What is (are) Transient neonatal diabetes mellitus ? | Transient neonatal diabetes mellitus (TNDB) is a type of diabetes that appears within the first few weeks of life but is transient; affected infants go into remission within a few months, with possible relapse to permanent diabetes in adolescence or adulthood. Affected individuals have slow growth before birth followed by hyperglycemia, dehydration and failure to thrive in infancy. Approximately 70% of cases are caused by the overactivity of certain genes in a region of the long (q) arm of chromosome 6 called 6q24. These cases are referred to as 6q24-related TNDB; most (but not all) of these cases are not inherited. Other genetic causes include mutations in the KCNJ11 and ABCC8 genes, which usually cause permanent neonatal diabetes. Treatment may include rehydration and intravenous insulin at the time of diagnosis, followed by subcutaneous insulin. | |

What is (are) Swyer-James syndrome ? | Swyer-James syndrome is a rare condition in which the lung (or portion of the lung) does not grow normally and is slightly smaller than the opposite lung, usually following bronchiolitis in childhood. It is typically diagnosed after a chest X-ray or CT scan which shows unilateral pulmonary hyperlucency (one lung appearing less dense) and diminished pulmonary arteries. Affected individuals may not have any symptoms, or more commonly, they may have recurrent pulmonary infections and common respiratory symptoms. The cause of the condition is not completely understood. | |
What are the symptoms of Swyer-James syndrome ? | What are the signs and symptoms of Swyer-James syndrome? Individuals with Swyer-James syndrome may not have any symptoms, but affected individuals can have chronic or recurring lung infections, shortness of breath (dyspnea) when performing an activity, coughing up of blood (hemoptysis), and even severe respiratory impairment. | |
What causes Swyer-James syndrome ? | What causes Swyer-James syndrome? The cause of Swyer-James syndrome is not completely understood. Most experts agree that the initial abnormality occurs in the distal bronchi (air tubes that bring air to and from the lungs) after an infection during early childhood. The smaller size of the affected lung may be due to the infection inhibiting the normal growth of the lung. A number of reports have described Swyer-James syndrome following childhood histories including radiation therapy; measles; pertussis (whooping cough); tuberculosis; breathing in a foreign body; mycoplasma; and viral infections, especially adenovirus. Research has suggested that a hyper-immune reaction in the lung (producing an unusual abundance of antibodies) may play a role in sustaining airway damage after the initial infection. Some have argued a pre-existing lung abnormality may predispose individuals to the condition. Although bronchial damage of some kind during childhood is generally considered to play an important role, many affected individuals have had no known history of an airway infection. It is possible that some unknown factors present at birth may contribute to the development of Swyer-James syndrome. | |
What are the treatments for Swyer-James syndrome ? | How might Swyer-James syndrome be treated? Individuals with Swyer-James syndrome reportedly have been treated conservatively in the past. However, although there are few reports published, it has been recognized that surgical treatment should be considered when infections cannot be controlled. There have been reports of affected individuals being treated with pneumonectomy (removal of a lung), lobectomy (removal of one or more lobes of a lung) or segmentectomy (removal of a specific segment). It has been proposed that individuals with Swyer-James syndrome may benefit from lung volume reduction surgery (LVRS), a procedure in which damaged tissue is removed from the lung. LVRS was reportedly performed successfully in an individual with Swyer-James syndrome, and it has been suggested that the procedure could be used for managing the condition in other affected individuals because it has shown to be effective for improving pulmonary function and symptoms. | |

What is (are) Pontocerebellar hypoplasia type 2 ? | Pontocerebellar hypoplasia type 2 (PCH2) is a rare condition that affects the development of the brain. Signs and symptoms vary but may include microcephaly, developmental delay with lack of voluntary motor development, intellectual disability and movement disorders (i.e. chorea, dystonia, and spasticity). Affected people may also experience dysphagia (difficulty swallowing), impaired vision, seizures and an inability to communicate. Children with this condition often pass away prior to age 10 years, although survival beyond age 20 years has been reported. PCH2 is caused by changes (mutations) in the TSEN54, TSEN2, TSEN34, or SEPSECS gene and is inherited in an autosomal recessive manner. Treatment is supportive and based on the signs and symptoms present in each person. | |

What is (are) Acanthoma ? | An acanthoma is a small, reddish bump that usually develops on the skin of an older adult. There are several types of acanthoma, including "acantholytic", "epidermolytic", "clear cell", and "melanoacanthoma". Though most individuals have only one acanthoma, there have been rare reports of individuals who have developed many. The exact cause of acanthoma is not known; it is sometimes called a benign tumor, and sometimes described as the result of inflammation. Acanthomas are not considered dangerous and do not require treatment, but they may be removed for cosmetic reasons or to relieve any associated symptoms. | |
What are the treatments for Acanthoma ? | How might an acanthoma be treated? Acanthomas are considered benign, but treatment may be done for cosmetic reasons or to relieve any associated symptoms. Because acanthomas are quite rare, there are no established guidelines for treatment. Treatment may depend on the type, number, and location of acanthomas. For example, a single acanthoma may be removed by surgery, whereas multiple acanthomas may be treated with cryosurgery or the use of the medication fluorouracil cream. | |

What is (are) Wiedemann-Steiner syndrome ? | Wiedemann-Steiner syndrome is a rare genetic condition characterized by distinctive facial features, hairy elbows, short stature, and intellectual disability. This condition is caused by changes (mutations) in the KMT2A gene (also known as the MLL gene). It is inherited in an autosomal dominant manner. Most cases result from new (de novo) mutations that occur only in an egg or sperm cell, or just after conception. Treatment is symptomatic and supportive and may include special education classes and speech and occupational therapies aimed at increasing motor functioning and language. | |

