknown, it is thought to be an autoimmune condition in which an affected person's immune system mistakenly attacks the hair follicles. Roughly 20% of affected people have a family member with alopecia, suggesting that genetic factors may contribute to the development of AU. There is currently no cure for AU, but sometimes hair regrowth occurs on it's own, even after many years. | |
What are the symptoms of Alopecia universalis ? | What are the signs and symptoms of Alopecia universalis? Alopecia universalis (AU) is characterized by the complete loss of hair on both the scalp and body. Most people with AU do not have other signs and symptoms, but some may experience a burning sensation or itching on affected areas. In some cases, AU can be associated with other conditions such as atopic dermatitis, thyroid disorders, and/or nail changes (such as pitting).

What causes Alopecia universalis ? | What causes alopecia universalis? The exact underlying cause of alopecia universalis (AU) is not currently known. AU is an advanced form of alopecia areata (AA), a condition that leads to round patches of hair loss. AA is thought to be an autoimmune condition in which an affected person's immune system mistakenly attacks the hair follicles. Genetic studies have found that AA and AU are associated with several immune-related genes; however, they are likely complex disorders caused by the interaction of multiple genetic and environmental factors. This means that even if someone inherits a genetic predisposition to the condition, they may not become affected unless something in the environment triggers the onset of the condition. | |
Is Alopecia universalis inherited ? | Is alopecia universalis inherited? Alopecia universalis is believed to be a multifactorial condition, which means it is caused by a combination of environmental influences and genetic predisposition. While a predisposition can be inherited and some affected people have a family history, the condition itself is not thought to be inherited. | |
How to diagnose Alopecia universalis ? | How is alopecia universalis diagnosed? A diagnosis of alopecia universalis is usually based on the signs and symptoms present in each person. In rare cases, a scalp biopsy may be needed to confirm the diagnosis. | |
What are the treatments for Alopecia universalis ? | How might alopecia universalis be treated? Although these is no therapy approved for the treatment of alopecia universalis, some people find that medications approved for other purposes may help hair grow back, at least temporarily. Since alopecia universalis is one of the more severe types of alopecia areata, treatment options are somewhat limited. The most common treatments include corticosteriods and topical (applied to the skin) immunotherapy. There are possible side effects of corticosteriods which should be discussed with a physician. Also, regrown hair is likely to fall out when the corticosteriods are stopped. About 40% of people treated with topical immunotherapy will regrow scalp hair after about six months of treatment. Those who do successfully regrow scalp hair need to continue the treatment to maintain the hair regrowth. While these treatments may promote hair growth, they do not prevent new loss or cure the underlying disease. For those who do not respond to treatment, wigs are an option. | |

What is (are) Frontal fibrosing alopecia ? | Frontal fibrosing alopecia (FFA) is a form of lichen planus follicularis that is characterized primarily by slowly progressive hair loss (alopecia) and scarring on the scalp near the forehead. In some cases, the eyebrows, eye lashes and/or other parts of the body may be involved, as well. Although it has been suggested that FFA may be due to hormonal changes or an autoimmune response, the exact cause of this condition is not yet known. There is currently no cure for FFA; however, treatment with certain types of medications may stop or slow hair loss in some cases. | |
What are the symptoms of Frontal fibrosing alopecia ? | What are the signs and symptoms of frontal fibrosing alopecia? Frontal fibrosing alopecia (FFA) is characterized primarily by hair loss (alopecia) and scarring on the scalp near the forehead. The band of hair loss on the front and sides of the scalp is usually symmetrical and slowly progressive (worsening over time). The skin in the affected area often looks normal but may be pale, shiny or mildly scarred. Approximately half of all affected people experience loss of eyebrows, as well. Less commonly, the eyelashes may also be involved. Some people with FFA develop hair loss in areas other than the scalp and face. In some cases, women with FFA also have female pattern hair loss, which is associated with thinning of hair on the scalp due to increased hair shedding and/or a reduction in hair volume. | |
What causes Frontal fibrosing alopecia ? | What causes frontal fibrosing alopecia? The exact underlying cause of frontal fibrosing alopecia (FFA) is unknown. FFA is thought to be an autoimmune condition in which an affected person's immune system mistakenly attacks the hair follicles (structures in the skin that make hair). Scientists also suspect that there may be a hormonal component since the condition most commonly affects post-menopausal women over age 50. | |
Is Frontal fibrosing alopecia inherited ? | Is frontal fibrosing alopecia inherited? Frontal fibrosing alopecia is not thought to be inherited in most cases. It rarely affects more than one person in a family. | |
How to diagnose Frontal fibrosing alopecia ? | How is frontal fibrosing alopecia diagnosed? Frontal fibrosing alopecia is often suspected based on the presence of characteristic signs and symptoms. The diagnosis can be confirmed by examining a small sample of skin (skin biopsy) from the affected area. In some cases, laboratory studies may be ordered to rule out other conditions that cause similar features. | |
What are the treatments for Frontal fibrosing alopecia ? | How might frontal fibrosing alopecia be treated? Unfortunately, there is currently no cure for frontal fibrosing alopecia (FFA). Because the hair loss associated with this condition is thought to be caused by inflammation of hair follicles, treatment often involves using anti-inflammatory medications or ointments, such as corticosteroids or hydroxychloroquine (brand name Plaquenil), to reduce inflammation and suppress the body's immune system. Medications that block the production of the male hormone 5-alpha reductase have been reported to stop further hair loss in some women. Researchers continue to question whether treatment is effective or if hair loss in FFA just stops naturally. | |
What is (are) Chromosome 7q deletion ? | Chromosome 7q 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 7. 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 7q 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. | |

