What causes Progressive transformation of germinal centers ? | What causes progressive transformation of germinal centers? Is it genetic? The cause of progressive transformation of germinal centers (PTGC) is currently unknown. Also, there is no evidence in the medical literature that PTGC is a genetic condition. | |
What are the treatments for Progressive transformation of germinal centers ? | What treatment is available for progressive transformation of germinal centers? Because progressive transformation of germinal centers (PTGC) is considered a benign condition and usually has no symptoms other than the enlarged lymph node, no treatment is necessary. The enlarged lymph node may stay the same size or shrink over time. Affected individuals should have regular follow-up visits with their physician; a biopsy should be taken of any new enlarged lymph node because PTGC is associated with Hodgkin lymphoma in some individuals. | |

What is (are) Familial osteochondritis dissecans ? | Osteochondritis dissecans is a joint condition that occurs when a piece of cartilage and the thin layer of bone beneath it, separates from the end of the bone. If the piece of cartilage and bone remain close to where they detached, they may not cause any symptoms. However, affected people may experience pain, weakness and/or decreased range of motion in the affected joint if the cartilage and bone travel into the joint space. Although osteochondritis dissecans can affect people of all ages, it is most commonly diagnosed in people between the ages of 10 and 20 years. In most cases, the exact underlying cause is unknown. Rarely, the condition can affect more than one family member (called familial osteochondritis dissecans); in these cases, osteochondritis dissecans is caused by changes (mutations) in the ACAN gene and is inherited in an autosomal dominant manner. Treatment for the condition varies depending on many factors, including the age of the affected person and the severity of the symptoms, but may include rest; casting or splinting; surgery and/or physical therapy. | |

What causes Familial osteochondritis dissecans ? | What causes osteochondritis dissecans? In most cases, the exact underlying cause of osteochondritis dissecans is not completely understood. Scientists suspect that it may be due to decreased blood flow to the end of the affected bone, which may occur when repetitive episodes of minor injury and/or stress damage a bone overtime. In some families, osteochondritis dissecans is caused by changes (mutations) in the ACAN gene. In these cases, which are referred to as familial osteochondritis dissecans, the condition generally affects multiple joints and is also associated with short stature and early-onset osteoarthritis. The ACAN gene encodes a protein that is important to the structure of cartilage. Mutations in this gene weaken cartilage, which leads to the various signs and symptoms of familial osteochondritis disssecans. | |
How to diagnose Familial osteochondritis dissecans ? | How is osteochondritis dissecans diagnosed? A diagnosis of osteochondritis dissecans is usually suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. These test may include x-rays, magnetic resonance imaging (MRI) and/or computed tomography (CT scan). For more information about the diagnosis of osteochondritis dissecans, please click here. | |
What are the treatments for Familial osteochondritis dissecans ? | How might osteochondritis dissecans be treated? The primary aim of treatment for osteochondritis dissecans is to restore normal function of the affected joint, relieve pain and prevent osteoarthritis. Treatment for the condition varies depending on many factors including the age of the affected person and the severity of the symptoms. In children and young teens, osteochondritis dissecans often heals overtime without surgical treatment. These cases are often managed with rest and in some cases, crutches and/or splinting to relieve pain and swelling. If non-surgical treatments are not successful or the case is particularly severe (i.e. the cartilage and bone are moving around within the joint space), surgery may be recommended. Following surgery, physical therapy is often necessary to improve the strength and range of motion of the affected joint. | |
What is (are) Isobutyryl-CoA dehydrogenase deficiency ? | Isobutyryl-CoA dehydrogenase deficiency (IBD deficiency) is an inborn error of valine (an amino acid) metabolism. The symptoms, which may not develop until later in infancy or childhood, can include failure to thrive, dilated cardiomyopathy, seizures, and anemia. IBD deficiency is caused by mutations in the ACAD8 gene. It is inherited in an autosomal recessive manner. | |
What are the symptoms of Isobutyryl-CoA dehydrogenase deficiency ? | What are the signs and symptoms of Isobutyryl-CoA dehydrogenase deficiency? Infants with IBD deficiency usually appear healthy at birth. The signs and symptoms of IBD deficiency may not appear until later in infancy or childhood and can include poor feeding and growth (failure to thrive), a weakened and enlarged heart (dilated cardiomyopathy), seizures, and low numbers of red blood cells (anemia). Another feature of this disorder may be very low blood levels of carnitine (a natural substance that helps convert certain foods into energy). IBD deficiency may be worsened by long periods without food (fasting) or infections that increase the body's demand for energy. Some individuals with gene mutations that can cause IBD deficiency may never experience any signs and symptoms of the disorder. The Human Phenotype Ontology provides the following list of signs and symptoms for Isobutyryl-CoA dehydrogenase deficiency. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Isobutyryl-CoA dehydrogenase deficiency ? | What causes isobutyryl-CoA dehydrogenase deficiency (IBD deficiency)? IBD deficiency is caused by mutations in the ACAD8 gene. The ACAD8 gene provides instructions for making an enzyme that plays an essential role in breaking down proteins from the diet. Specifically, the enzyme is responsible for processing valine, an amino acid that is part of many proteins. If a mutation in the ACAD8 gene reduces or eliminates the activity of this enzyme, the body is unable to break down valine properly. As a result, poor growth and reduced energy production may occur. | |
Is Isobutyryl-CoA dehydrogenase deficiency inherited ? | How is isobutyryl-CoA dehydrogenase deficiency (IBD deficiency) inherited? IBD deficiency is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. | |
What are the treatments for Isobutyryl-CoA dehydrogenase deficiency ? | How is isobutyryl-CoA dehydrogenase deficiency (IBD deficiency) treated? There is no standard treatment protocol for IBD deficiency. Infants diagnosed through newborn screening are encouraged to work with a metabolic disease specialist and a dietician experienced in metabolic disorders. Some treatments may be recommended even if no symptoms have been observed. Treatment may be needed throughout life. The following treatments may be recommended for some babies and children with IBD deficiency. Children with IBD deficiency may be helped by taking L-carnitine, a safe and natural substance which helps the body's cells make energy and get rid of harmful wastes. L-carnitine may also help to prevent or treat the heart problems and anemia seen in children with IBD deficiency. Children with IBD deficiency are advised to avoid fasting. Going without food for a long time causes the body to use its stores of fat and protein for energy. In some people with IBD deficiency, this may lead to the build up of harmful substances in the blood. Eating frequently (every 4 to 6 hours) may help to avoid these health effects. While most children with IBD deficiency do fine without a change in diet, a low-valine food plan might be necessary. Valine is found in all foods with protein. Foods high in valine, such as dairy products, meat, poultry, fish, eggs, dried beans and legumes, nuts and peanut butter should be limited. There are medical foods such low-protein flours, pastas, rice, and special formulas that are made especially for people with organic acid disorders. Your dietician / physician can advise you on whether you should use these foods to supplement your childs diet. | |