What is (are) Beriberi ? | Beriberi is a condition that occurs in people who are deficient in thiamine (vitamin B1). There are two major types of beriberi: wet beriberi which affects the cardiovascular system and dry beriberi which affects the nervous system. People with wet beriberi may experience increased heart rate, shortness of breath, and swelling of the lower legs. Signs and symptoms of dry beriberi include difficulty walking; loss of feeling in the hands and/or feet; paralysis of the lower legs; mental confusion; speech difficulty; pain; and/or vomiting. Beriberi is rare in the United States since many foods are now vitamin enriched; however, alcohol abuse, dialysis and taking high doses of diuretics increases the risk of developing the condition. In most cases, beriberi occurs sporadically in people with no family history of the condition. A rare condition known as genetic beriberi is inherited (passed down through families) and is associated with an inability to absorb thiamine from foods. Treatment generally includes thiamine supplementation, given by injection or taken by mouth. | |

What is (are) Split hand split foot malformation autosomal recessive ? | Split hand foot malformation (SHFM) is a type of birth defect that consists of missing digits (fingers and/or toes), a deep cleft down the center of the hand or foot, and fusion of remaining digits. The severity of this condition varies widely among affected individuals. SHFM is sometimes called ectrodactyly; however, this is a nonspecific term used to describe missing digits. SHFM may occur by itself (isolated) or it may be part of a syndrome with abnormalities in other parts of the body. At least six different forms of isolated SHFM have been described. Each type is associated with a different underlying genetic cause. SHFM1 has been linked to chromosome 7, and SHFM2 is linked to the X chromosome. SHFM3 is caused by a duplication of chromosome 10 at position 10q24. Changes (mutations) in the TP63 gene cause SHFM4. SHFM5 is linked to chromosome 2, and SHFM6 is caused by mutations in the WNT10B gene. SHFM may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. | |

What is (are) Hydrops fetalis ? | Hydrops fetalis is a serious condition in which abnormal amounts of fluid build up in two or more body areas of a fetus or newborn. There are two types of hydrops fetalis: immune and nonimmune. Immune hydrops fetalis is a complication of a severe form of Rh incompatibility. Rh compatibility causes massive red blood cell destruction, which leads to several problems, including total body swelling. Severe swelling can interfere with how the body organs work. Nonimmune hydrops fetalis occurs when a disease or medical condition disrupts the body's ability to manage fluid. There are three main causes for this type: heart or lung problems, severe anemia (thalassemia), and genetic defects, including Turner syndrome. The exact cause depends on which form a baby has. | |

What is (are) Adiposis dolorosa ? | Adiposis dolorosa is a rare condition characterized by the growth of multiple, painful, lipomas (benign, fatty tumors). The lipomas may occur anywhere on the body and can cause severe pain. Other symptoms may include weakness, fatigability, and mental disturbances. It usually occurs in obese, post-menopausal women, but it can also occur in men. Adiposa dolorosa is chronic and tends to be progressive. The exact cause is unknown. Most cases are sporadic (not inherited) but a few familial cases with autosomal dominant inheritance have been reported. Treatment may include weight reduction; surgical removal or liposuction of lipomas; and pain management. | |
What are the symptoms of Adiposis dolorosa ? | What are the signs and symptoms of Adiposis dolorosa? Adiposis dolorosa is primarily characterized by the development of muliple, painful lipomas (benign, fatty tumors). It is often associated with obesity; physical weakness and lack of energy; and various other symptoms including depression, confusion, dementia and/or epilepsy (seizures). The lipomas may occur anywhere in the body except the face and neck. The most common sites are the knees, upper thighs, back and upper arms. They may cause joint pain (arthralgia) when they are near the joints. Pain associated with the lipomas can be debilitating; it usually worsens with movement or an increase in body weight. Sparse pubic hair and underarm hair have been reported in some affected people. The condition can also be associated with early congestive heart failure, severe hypothyroidism, joint pain, flushing episodes, tremors, cyanosis, high blood pressure, headaches, and nosebleeds.

What causes Adiposis dolorosa ? | What causes adiposis dolorosa? The exact cause of adiposis dolorosa remains unknown. While possible causes have been suggested, none have been confirmed. These include long-term treatment with high-dose corticosteroids; endocrine system abnormalities; and changes in fatty acid or carbohydrate metabolism. Researchers have also suggested that it could be an autoimmune disorder. Because the condition has rarely occurred in more than one person within a family, it may have a genetic component. However, no specific gene known to be associated with the condition has been identified. It is unknown why adiposis dolorosa usually occurs in people who are overweight or obese, or why the signs and symptoms do not appear until mid-adulthood. | |
Is Adiposis dolorosa inherited ? | Is adiposis dolorosa inherited? Most cases of adiposis dolorosa are sporadic (not inherited). This means that it usually occurs in people with no family history of the condition. Adiposis dolorosa has rarely been reported to occur in more than one family member. In some of these cases, it appears to have been inherited in an autosomal dominant manner. In these cases, when an affected person has children, each child has a 50% (1 in 2) risk to inherit the gene causing the condition. However, no associated genes have been identified. | |
How to diagnose Adiposis dolorosa ? | Is genetic testing available for adiposis dolorosa? Clinical genetic testing for adiposis dolorosa is currently not available. This type of testing is typically only available when a genetic cause for a condition has been established, and the specific gene(s) causing the condition have been identified. Most cases of adiposis dolorosa are sporadic (not inherited) and no genes known to be associated with the condition have been identified. We are also not aware of laboratories currently offering research genetic testing for this condition. | |
What are the treatments for Adiposis dolorosa ? | How might adiposis dolorosa be treated? Management of adiposis dolorosa is difficult and no currently available treatments have led to long-lasting, complete pain reduction. Weight reduction, surgical removal of particularly burdensome lesions, and/or liposuction may be helpful for some people. There is currently no drug known to change the course of the disease. Available treatments mainly focus on alleviating symptoms and may include: prednisone or intravenous lidocaine for pain traditional pain medicines such nonsteroidal anti-inflammatory drugs (which are often inefficient), or acetaminophen combined with an opioid analgesic a cortisone/anesthetic injection for localized pain diuretics for swelling of the fingers Other treatments that have led to some pain reduction in some affected people include methotrexate and infliximab; interferon -2b; calcium-channel modulators; and rapid cycling hypobaric pressure. Adjunctive therapies may include acupuncture, cognitive behavioral therapy, hypnosis, and biofeedback. | |