What is (are) Hemoglobin E disease ? | Hemoglobin E (HbE) disease is an inherited blood disorder characterized by an abnormal form of hemoglobin, called hemoglobin E. People with this condition have red blood cells that are smaller than normal and have an irregular shape. HbE disease is thought to be a benign condition. It is inherited in an autosomal recessive pattern and is caused by a particular mutation in the HBB gene. The mutation that causes hemoglobin E disease has the highest frequency among people of Southeast Asian heritage (Cambodian, Laotian, Vietnamese and Thai). However, it is also found in people of Chinese, Filipino, Asiatic Indian, and Turkish descent. | |
What are the symptoms of Hemoglobin E disease ? | What are the signs and symptoms of hemoglobin E disease? Affected individuals can develop mild thalassemia in the first few months of life. While mild splenomegaly and/or anemia can occur, it is generally considered a benign condition. When a person inherits a gene mutation from one of their parents, they are said to be a carrier or have hemoglobin trait. These individuals are typically asymptomatic, although they may have small red blood cells. However, carriers may be at risk to have children with hemoglobin E/thalassemia (which is similar to thalassemia) or hemoglobin sickle E disease (milder form of sickle cell anemia). Both of these conditions are much more severe than hemoglobin E disease. They are are also inherited in an autosomal recessive fashion. | |
How to diagnose Hemoglobin E disease ? | How is hemoglobin E disease diagnosed? Many babies are picked up through state newborn screening programs. A diagnosis is usually made by looking at the red blood cells by doing a Mean Corpuscular Volume (MCV) test, which is commonly part of a Complete Blood Count (CBC) test. More specialized tests, such as a hemoglobin electrophoresis and iron studies might be done. These tests indicate whether a person has different types of hemoglobin. Genetic testing of the HBB gene can also be done to confirm a diagnosis. | |
What are the treatments for Hemoglobin E disease ? | How might hemoglobin E disease be treated? Treatment is usually not necessary. Folic acid supplements may be prescribed to help the body produce normal red blood cells and improve symptoms of anemia. People with hemoglobin E disease can expect to lead a normal life. | |

What is (are) Pachyonychia congenita ? | Pachyonychia congenita (PC) is a rare inherited condition that primarily affects the nails and skin. The fingernails and toenails may be thickened and abnormally shaped. Affected people can also develop painful calluses and blisters on the soles of their feet and less frequently on the palms of their hands (palmoplantar keratoderma). Additional features include white patches on the tongue and inside of the mouth (leukokeratosis); bumps around the elbows, knees, and waistline (follicular hyperkeratosis); and cysts of various types including steatocystoma. Features may vary among affected people depending on their specific mutation. PC is divided into 5 types based on the specific keratin gene involved: PC-K6a, PC-K6b, PC-K6c, PC-K16, and PC-K17. All forms are inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person. | |

However, the most common features of the condition include: Thickened nails Plantar hyperkeratosis (thickened skin on the soles of the feet) with underlying blisters Plantar pain Various types of cysts (i.e. steatocystoma and pilosebaceous cysts - two types of sebaceous gland cysts) Follicular hyperkeratosis (small bumps at the base of hairs) Leukokeratosis (white patches on the tongue, in the mouth, or on the inside of the cheek) Some affected people may also develop calluses on the palms of the hands (palmar hyperkeratosis), sores at the corner of the mouth; natal teeth; a hoarse cry or voice caused by white film on the larynx (voice box); and/or intense pain when beginning to eat or swallow. For more specific information on the signs and symptoms of PC, including specific features that are not associated with the condition, please visit the Pachyonychia Congenita Project's Web site. The Human Phenotype Ontology provides the following list of signs and symptoms for Pachyonychia congenita. If the information is available, the table below includes how often the symptom is seen in people with this 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 causes Pachyonychia congenita ? | What causes pachyonychia congenita? Pachyonychia congenita (PC) is caused by changes (mutations) in one of five genes: KRT6A, KRT6B, KRT6C, KRT16, and KRT17. These genes provide instructions for making a protein called keratin, which is found in the skin, hair, and nails. Mutations in any of these genes alter the structure of keratin proteins which interferes with their ability to provide strength and resilience to various parts of the body. This leads to the many signs and symptoms associated with pachyonychia congenita. PC is divided into 5 types based on the specific keratin gene involved: PC-K6a, PC-K6b, PC-K6c, PC-K16, and PC-K17. | |
Is Pachyonychia congenita inherited ? | How is pachyonychia congenita inherited? Pachyonychia congenita (PC) is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with PC has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Pachyonychia congenita ? | Is genetic testing available for pachyonychia congenita? Yes, genetic testing is available for the five genes known to cause pachyonychia congenita. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. 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. How is pachyonychia congenita diagnosed? A diagnosis of pachyonychia congenita (PC) is often suspected based on the presence of characteristic signs and symptoms. In fact, one study found that approximately 97% of people with genetically confirmed PC have toenail thickening, plantar keratoderma (thickening of the skin on the soles of the feet) and plantar pain by age ten. Identification of a change (mutation) in one of the five genes associated with PC confirms the diagnosis. | |
What are the treatments for Pachyonychia congenita ? | How might pachyonychia congenita be treated? There is no cure for pachyonychia congenita (PC). Current management is focused on relief of pain and other symptoms; hygienic grooming practices (such as trimming the nails and calluses); and treatment of infections when necessary. Some affected people may also require aids to help with mobility, such as wheelchairs, crutches and/or canes. Pachyonychia Congenita Project offers more detailed information regarding the treatment and management of PC. Please click on the link to access this resource. | |
What is (are) Adenoid cystic carcinoma ? | Adenoid cystic carcinoma (ACC) is a rare form of adenocarcinoma, which is cancer that begins in gladular tissues. ACC most commonly arises in the head and neck, in various parts of the major and minor salivary glands including the palate, nasopharynx, lining of the mouth, voice box (larynx) or windpipe (trachea). It can also occur in the breast, uterus, or other locations in the body. Early symptoms depend on the tumor's location and may include lumps under the lining of the mouth or facial skin; numbness in the mouth or face; difficulty swallowing; hoarseness; pain; or paralysis of a facial nerve. ACC often has long periods with no growth followed by growth spurts; however, it can be aggressive in some people. ACC spreads along nerves or through the bloodstream, and only spreads to the lymph nodes in about 5-10% of cases. The cause of ACC is currently unknown. Treatment depends on many factors and may include surgery, radiation, and/or chemotherapy. | |
What causes Adenoid cystic carcinoma ? | What causes adenoid cystic carcinoma? The underlying cause of adenoid cystic carcinoma (ACC) is not yet known, and no strong genetic or environmental risk factors specific to ACC have been identified. Researchers believe that a combination of various genetic and environmental factors probably interact to ultimately cause a person to develop specific types of cancers. There is ongoing research to learn more about the many factors that contribute to the development of cancer. Cancer is at least partly due to acquired (not inherited) damage or changes to the DNA in certain cells. For example, various studies have shown that chromosomal abnormalities and genetic deletions are present in samples of ACC. However, these genetic abnormalities are present only in the cancer cells, not in the cells with the genetic material that is passed on to offspring (the egg and sperm cells). | |
Is Adenoid cystic carcinoma inherited ? | Is adenoid cystic carcinoma inherited? While the underlying cause of adenoid cystic carcinoma (ACC) is not known, no strong genetic risk factors have been identified. To our knowledge, only one case of apparent familial ACC has been reported worldwide. In this case, a father and daughter were both affected with ACC of the sublingual salivary gland. While ACC appears to generally be sporadic (occurring in people with no family history of ACC), there has been speculation about a possible linkage between salivary gland cancers in general and inherited BRCA gene mutations. However, this potential link needs further investigation. There has also been one report of a case of ACC of the salivary gland occurring in a person with basal cell nevus syndrome, a hereditary syndrome known to predispose affected people to a very wide range of tumors. | |
What is (are) Waardenburg syndrome type 2 ? | 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 are the symptoms of Waardenburg syndrome type 2 ? | What are the signs and symptoms of 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. The Human Phenotype Ontology provides the following list of signs and symptoms for Waardenburg syndrome type 2. If the information is available, the table below includes how often the symptom is seen in people with this condition.

In these cases, the sign or symptom may be rare or common. | |
How to diagnose Waardenburg syndrome type 2 ? | How is a subtype of Waardenburg syndrome type 2 diagnosed? 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. | |
What is (are) Autoimmune gastrointestinal dysmotility ? | 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. | |

What is (are) Pyle disease ? | 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. | |