What is (are) Takayasu arteritis ? | Takayasu arteritis is a condition that causes inflammation of the main blood vessel that carries blood from the heart to the rest of the body (aorta) and its associated branched blood vessels. As a result of the inflammation, the blood vessel walls become thick and make it difficult for blood to flow. Over time, impaired blood flow causes damage to the heart and various other organs of the body. Although the cause remains unknown, Takayasu arteritis appears to be an autoimmune condition, in which cells that fight infection and disease are wrongly targeted against the body's own tissues. | |

What is (are) Human T-cell leukemia virus type 1 ? | Human T-cell leukemia virus, type 1 (HTLV-1) is a retroviral infection that affect the T cells (a type of white blood cell). Although this virus generally causes no signs or symptoms, some affected people may later develop adult T-cell leukemia (ATL), HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) or other medical conditions. HTLV-1 is spread by blood transfusions, sexual contact and sharing needles. It can also be spread from mother to child during birth or breast-feeding. There is no cure or treatment for HTLV-1 and it is considered a lifelong condition; however, most (95%) infected people remain asymptomatic (show no symptoms) throughout life. | |
What are the symptoms of Human T-cell leukemia virus type 1 ? | What are the signs and symptoms of human T-cell leukemia virus, type 1? Human T-cell leukemia virus, type 1 (HTLV-1) generally causes no signs or symptoms. However, some affected people may later develop adult T-cell leukemia (ATL), HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) or other medical conditions. Approximately 2-5% of people with HTLV-1 will develop ATL, a cancer of the T-cells (a type of white blood cell). The signs and symptoms of this condition and the disease progression vary from person to person. Affected people may have the following features: Fatigue Lymphadenopathy (swollen lymph nodes) Thirst Nausea and vomiting Fever Skin and bone abnormalities Enlarged liver and/or spleen Frequent infections Roughly .25-2% of people with HTLV-1 will develop HAM/TSP, a chronic, progressive disease of the nervous system. Signs and symptoms of this condition vary but may include: Progressive weakness Stiff muscles Muscle spasms Backache 'Weak' bladder Constipation | |
What causes Human T-cell leukemia virus type 1 ? | What causes human T-cell leukemia virus, type 1? Human T-cell leukemia virus, type 1 (HTLV-1) occurs when a person is infected by the human T-cell leukemia retrovirus. HTLV-1 is spread by blood transfusions, sexual contact and sharing needles. It can also be spread from mother to child during birth or breast-feeding. It is unclear why some people with HTLV-1 develop adult T-cell leukemia (ATL), HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) or other medical conditions, while others remain asymptomatic (show no signs or symptoms) their entire lives. | |
How to diagnose Human T-cell leukemia virus type 1 ? | How is human T-cell leukemia virus, type 1 diagnosed? Human T-cell leukemia virus, type 1 (HTLV-1) is usually diagnosed based on blood tests that detect antibodies to the virus. However, HTLV-1 is often never suspected or diagnosed since most people (95%) never develop any signs or symptoms of the infection. Diagnosis may occur during screening for blood donation, testing performed due to a family history of the infection, or a work-up for an HTLV-1-associated condition such as adult T-cell leukemia (ATL) or HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP). | |
What are the treatments for Human T-cell leukemia virus type 1 ? | How might human T-cell leukemia virus, type 1 be treated? No cure or treatment exists for human T-cell leukemia virus, type 1 (HTLV-1). Management is focused on early detection and preventing the spread of HTLV-1 to others. Screening blood doners, promoting safe sex and discouraging needle sharing can decrease the number of new infections. Mother-to-child transmission can be reduced by screening pregnant women so infected mothers can avoid breastfeeding. | |
What are the symptoms of Ulnar hypoplasia lobster claw deformity of feet ? | What are the signs and symptoms of Ulnar hypoplasia lobster claw deformity of feet? The Human Phenotype Ontology provides the following list of signs and symptoms for Ulnar hypoplasia lobster claw deformity of feet.

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) Aplasia/Hypoplasia of the radius 90% Split hand 90% Hypoplasia of the ulna - Short finger - Split foot - 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 is (are) Alpha-1 antitrypsin deficiency ? | Alpha-1 antitrypsin deficiency (AATD) is a disorder that causes a deficiency or absence of the alpha-1 antitrypsin (AAT) protein in the blood. AAT is made in the liver and sent through the bloodstream to the lungs, to protect the lungs from damage. Having low levels of ATT (or no ATT) can allow the lungs to become damaged, making breathing hard. Age of onset and severity of AATD can vary based on how much ATT an affected person is missing. In adults, symptoms may include shortness of breath; reduced ability to exercise; wheezing; respiratory infections; fatigue; vision problems; and weight loss. Some people have chronic obstructive pulmonary disease (COPD) or asthma. Liver disease (cirrhosis) may occur in affected children or adults. Rarely, AATD can cause a skin condition called panniculitis. AATD is caused by mutations in the SERPINA1 gene and is inherited in a codominant manner. Treatment is based on each person's symptoms and may include bronchodilators; antibiotics for upper respiratory tract infections; intravenous therapy of AAT; and/or lung transplantation in severe cases. | |