Is Pyle disease inherited ? | Is Pyle disease inherited? 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 don't have any signs and symptoms of the condition. Some carriers (obligate heterozygotes) of Pyle disease show minor skeletal changes. | |
What is (are) Idiopathic juxtafoveal retinal telangiectasia ? | Idiopathic juxtafoveal retinal telangiectasia (IJT) refers to a group of eye conditions characterized by dilated or twisting blood vessels (telangiectasia) and defective capillaries (tiny blood vessels) near the fovea in the retina. The fovea has the biggest number of special retinal nerve cells, called cones, which enable sharp, daytime vision. In IJT, the telangiectasias cause fluid or crystal buildup and swelling, impairing reflection of light. This results in progressive vision loss. It may be congenital (present at birth) or can develop during the lifetime (acquired). The different types of IJT are distinguished by their features and treatment options. Laser photocoagulation maybe helpful in treating vision loss for individuals with certain types of IJT. | |
What are the symptoms of Idiopathic juxtafoveal retinal telangiectasia ? | What are the signs and symptoms of idiopathic juxtafoveal retinal telangiectasia? Signs and symptoms of idiopathic juxtafoveal retinal telangiectasia may include slow loss of vision, distorted vision, trouble reading, and scotomata (a spot in the visual field in which vision is absent or deficient). | |
What causes Idiopathic juxtafoveal retinal telangiectasia ? | What causes idiopathic juxtafoveal retinal telangiectasia? The exact, underlying cause of idiopathic juxtafoveal retinal telangiectasia (IJT) is not known. IJT has been reported in some siblings (including twins) and other family members of affected people. This suggests there may be a genetic component to IJT; however, no specific gene has been proven to cause the condition. Researchers have considered that changes in the ATM gene may interact with other genes or environmental factors to predispose a person to developing IJT. Some researchers have speculated that diabetes, or pre-diabetes, may be associated with some cases of IJT. However, to our knowledge, this association has not been proven. Others have suggested there may be a developmental cause, such as abnormal formation of vessels in the eye, which could cause abnormalities of the vessels in adulthood. Certain types of IJT may occur in association with other conditions, including polycythemia (abnormal increase in blood volume), hypoglycemia, ulcerative colitis, multiple myeloma and chronic lymphatic leukemia. | |
What are the treatments for Idiopathic juxtafoveal retinal telangiectasia ? | How might idiopathic juxtafoveal retinal telangiectasia (IJT) be treated? Laser photocoagulation of areas of leakage may be helpful in treating vision loss in people with certain subtypes of IJT, such as Group 1A. A laser is a powerful beam of light which can be focused on the retina. Small "bursts" of the laser can be used to seal leaky blood vessels, destroy abnormal blood vessels, seal retinal tears, and destroy abnormal tissue in the back of the eye. Photocoagulation usually is not considered for people with people in Group 1B because of the closeness of the leakage to the fovea, and the good prognosis without treatment. It may benefit people in Group 2 but in most cases, the abnormal lesions are so close to the fovea that treatment is difficult. | |
What is (are) Glutathione synthetase deficiency ? | Glutathione synthetase deficiency is type of organic acidemia that affects the production glutathione. Glutathione helps prevent cell damage, build DNA and proteins, and process medications and cancer-causing compounds. People can have mild, moderate, or severe disease. Mild disease may cause hemolytic anemia and 5-oxoprolinuria (excess excretion of 5-oxoproline in urine). Moderate disease may cause anemia, 5-oxoprolinuria, and metabolic acidosis in early infancy. Severe disease may cause anemia, 5-oxoprolinuria, metabolic acidosis, neurological symptoms (e.g., seizures, learning disability, loss of coordination), and recurrent infections. It is caused by mutations in the GSS gene and is inherited in an autosomal recessive fashion. | |

What is (are) Pyruvate carboxylase deficiency ? | Pyruvate carboxylase deficiency is an inherited disorder that causes lactic acid and other potentially toxic compounds to accumulate in the blood. High levels of these substances can damage the body's organs and tissues, particularly in the nervous system. Researchers have identified at least three types of pyruvate carboxylase deficiency, types A, B, and C, which are distinguished by the severity of their signs and symptoms. This condition is caused by mutations in the PC gene and inherited in an autosomal recessive pattern. | |

Is Pyruvate carboxylase deficiency inherited ? | How is pyruvate carboxylase deficiency inherited? Pyruvate carboxylase deficiency is inherited in an autosomal recessive manner. This means that both copies of the disease-causing gene in each cell (usually one inherited from each parent) must have a mutation for an individual to be affected. Individuals who carry one mutated copy of the gene are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers for 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 an unaffected carrier like each of the parents, and a 25% risk to not have the condition and not be a carrier (i.e. to inherit both normal genes). In other words, each child born to two carriers has a 75% (3 in 4) chance to be unaffected. De novo mutations (new mutations that occur for the first time in an individual and are not inherited from a parent) have been reported for this condition. This means that in some cases, an affected individual may have only one parent who is a carrier for the condition. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk may be possible through laboratories offering custom mutation analysis if the disease-causing mutations in a family are known. Individuals interested in learning more about genetic risks to themselves or family members, or about genetic testing for this condition, should speak with a genetics professional. | |

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 is (are) Nonalcoholic steatohepatitis ? | Nonalcoholic steatohepatitis, or NASH, is a common, often silent liver disease. It resembles alcoholic liver disease, but occurs in people who drink little or no alcohol. The major feature in NASH is fat in the liver, along with inflammation and damage. Most people with NASH feel well and are not aware that they have a liver problem. Nevertheless, NASH can be severe and can lead to cirrhosis, in which the liver is permanently damaged and scarred and no longer able to work properly. NASH most often occurs in people who are middle aged and overweight or obese. Affected individuals may also have elevated levels of blood lipids (such as cholesterol and triglycerides) and many have diabetes or prediabetes. Treatment is centered around working towards a healthy lifestyle, including weight reduction, dietary modification, increased activity and avoidance of alcohol and unnecessary medications. The underlying cause of NASH remains unclear. | |
What causes Nonalcoholic steatohepatitis ? | What causes nonalcoholic steatohepatitis? The underlying cause of NASH remains unclear. It most often occurs in persons who are middle-aged and overweight or obese. Many patients with NASH have elevated blood lipids, such as cholesterol and triglycerides, and many have diabetes or prediabetes. However, not every obese person or every patient with diabetes has NASH. Furthermore, some patients with NASH are not obese, do not have diabetes, and have normal blood cholesterol and lipids. NASH can occur without any apparent risk factor and can even occur in children. While the underlying reason for the liver injury that causes NASH is not known, several factors are possible candidates: insulin resistance release of toxic inflammatory proteins by fat cells (cytokines) oxidative stress (deterioration of cells) inside liver cells | |
How to diagnose Nonalcoholic steatohepatitis ? | How is nonalcoholic steatohepatitis diagnosed? NASH is usually first suspected when elevations are noted in liver tests that are included in routine blood test panels. These may include alanine aminotransferase (ALT) or aspartate aminotransferase (AST). When further evaluation shows no apparent reason for liver disease (such as medications, viral hepatitis, or excessive use of alcohol) and when x-rays or imaging studies of the liver show fat, NASH is suspected. The only way to definitely diagnosis NASH and separate it from simple fatty liver is through a liver biopsy. For a liver biopsy, a needle is inserted through the skin to remove a small piece of the liver. NASH is diagnosed when examination of the tissue with a microscope shows fat along with inflammation and damage to liver cells. If the tissue shows fat without inflammation and damage, simple fatty liver or NAFLD is diagnosed. An important piece of information learned from the biopsy is whether scar tissue has developed in the liver. Blood tests and scans cannot reliably provide this information at this time. | |
What are the treatments for Nonalcoholic steatohepatitis ? | How might nonalcoholic steatohepatitis be treated? Currently, there are no specific therapies for NASH. The most important recommendations given to persons with this disease are to: reduce their weight (if obese or overweight) follow a balanced and healthy diet increase physical activity avoid alcohol avoid unnecessary medications These are standard recommendations, but they can make a difference. They are also helpful for other conditions, such as heart disease, diabetes, and high cholesterol. Individuals with other medical conditions (diabetes, high blood pressure, or elevated cholesterol) should be treated with medication as advised by their physician. Some new treatment options are now being studied in clinical trials. These include the use of antioxidants (such as vitamin E, selenium, and betaine) and some newer antidiabetic medications (metformin, rosiglitazone, and pioglitazone) which treat insulin resistance. | |
What is (are) Ring chromosome 20 ? | Ring chromosome 20 is a chromosome abnormality that affects the development and function of the brain. People with ring chromosome 20 often have recurrent seizures or epilepsy. Other symptoms might include intellectual disability, behavioral difficulties, growth delay, short stature, a small head (microcephaly), and characteristic facial features. Ring chromosome 20 is caused by an abnormal chromosome known as a ring chromosome 20 or r(20). A ring chromosome is a circular structure that occurs when a chromosome breaks in two places and its broken ends fuse together. Ring chromosome 20 is usually not inherited. It almost always occurs by chance during the formation of reproductive cells (eggs or sperm) or in early embryonic development. Treatment for ring chromosome 20 is focused on management of seizures and accommodations for learning. | |
What are the treatments for Ring chromosome 20 ? | How might ring chromosome 20 be treated? Treatment of ring chromosome 20 is typically focused on management of seizures. The seizures associated with ring chromosome 20 do not generally respond well to medications. The treatment that is successful varies from person to person. Broad spectrum AEDs are usually tried first since they are active against different seizure types. This includes valproate, levetiracetam, lamotrigine, topiramate and zonisamide. Success has been reported in some people with a combination of valproate and lamotrigine, but so far no single therapy has worked for everyone. Vagus nerve stimulation (VNS) has been tried and a reduction in seizures has been reported in some cases but not in others. This involves implanting a medical device under the skin, similar to a pacemaker that delivers a mild electrical current to the brain via the vagus nerve. The long-term effectiveness of VNS therapy is not yet known. The ketogenic diet, which is high in fat and low in carbohydrate, has been shown to be helpful in other types of epilepsy. However there are no published reports about whether this is successful or not in ring chromosome 20 epilepsy.