In these cases, the sign or symptom may be rare or common. | |
What causes Alpha-1 antitrypsin deficiency ? | What causes alpha-1 antitrypsin deficiency? Alpha-1 antitrypsin deficiency (AATD) is caused by mutations in the SERPINA1 gene. This gene gives the body instructions to make a protein called alpha-1 antitrypsin (AAT), which protects the body from an enzyme called neutrophil elastase. Neutrophil elastase helps the body fight infections, but it can also attack healthy tissues (especially the lungs) if not controlled by AAT. Mutations that cause AAT can cause a deficiency or absence of AAT, or a form of AAT that does not work well. This allows neutrophil elastase to destroy lung tissue, causing lung disease. In addition, abnormal AAT can build up in the liver and cause damage to the liver. The severity of AATD may also be worsened by environmental factors such as exposure to tobacco smoke, dust, and chemicals. | |
How to diagnose Alpha-1 antitrypsin deficiency ? | How is alpha-1 antitrypsin deficiency diagnosed? Alpha-1 antitrypsin deficiency (AATD) may first be suspected in people with evidence of liver disease at any age, or lung disease (such as emphysema), especially when there is no obvious cause or it is diagnosed at a younger age. Confirming the diagnosis involves a blood test showing a low serum concentration of the alpha-1 antitrypsin (AAT) protein, and either: detecting a functionally deficient AAT protein variant by isoelectric focusing (a method for detecting mutations); or detecting SERPINA1 gene mutations on both copies of the gene with molecular genetic testing. (This confirms the diagnosis when the above-mentioned tests are not performed or their results are not in agreement.) Specialists involved in the diagnosis may include primary care doctors, pulmonologists (lung specialists), and/or hepatologists (liver specialists). | |
What are the treatments for Alpha-1 antitrypsin deficiency ? | How might alpha-1 antitrypsin deficiency be treated? Treatment of alpha-1 antitrypsin deficiency (AATD) depends on the symptoms and severity in each person. COPD and other related lung diseases are typically treated with standard therapy. Bronchodilators and inhaled steroids can help open the airways and make breathing easier. Intravenous augmentation therapy (regular infusion of purified, human AAT to increase AAT concentrations) has been recommended for people with established fixed airflow obstruction (determined by a specific lung function test). This therapy raises the level of the AAT protein in the blood and lungs. Lung transplantation may be an appropriate option for people with end-stage lung disease. Liver transplantation is the definitive treatment for advanced liver disease. When present, panniculitis may resolve on its own or after dapsone or doxycycline therapy. When this therapy does not help, it has responded to intravenous augmentation therapy in higher than usual doses. All people with severe AATD should have pulmonary function tests every 6 to 12 months. Those with ATT serum concentrations 10% to 20% of normal should have periodic evaluation of liver function to detect liver disease. People with established liver disease should have periodic ultrasounds of the liver to monitor for fibrotic changes and liver cancer (hepatocellular carcinoma). Yearly vaccinations against influenza and pneumococcus are recommended to lessen the progression of lung disease. Vaccination against hepatitis A and B is recommended to lessen the risk of liver disease. People with AATD should avoid smoking and occupations with exposure to environmental pollutants. Parents, older and younger siblings, and children of a person with severe AATD should be evaluated to identify as early as possible those who would benefit from treatment and preventive measures. | |
What is (are) Pendred syndrome ? | Pendred syndrome is a condition usually characterized by sensorineural hearing loss in both ears (bilateral) and euthyroid goiter (enlargement of the thyroid gland with normal thyroid gland function). The amount of hearing loss varies among affected people. In many cases, significant hearing loss is present at birth. In other cases, hearing loss does not develop until later in infancy or childhood. Some people have problems with balance caused by dysfunction of the part of the inner ear that helps with balance and orientation (the vestibular system). Pendred syndrome is inherited in an autosomal recessive manner. Mutations in 3 genes are currently known to cause the condition (SLC26A4, FOXI1, and KCNJ10) and are found in about half of affected people. Other genes responsible for the condition have not yet been identified. | |

In these cases, the sign or symptom may be rare or common. | |
Is Pendred syndrome inherited ? | How is Pendred syndrome inherited? Pendred syndrome is inherited in an autosomal recessive manner. For most autosomal recessive conditions, a person must have 2 changed (mutated) copies of the responsible gene in each cell in order to have the condition. One changed copy of the responsible gene is usually inherited from each parent; the parents 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 be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% chance to not be a carrier and not have the condition. Pendred syndrome can be caused either by having mutations in both copies of the SLC26A4 gene (more commonly), or by having one mutation in the SLC26A4 gene and one mutation in another gene. | |
What is (are) Intrahepatic cholestasis of pregnancy ? | Intrahepatic cholestasis of pregnancy (ICP) is a disorder of the liver that occurs in women during pregnancy. Cholestasis is a condition that impairs the release of bile (a digestive juice) from liver cells. The bile then builds up in the liver, impairing liver function. Symptoms typically become apparent in the third trimester of pregnancy and can include severe itching (pruritus). Occasionally, the skin and the whites of the eyes can have a yellow appearance (jaundice). ICP is additionally associated with risks to the developing baby such as premature delivery and stillbirth. The cause of ICP is largely unknown, although approximately 15% of cases are caused by mutations in either the ABCB11 or ABCB4 genes. Mutations within the ABCB11 and ABCB4 genes are inherited in an autosomal dominant manner. Symptoms of ICP are typically limited to pregnancy. Bile flow returns to normal after delivery and the signs and symptoms of the condition disappear, however, they can return during later pregnancies. | |

What causes Intrahepatic cholestasis of pregnancy ? | What causes intrahepatic cholestasis of pregnancy? Largely, the cause of intrahepatic cholestasis of pregnancy (ICP) is unknown. ICP is present in approximately 1% of pregnancies in the United States. It is thought to be caused by a mixture of genetic, hormonal, and environmental factors. Risk factors include: A personal or family history of cholestasis of pregnancy A history of liver disease A multiple gestation pregnancy (twins, triplets, etc) Approximately 15% of women with ICP have a mutation in either the ABCB11 orABCB4 gene. Mutations within these genes increase the likelihood that a woman will develop ICP. Mutations within the ABCB11 and ABCB4 gene(s) are inherited in an autosomal dominant manner. This means that in order to be affected, a person only needs a change 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 within the gene. A person with a mutation in either theABCB11 or ABCB4 gene has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Intrahepatic cholestasis of pregnancy ? | How is intrahepatic cholestasis of pregnancy diagnosed? Intrahepatic cholestasis of pregnancy (ICP) is suspected during pregnancy when symptoms of itching (pruritis) present after 25 weeks of gestation with absence of a rash or underlying maternal liver disease. The diagnosis is typically confirmed with the finding of elevated serum bile acids. Is genetic testing available for intrahepatic cholestasis of pregnancy? In the presence of a family history of intrahepatic cholestasis of pregnancy (ICP) and/or known mutations in either the ABCB11 or ABCB4 genes, genetic testing is available. The Genetic Testing Registry (GTR), a resource from the National Center for Biotechnology, offers a listing of laboratories that perform genetic testing for intrahepatic cholestasis of pregnancy. For more information, click on the link. | |
What are the treatments for Intrahepatic cholestasis of pregnancy ? | How might intrahepatic cholestasis of pregnancy be treated? Treatment for intrahepatic cholestasis of pregnancy aims to relieve itching and prevent complications. Medications utilized to relieve itching might include ursodiol (Actigall, Urso), which helps decrease the level of bile in the mother's bloodstream, relieves itchiness and may reduce complications for the baby. To prevent pregnancy complications, close monitoring of the baby might be recommended. Even if prenatal tests appear normal, induction of early labor might be recommended. | |

What is (are) Childhood hypophosphatasia ? | Childhood hypophosphatasia is a form of hypophosphatasia, a rare condition that affects the bones. Childhood hypophosphatasia, specifically, is generally diagnosed when the condition develops after six months of age but before adulthood. Signs and symptoms vary but may include delayed motor milestones; low bone mineral density for age; early loss of baby teeth (before age 5); bone and joint pain; short stature; a waddling gait; skeletal malformations; and/or unexplained broken bones. The forms of hypophosphatasia that develop during childhood are generally more mild than those that appear in infancy. Childhood hypophosphatasia is caused by changes (mutations) in the ALPL gene and can be inherited in an autosomal dominant or autosomal recessive manner. Treatment is supportive and based on the signs and symptoms present in each person. Recently an enzyme replacement therapy (ERT) called asfotase alfa has been show to improve bone symptoms in people with childhood hypophosphatasia and has been approved by the FDA. | |

What is (are) Amyotrophic lateral sclerosis ? | Amyotrophic lateral sclerosis (ALS), also referred to as "Lou Gehrig's disease," is a progressive motor neuron disease which leads to problems with muscle control and movement. There are various types of ALS, which are distinguished by their signs and symptoms and their cause. Early symptoms may include muscle twitching, cramping, stiffness, or weakness, eventually followed by slurred speech and difficulty chewing or swallowing (dysphagia). As the disease progresses, individuals become weaker are are eventually wheelchair-dependent. Death often results from respiratory failure within 2 to 10 years after the onset of symptoms. Most affected individuals have a sporadic (not inherited) form of ALS; about 5-10% have a familial (inherited) form of the condition. Familial ALS may caused by mutations in any one of several genes and the pattern of inheritance varies depending on the gene involved. Treatment is generally supportive. | |