What is (are) Fumarase deficiency ? | Fumarase deficiency is an inherited condition that primarily affects the nervous system, especially the brain. Affected infants may have microcephaly, abnormal brain structure, severe developmental delay, weak muscle tone (hypotonia), failure to thrive, seizures, and/or distinctive facial features. Other signs and symptoms may include hepatosplenomegaly, an excess of red blood cells (polycythemia), and/or or deficiency of white blood cells (leukopenia). Affected individuals usually survive only a few months, but a few have lived into early adulthood. This condition is caused by mutations in the FH gene and is inherited in an autosomal recessive manner. No effective treatment is currently available. | |
What are the symptoms of Fumarase deficiency ? | What are the signs and symptoms of Fumarase deficiency? Most newborns with fumarase deficiency show severe neurologic abnormalities, including poor feeding, failure to thrive, and poor muscle tone (hypotonia). Early-onset infantile encephalopathy (altered brain structure or function), seizures, and severe developmental delay with microcephaly are also common. Other signs and symptoms may include infantile spasms, abnormal posturing of the limbs, and autistic features. Distinctive facial features have been reported in some affected individuals and have included an unusually prominent forehead (frontal bossing); low-set ears; a small jaw (micrognathia); widely-spaced eyes (ocular hypertelorism); depressed nasal bridge; and high-arched palate. Other findings in affected individuals can include neonatal polycythemia (an excess of red blood cells); leukopenia (deficiency of white blood cells); neutropenia; enlarged liver and spleen (hepatosplenomegaly); and pancreatitis. Many children with this condition do not survive infancy or childhood. Those surviving beyond childhood have severe psychomotor deficits.

What causes Fumarase deficiency ? | What causes fumarase deficiency? Mutations in the FH gene cause fumarase deficiency. The FH gene provides instructions for making an enzyme called fumarase, which participates in a series of reactions allowing cells to use oxygen and generate energy. Mutations in the FH gene disrupt the enzyme's ability to do its job. Disruption of the process that generates energy for cells is particularly harmful to cells in the developing brain, thus resulting in the signs and symptoms of fumarase deficiency. | |
What are the treatments for Fumarase deficiency ? | How might fumarase deficiency be treated? There is currently no effective treatment for fumarase deficiency. Nutritional intervention may be appropriate for children with feeding difficulties. Physical therapy and wheelchairs can also be useful for some individuals. | |
What is (are) Cheilitis glandularis ? | Cheilitis glandularis is a rare inflammatory disorder of the lip. It is mainly characterized by swelling of the lip with hyperplasia of the salivary glands; secretion of a clear, thick mucus; and variable inflammation. Enlargement and chronic exposure of the mucous membrane on the lower lip becomes affected by the environment, leading to erosion, ulceration, crusting, and, occasionally, infection. Cheilitis glandularis is more common in adult males, although cases have been described in women and children. In Caucasians, it is associated with a relatively high incidence of squamous cell carcinoma of the lip. Although there may be a genetic susceptibility, no definitive cause has been established. Treatment may include surgical excision by vermilionectomy (sometimes called a lip shave), but treatment varies for each individual. | |