What causes Amyotrophic lateral sclerosis ? | What causes amyotrophic lateral sclerosis? In approximately 90-95% of cases the cause of amyotrophic lateral sclerosis (ALS) is unknown and is sporadic (occurring in individuals with no history of the condition in the family). The remaining 5-10% of cases are genetic (familial), often occurring in individuals with a family history of the condition. Mutations in any of several genes, including the C9orf72, SOD1, TARDBP, FUS, ANG, ALS2, SETX, and VAPB genes, can cause familial ALS and may contribute to the development of sporadic ALS. About 60% of individuals with familial ALS have an identifiable genetic mutation; the genetic cause in the remaining cases is unknown. The genes associated with ALS appear to play a role in how neurons function or are involved in regulating the production of various proteins. Over the years, various types of environmental exposures have been proposed as possible contributors to the cause of ALS, including mercury, manganese, products used in farming (fertilizers, insecticides, herbicides), and physical and dietary factors. Exposures have been suggested as a possible explanation for the increased incidence of ALS in Gulf War veterans. Further investigation is ongoing. | |
Is Amyotrophic lateral sclerosis inherited ? | Is amyotrophic lateral sclerosis (ALS) inherited? About 90-95% percent of cases of ALS are not inherited and occur in individuals with no history of the condition in their family. The remaining 5-10% of cases are familial, and are thought to be caused by mutations in any one of several genes. The inheritance pattern associated with familial ALS varies depending on the disease-causing gene involved. Most familial cases are inherited in an autosomal dominant manner. This means that only one altered (mutated) copy of the disease-causing gene in each cell is sufficient to cause the condition. In most of these cases, an affected individual has one parent with the condition. When an individual with an autosomal dominant form of ALS has children, each child has a 50% (1 in 2) risk to inherited the mutated copy of the gene and be affected. Less frequently, ALS is inherited in an autosomal recessive manner. In autosomal recessive inheritance, both copies of the disease-causing gene (typically one copy inherited from each parent) must have a mutation for the individual to be affected. The parents of an individual with an autosomal recessive condition, who presumably each 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 the same condition are having 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 parent, and a 25% risk to not have the condition and not be a carrier. Autosomal recessive forms of ALS may be mistaken for non-inherited (sporadic) forms due to having a negative family history of the condition. In rare cases, ALS is inherited in an X-linked dominant manner. This occurs when the disease-causing gene is located on the X chromosome (a sex chromosome). Although females have 2 X chromosomes, having a mutation in one X chromosome is still sufficient to cause the condition. Males who have a mutation (and only one X chromosome) will have the condition. Usually, males with an X-linked dominant form of ALS experience more severe symptoms than females with the same form. Some individuals who do inherit a mutation known to cause ALS never develop signs and symptoms of ALS, although the reason for this is unclear. This phenomenon is referred to as reduced penetrance. | |
How to diagnose Amyotrophic lateral sclerosis ? | Is genetic testing available for amyotrophic lateral sclerosis? Yes. Clinical genetic testing is currently available for several genes in which mutations are known to cause ALS. Genetic testing on a research basis is also available for select susceptibility genes associated with ALS. You can find laboratories offering clinical and research genetic testing for ALS on a Web site called GeneTests. To see GeneTests' list of the types of ALS for which genetic testing is available, click here. Click on "Testing" next to each type of ALS of interest to see a list of the laboratories that offer clinical testing. Click on "Research" next to each type of ALS of interest to see a list of the laboratories that offer research testing. Please note that most of the laboratories listed through GeneTests do not accept direct contact from patients and their families. Therefore, if you are interested in learning more, you will need to work with a health care provider or a genetics professional. | |
What are the treatments for Amyotrophic lateral sclerosis ? | How might amyotrophic lateral sclerosis (ALS) be treated? The Food and Drug Administration (FDA) has approved the first drug treatment for the diseaseriluzole (Rilutek). Riluzole is believed to reduce damage to motor neurons by decreasing the release of glutamate. Clinical trials with ALS patients showed that riluzole prolongs survival by several months, mainly in those with difficulty swallowing. The drug also extends the time before a patient needs ventilation support. Riluzole does not reverse the damage already done to motor neurons, and patients taking the drug must be monitored for liver damage and other possible side effects. Other treatments for ALS are designed to relieve symptoms and improve the quality of life for patients (palliative care). This supportive care is typically provided by multidisciplinary teams of health care professionals such as physicians; pharmacists; physical, occupational, and speech therapists; nutritionists; social workers; and home care and hospice nurses. Working with patients and caregivers, these teams can design an individualized plan of medical and physical therapy and provide special equipment aimed at keeping patients as mobile and comfortable as possible. | |
What is (are) Neonatal intrahepatic cholestasis caused by citrin deficiency ? | Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is a liver condition is also known as neonatal-onset type II citrullinemia. NICCD blocks the flow of bile (a digestive fluid produced by the liver) and prevents the body from processing certain nutrients properly. This leads to transient intrahepatic cholestasis and variable liver dysfunction in children younger than one year of age. NICCD is generally not severe, and symptoms disappear by age one year with appropriate treatment. Years or even decades later, however, some of these individuals develop the characteristic features of adult-onset type II citrullinemia. NICCD is caused by mutations in the SLC25A13 gene. This condition is inherited in an autosomal recessive pattern. | |
What are the symptoms of Neonatal intrahepatic cholestasis caused by citrin deficiency ? | What are the signs and symptoms of Neonatal intrahepatic cholestasis caused by citrin deficiency? Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is characterized by transient intrahepatic cholestasis, diffuse fatty liver, hepatic fibrosis, low birth weight, growth retardation, hypoproteinemia, decreased coagulation factors, hemolytic anemia, hepatomegaly, variable liver dysfunction, and/or hypoglycemia in children younger than one year of age. NICCD is generally not severe, and symptoms typically disappear by age one year with appropriate treatment. At around age two, children with NICCD begin to show a particular fondness for protein-rich and fatty foods and an aversion to sugary and carbohydrate-rich foods. One of more decades later, some of these individuals develop neuropsychiatric symptoms characteristic of adult-onset citrullinemia type II. The Human Phenotype Ontology provides the following list of signs and symptoms for Neonatal intrahepatic cholestasis caused by citrin deficiency. 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) Autosomal recessive inheritance - Cirrhosis - Elevated plasma citrulline - Failure to thrive - Growth delay - Hyperbilirubinemia - Hypercholesterolemia - Hypermethioninemia - Hypertriglyceridemia - Hypoalphalipoproteinemia - Intrahepatic cholestasis - 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 is (are) Monoclonal mast cell activation syndrome ? | Monoclonal mast cell activation syndrome (MMAS) is a rare immunological disorder characterized by recurrent episodes of allergy, flushing, stomach and intestinal cramping, diarrhea, wheezing, fatigue and a temporary loss of consciousness caused by a fall in blood pressure (hypotension). MMAS is very similar to systemic mastocytosis but without the itchy skin patches known as urticaria pigmentosa. Symptoms may be triggered by a number of factors, including eating, exertion, environmental conditions, emotional stress, or insect stings. It is caused by a very small change (mutation) in the KIT gene which results in a defect of the mast cells. Treatment may include antihistamines and other medications, as needed. | |