What are the treatments for Cheilitis glandularis ? | How might cheilitis glandularis be treated? The approach to treatment for cheilitis glandularis is typically based on information obtained from histopathologic analysis (microscopic examination of the tissue); the identification of the likely causes responsible for the condition; and attempts to alleviate or eradicate those causes. Given the relatively small number of reported cases of the condition, there is not sufficient or reliable data that exists with regard to medical approaches. Therefore, treatment generally varies accordingly for each individual. For cases attributable to angioedema (swelling similar to hives beneath the skin), an antihistamine may help with temporary reduction of acute, nonpurulent (lacking pus) swelling. Suppurative cases (those with pus present) typically require management with appropriate antimicrobial treatment as determined by culture and sensitivity testing. Concomitant corticosteroid treatment may increase the effectiveness of antimicrobial therapy in cases with nodularity; however, the potential adverse effects of long-term corticosteroid treatment, and because it can promote local fibrosis and scarring, limit its potential use either as an adjunct to antibiotic treatment or as a single therapeutic modality. Topical 5-fluorouracil is useful for treatment of dysplastic actinic cheilitis and to curtail its progression. In conjunction with clinical supervision, it can be prescribed as an alternative to vermilionectomy (sometimes called a lip shave) or as a preventative measure following vermilionectomy. In cheilitis glandularis cases in which a history of chronic sun exposure exists (especially if the individual is fair skinned or the everted lip surface is chronically eroded, ulcerated, or crusted), biopsy is strongly recommended to rule out actinic cheilitis or carcinoma. Surgical excision is typically not necessary when the diagnosis is actinic cheilitis with atypia or only mild dysplasia; however, individuals require ongoing clinical vigilance at regular intervals and instruction in measures to protect the lips from further sun damage. Treatment options for cases of actinic cheilitis with moderate-to-severe dysplasia include surgical stripping or vermilionectomy, cryosurgery or laser surgery, or topical chemotherapy with 5-fluorouracil. Given the potential for recurrence and the risk for development of carcinoma, sun protective measures and regular clinical monitoring should be instituted. In cases in which eversion, extensive fibrosis, and induration have resulted in lip incompetence with functional and cosmetic compromise, chronic pain, and surface disruption, surgical cheiloplasty (lip reduction) may be indicated to restore normal lip architecture and function. Cheiloplasty is also a prophylactic measure for reducing the risk of actinic injury. | |
What is (are) Froelich syndrome ? | Froelich syndrome is characterized by obesity and hypogonadism due to a hypothalamic-pituitary disorder. The hypothalamus is a part of the brain where certain functions such as sleep cycles and body temperature are regulated. The pituitary is a gland that makes hormones that affect growth and the functions of other glands in the body. Froehlich syndrome is acquired (i.e., not thought to be inherited or genetic). This syndrome appears to affect males more commonly. The term 'Froelich syndrome' is rarely used today. | |
What are the symptoms of Froelich syndrome ? | What are the signs and symptoms of Froelich syndrome? Signs and symptoms of Froelich syndrome include obesity, small testes, delay in the onset of puberty, short stature (compared to other family members of the same sex), malformed or undersized fingernails, and headaches. Some children with Froehlich syndrome may have mental retardation, difficulties with vision, and in rare cases diabetes. Other symptoms of the syndrome may include excessive thirst, excessive urination, and very delicate skin. | |
What causes Froelich syndrome ? | What causes Froelich syndrome? Froehlich syndrome is usually caused by lesions in the hypothalamic gland or pituitary gland. The lesions may be caused by a tumor (e.g., craniopharyngioma), swelling from an infection (e.g., tuberculosis), encephalitis, or other brain injuries. | |
How to diagnose Froelich syndrome ? | How might Froelich syndrome be diagnosed? Diagnosis of Froelich syndrome may be difficult and requires cautious and thoughtful clinical examination, testing urine for low levels of pituitary hormones, and likely other additional tests before a definitive diagnosis of Froehlich syndrome can be made. | |

What causes Juvenile primary lateral sclerosis ? | What causes juvenile primary lateral sclerosis? Juvenile primary lateral sclerosis is caused by mutations in the ALS2 gene. The ALS2 gene provides instructions for making a protein called alsin. Alsin is abundant in motor neurons, but its function is not fully understood. Mutations in the ALS2 gene alter the instructions for producing alsin. As a result, alsin is unstable and decays rapidly, or it is disabled and cannot function properly. It is unclear how the loss of functional alsin protein damages motor neurons and causes juvenile primary lateral sclerosis. | |
Is Juvenile primary lateral sclerosis inherited ? | How is juvenile primary lateral sclerosis inherited? Juvenile primary lateral sclerosis 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 is (are) Retroperitoneal fibrosis ? | Retroperitoneal fibrosis is a slowly progressive disorder in which the tubes that carry urine from the kidneys to the bladder (ureters) and other abdominal organs are blocked by a fibrous mass and inflammation in the back of the abdomen. The disorder may cause chronic unilateral obstructive uropathy or chronic bilateral obstructive uropathy. Risk factors for retroperitoneal fibrosis include asbestos exposure, smoking, tumor, infection, trauma, radiotherapy, surgery, and use of certain drugs. | |
What are the symptoms of Retroperitoneal fibrosis ? | What are the symptoms of retroperitoneal fibrosis? Early symptoms of retroperitoneal fibrosis may include: Dull pain in the abdomen that increases with time Swelling of one leg Decreased circulation in the legs leading to pain and discoloration Late symptoms of retroperitoneal fibrosis may include: Decreased urine output Total lack of urine (anuria) Nausea, vomiting, changes in thinking caused by kidney failure and the resulting build-up of toxic chemicals in the blood. Severe abdominal pain with hemorrhage due to ischemic bowel | |
What causes Retroperitoneal fibrosis ? | What causes retroperitoneal fibrosis? The cause of retroperitoneal fibrosis is unknown in many cases (idiopathic). Some cases occur in association with other factors, including: Asbestos exposure Smoking Neoplasms (tumor) Infections Trauma Radiotherapy Surgery Use of certain drugs | |
What are the treatments for Retroperitoneal fibrosis ? | How might retroperitoneal fibrosis be treated? Treatment of retroperitoneal fibrosis may include: Corticosteroid therapy Tamoxifen Surgery Stents Corticosteroids are tried first. Dosing will be prescribed on a case by case basis, but doses often vary between 30 and 60 mg per day. Corticosteroids are then tapered slowly. Some people with retroperitoneal fibrosis may continue on low dose maintenance therapy for up to 2 years. If corticosteroid treatment doesn't work, a biopsy should be done to confirm the diagnosis. Other medicines to suppress the immune system, such as mycophenolate mofetil, methotrexate, azathioprine, cyclophosphamide or tamoxifen can be prescribed alone or in combination with corticosteroids. When medicine does not work, surgery and stents (draining tubes) are considered. Stents (drainage tubes) placed in the ureter or in the renal pelvis may provide short-term relief of the symptoms until the condition is surgically treated. Surgery aims to remove the mass and/or free the ureters. | |
What is (are) Graves' disease ? | Graves' disease is an autoimmune disorder that leads to overactivity of the thyroid gland (hyperthyroidism). It is caused by an abnormal immune system response that causes the thyroid gland to produce too much thyroid hormones. Graves disease is the most common cause of hyperthyroidism and occurs most often in women over age 20. However, the disorder may occur at any age and may affect males as well. Treatment may include radioiodine therapy, antithyroid drugs, and/or thyroid surgery. | |