What is (are) Hypoplastic left heart syndrome ? | Hypoplastic left heart syndrome (HLHS) is a problem with the hearts structure that is present at birth (congenital). It occurs when parts of the left side of the heart (mitral valve, left ventricle, aortic valve, and aorta) do not develop completely. The underdeveloped left side of the heart is unable to provide enough blood flow to the body, which decreases the oxygen-rich blood supply. Babies with HLHS might look normal at birth, but will develop symptoms of HLHS within a few days. These symptoms might include: poor feeding, problems breathing, pounding heart, weak pulse, and ashen or bluish skin color. The cause of HLHs is presently unknown. | |
What are the symptoms of Hypoplastic left heart syndrome ? | What are the signs and symptoms of Hypoplastic left heart syndrome? Normally, oxygen-poor blood is pumped through the right side of the heart to the lungs, where it gains oxygen and returns to the left side of the heart. The oxygen-rich blood is then pumped from the left side of the heart to the rest of the body. At birth, all babies also have two connections, or shunts, between the two sides of the heart; however, within a few days of birth these connections close. In those with HLHS, the underdeveloped left side of the heart is unable to provide enough blood flow to the body. The normal shunts present at birth help to direct blood to the body; when these connections close the oxygen-rich blood supply decreases. At first, a newborn with HLHS may appear normal. Symptoms usually occur in the first few hours of life, although it may take up to a few days to develop symptoms. These symptoms may include: Bluish (cyanosis) or poor skin color Cold hands and feet (extremities) Lethargy Poor pulse Poor suckling and feeding Pounding heart Rapid breathing Shortness of breath In healthy newborns, bluish color in the hands and feet is a response to cold (this reaction is called peripheral cyanosis). However, a bluish color in the chest or abdomen, lips, and tongue is abnormal (called central cyanosis). It is a sign that there is not enough oxygen in the blood. Central cyanosis often increases with crying. The Human Phenotype Ontology provides the following list of signs and symptoms for Hypoplastic left heart 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.

What are the treatments for Hypoplastic left heart syndrome ? | How might hypoplastic left heart syndrome (HLHS) be treated? Once the diagnosis of HLHS is made, the baby will be admitted to the neonatal intensive care unit. A breathing machine (ventilator) may be needed to help the baby breathe. A medicine called prostaglandin E1 is used to keep blood circulating to the body by keeping the ductus arteriosus open. These measures do not solve the problem and ultimately, the baby will require surgery. The first surgery, called the Norwood operation, occurs within the baby's first few days of life. Stage I of the Norwood procedure consists of building a new aorta by: Using the pulmonary valve and artery Connecting the hypoplastic old aorta and coronary arteries to the new aorta Removing the wall between the atria (atrial septum) Making an artificial connection from either the right ventricle or a body-wide artery to the pulmonary artery to maintain blood flow to the lungs (called a shunt) Afterwards, the baby usually goes home. The child will need to take daily medicines and be closely followed by a pediatric cardiologist, who will determine when the second stage of surgery should be done. Stage II of the operation is called the Glenn shunt or hemi-Fontan procedure. This procedure connects the major vein carrying blue blood from the top half of the body (the superior vena cava) directly to blood vessels to the lungs (pulmonary arteries) to get oxygen. The surgery is usually done when the child is 4 to 6 months of age. During stages I and II, the child may still appear somewhat blue (cyanotic).Stage III, the final step, is called the Fontan procedure. The rest of the veins that carry blue blood from the body (the inferior vena cava) are connected directly to the blood vessels to the lungs. The right ventricle now serves only as the pumping chamber for the body (no longer the lungs and the body). This surgery is usually performed when the baby is 18 months - 3 years old. After this final step, the baby is no longer blue. Some patients may need more surgeries in their 20s or 30s if they develop hard to control arrhythmias or other complications of the Fontan procedure. In some hospitals, heart transplantation is considered a better choice than the three-step surgery process. However, there are few donated hearts available for small infants. | |
What is (are) Juvenile-onset dystonia ? | Juvenile-onset dystonia is a form of dystonia, which is a movement disorder characterized by involuntary muscle contractions that cause repetitive movements and/or abnormal postures. The severity and frequency of the movements vary significantly; in some affected people, they may be barely noticeable while in others, the movements are severely disabling and painful. Dystonia can affect just one muscle, a group of muscles or all muscles of the body. Other signs and symptoms of the condition may include a tremor or other neurologic features. In juvenile-onset dystonia, specifically, affected people develop features of the condition between the ages of 13 and 20 years. The underlying cause of juvenile-onset dystonia is poorly understood in most cases. Changes (mutations) in the ACTB gene that are inherited in an autosomal dominant manner have been identified in some families with the condition. Treatment is based on the signs and symptoms present in each person and may include medications, surgery, physical therapy, and other treatments to reduce or eliminate muscle spasms and pain. | |