What is (are) Dyggve-Melchior-Clausen syndrome ? | Dyggve-Melchior-Clausen (DMC) syndrome is a rare, progressive genetic condition characterized by abnormal skeletal development, microcephaly, and intellectual disability. Only about 100 cases have been reported to date. Skeletal abnormalities may include a barrel-shaped chest with a short truck, partial dislocation of the hips, knock knees, bowlegs, and decreased joint mobility. A small number of affected individuals experience instability in the upper neck vertebrae that can lead to spinal cord compression, weakness and paralysis. Normally, there is growth deficiency resulting in short stature. DMC is caused by mutations in the DYM gene and is inherited in an autosomal recessive manner. Some researchers have described an X-linked pattern of inheritance, which has not been confirmed to date. | |
What are the symptoms of Dyggve-Melchior-Clausen syndrome ? | What are the signs and symptoms of Dyggve-Melchior-Clausen syndrome? Affected newborns may be small at birth, but otherwise appear normal. Skeletal findings are often recognized first between 1 and 18 months. With age, other characteristics begin to develop. Chest deformities, feeding difficulties, and developmental delay usually occur before 18 months. Disproportionate short stature usually occurs after 18 months. Additional features may include a long skull, distinctive facial appearance, a protruding jaw, microcephaly, and claw-like hands. Intellectual disability occurs in most cases, ranging from moderate to severe. Affected individuals can also develop a protruding breastbone; spinal abnormalities; abnormal bones in the hands, fingers, toes, wrists, and long bones of the arms and legs; and joint contractures, especially of the elbows and hips. Secondary problems resulting from the skeletal abnormalities may include spinal compression, dislocated hips, and restricted joint mobility. These problems may in turn cause a waddling gait. The Human Phenotype Ontology provides the following list of signs and symptoms for Dyggve-Melchior-Clausen 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.

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. | |
How to diagnose Dyggve-Melchior-Clausen syndrome ? | How is Dyggve-Melchior-Clausen syndrome diagnosed? DMC syndrome may be suspected following a thorough clinical evaluation, a detailed patient history, and identification of characteristic findings (e.g., barrel chest, and disproportionate short stature). Radiographs may confirm specific skeletal abnormalities and findings consistent with DMC syndrome. Genetic testing can also confirm a diagnosis. Is genetic testing available for Dyggve-Melchior-Clausen syndrome? GeneTests lists the name of the laboratory that performs clinical genetic testing for Dyggve-Melchior-Clausen syndrome.

What are the treatments for Dyggve-Melchior-Clausen syndrome ? | How might Dyggve-Melchior-Clausen syndrome be treated? Treatment of individuals with DMC syndrome depends on the affected person's symptoms and is usually supportive. There is no cure for this condition. Treatments might include spinal fusion of the segments of the spinal column at the top of the spine or other means of vertebral stabilization. Additional surgical techniques may be used to correct various skeletal abnormalities such as dislocation of the shoulder and hip joints. In some cases, hip replacement is required. Children with DMC syndrome may benefit from early intervention and special educational programs. | |
What is (are) Prinzmetal's variant angina ? | Prinzmetal's variant angina is characterized by recurrent episodes of chest pain that occur while an individual is at rest. This condition is a form of unstable angina because the episodes do not occur in a predictable pattern. Prinzmetal's variant angina may occur spontaneously, or it may be caused by exposure to cold, emotional stress, alcohol withdrawal, or vasoconstricting medications. The symptoms of this condition usually respond to treatment. Individuals with Prinzmetals' variant angina may have a higher risk for heart attack or arrhythmia. | |
What are the symptoms of Prinzmetal's variant angina ? | What are the symptoms of Prinzmetal's variant angina? The main symptom of Prinzmetal's variant angina is chest pain (angina) with the following characteristics: Occurs under the chest bone Described as squeezing, constricting, tightness, pressure, crushing Is usually severe and may radiate to the neck, jaw, shoulder, or arm Often occurs at rest Typically occurs at the same time each day, usually between midnight and 8am. Duration of pain is 5 to 30 minutes Pain is relieved by nitroglycerin Loss of consciousness |