What is (are) Meningioma ? | Meningiomas originate in the meninges, the membranes that surround the brain and spinal cord. Most meningiomas are benign, though a minority of meningiomas can be classified as atypical or malignant. Though rare, malignant meningiomas can be highly aggressive. However, even benign meningiomas can cause problems if their growth affects the neighboring areas of the brain. Though most meningiomas grow slowly, there is no way to predict the rate of growth for a particular meningioma or to know how long a specific meningioma was growing before it was diagnosed. Signs and symptoms can vary but may include seizures, headaches, weakness in the arms and legs, and vision loss. Sometimes memory loss, carelessness, and unsteadiness are the only symptoms. | |
What are the treatments for Meningioma ? | How might meningiomas be treated? The treatment varies depending on the location of the meningioma and the symptoms caused by the tumor. Careful observation is sometimes the best course of action for people with a meningioma. When treatment is necessary, surgery and radiation are the most common forms of treatment. Radiation may be used if the meningioma cannot be operated on or if the meningioma is only partially removed by surgery. Radiation may also be used in cases of malignant, atypical, or recurrent tumors. Other treatments that have been tried or are being explored include hydroxyurea, epidermal growth factor receptor inhibitors, platelet-derived growth factor receptor inhibitors, vascular endothelial growth factor inhibitors, immunotherapy to stimulate the immune system, and somatostatin analogs which prevent the release of growth hormones. | |
What is (are) KBG syndrome ? | KBG syndrome is a rare condition characterized mainly by skeletal abnormalities, distinctive facial features, and intellectual disability. Specific signs and symptoms may include delayed bone age; abnormalities of the bones of the spine, ribs, and/or hands; large teeth (macrodontia); short stature; developmental delay; and behavioral or emotional issues. Less common features may include hearing loss, seizures, and congenital heart defects. In some cases, KBG syndrome is caused by a mutation in the ANKRD11 gene and is inherited in an autosomal dominant manner. In other cases, the genetic cause is unclear. Some affected people inherit the condition from a parent, while in other people it occurs sporadically. | |
What are the symptoms of KBG syndrome ? | What are the signs and symptoms of KBG syndrome? KBG syndrome is often characterized by distinctive facial features, skeletal abnormalities, short stature, large upper teeth (macrodontia), and developmental delay or intellectual disability. However, the number and severity of symptoms can vary. Characteristic features of the head and face may include a wide, short skull (brachycephaly); triangular face shape; widely spaced eyes (hypertelorism); wide eyebrows that may connect (synophrys); prominent nasal bridge; a long space between the nose and upper lip; and a thin upper lip. In addition to macrodontia, affected people may have jagged or misaligned teeth and/or other abnormalities of the bones or sockets of the jaw. Skeletal abnormalities most often affect the limbs, spine, and/or ribs. Affected people often have delayed bone age. Other signs and symptoms that have been less commonly reported include seizures; syndactyly; a webbed, short neck; undescended testes (cryptorchidism); hearing loss; defects of the palate (roof of the mouth); strabismus; and congenital heart defects.

What is (are) Familial atrial fibrillation ? | Familial atrial fibrillation is an inherited heart condition that disrupts the heart's rhythm. It is characterized by erratic electrical activity in the heart's upper chambers (the atria), causing an irregular response in the heart's lower chambers (the ventricles). This causes a fast and irregular heartbeat (arrhythmia). Signs and symptoms may include dizziness, chest pain, palpitations, shortness of breath, or fainting. Affected people also have an increased risk of stroke and sudden death. While complications may occur at any age, some affected people never have associated health problems. Familial atrial fibrillation may be caused by changes (mutations) in any of various genes, some of which have not been identified. It is most often inherited in an autosomal dominant manner, but autosomal recessive inheritance has been reported. | |

What are the treatments for Familial atrial fibrillation ? | How might familial atrial fibrillation be treated? We are unaware of treatment recommendations specific to familial atrial fibrillation, but there is information available about treatment for atrial fibrillation in general. Treatment for atrial fibrillation depends on the frequency and severity of symptoms and may involve medications, medical procedures, and lifestyle changes. People who don't have symptoms or related heart problems may not need treatment. The main goals of treatment include: Preventing blot clots and lowering risk of stroke. This may involve blood-thinning medications such as warfarin, dabigatran, heparin, and aspirin. Controlling the rate of contractions of the ventricles (rate control). This may involve medications to restore the heart rate to a normal level, such as beta blockers, calcium channel blockers, and digitalis. Restoring a normal heart rhythm (rhythm control). This is typically for people who don't do well with rate control treatment, or for people who recently began having symptoms. Rhythm control may involve medications or procedures and is usually begun in a hospital for monitoring. Procedures may include cardioversion, catheter ablation, or maze surgery. | |

What is (are) Linear scleroderma ? | Linear scleroderma is one sub-type of localized scleroderma, most commonly occurring in childhood. It is characterized by abnormalities of the skin and subcutaneous tissues that often follow a dermatomal distribution and that are found on one side of the body. Besides the lesion in the face or scalp there are also abnormalities of the muscles, fat tissue and skull. When the face is affected, some strips located on the forehead may be hollow and lead to an appearance termed "en coup de sabre". In most cases, Raynaud's phenomenon is absent. The exact cause is still unknown but may be related to an autoimmune reaction resulting in too much collagen. Management is symptomatic and includes immunosupressant medication. Physical therapy is helpful for the muscle retraction problems. | |
What is (are) Hemifacial microsomia ? | Hemifacial microsomia (HFM) is a condition in which part of one side of the face is underdeveloped and does not grow normally. The eye, cheekbone, lower jaw, facial nerves, muscles, and neck may be affected. Other findings may include hearing loss from underdevelopment of the middle ear; a small tongue; and macrostomia (large mouth). HFM is the second most common facial birth defect after clefts. The cause of HFM in most cases is unknown. It usually occurs in people with no family history of HFM, but it is inherited in some cases. Treatment depends on age and the specific features and symptoms in each person. | |

What causes Hemifacial microsomia ? | What causes hemifacial microsomia? For most people with hemifacial microsomia, the cause is unknown. It is believed that something occurs in the early stages of development, such as a disturbance of the blood supply to the first and second branchial arches in the first 6 to 8 weeks of pregnancy. Studies have suggested multiple possible risk factors for hemifacial microsomia. Environmental risk factors include the use of medications during pregnancy such as Accutane, pseudoephedrine, aspirin, or ibuprofen. Other environmental factors include second trimester bleeding, maternal diabetes, being pregnant with multiples, or the use of assisted reproductive technology. A genetic cause is found in some families, such as a chromosome disorder or a genetic syndrome.

It is also possible that a combination of genetic changes and environmental risk factors could cause hemifacial microsomia. |