What is (are) Senior Loken Syndrome ? | Senior Loken syndrome is a rare disorder characterized by the combination of two specific features: a kidney condition called nephronophthisis and an eye condition known as Leber congenital amaurosis. It can be caused by mutations in one of at least six genes. The proteins produced from these genes are known or suspected to play roles in cell structures called cilia. These microscopic, finger-like projections stick out on the surface of cells and are involved in signaling pathways that transmit information between cells. Cilia are important for the structure and function of many types of cells, including certain cells in the kidneys. They are also necessary for the perception of sensory input (such as vision, hearing, and smell). Senior Loken syndrome is inherited in an autosomal recessive pattern. | |

What is (are) Zika virus infection ? | Zika virus infection is spread to people primarily through the bite of an infected mosquito. Zika virus can also be spread from a pregnant mother to her child and through sexual contact with an affected male partner. Cases of Zika virus transmission via blood transfusions have also been reported. Zika virus outbreaks are currently occurring in many countries. Within the continental United States, Zika virus infections have mostly been in returning travelers. The illness associated with Zika virus infection is usually mild, with symptoms lasting for several days to a week. The most common symptoms of Zika are fever, rash, joint pain, and conjunctivitis (red eyes). However, recent research has suggested a link between Zika virus infection and Guillain-Barre syndrome (GBS). In addition, prenatal Zika virus infection has been shown to cause adverse pregnancy outcomes, including microcephaly and other serious brain anomalies. The precise risk of an adverse pregnancy outcome for a woman infected with Zika virus during pregnancy and the full spectrum of associated birth defects has not yet been determined. No vaccine currently exists to prevent Zika virus infection, but there are still ways to protect oneself. The CDC recommends that pregnant women consider postponing travel to Zika-affected areas. People living in or traveling to areas where Zika virus is found should take steps to prevent mosquito bites. Men who live in or who have traveled to Zika-affected areas can also take steps to prevent sexual transmission of the Zika virus. | |
What are the treatments for Zika virus infection ? | How might a Zika virus infection be treated? There is no vaccine to prevent Zika virus infections, nor is there a specific medicine to treat Zika. Individuals infected with the Zika virus should get plenty of rest, drink fluids, and take medications such as acetaminophen for pain. Aspirin and other nonsteroidal anti-inflammatory medications (NSAIDS) should be avoided until dengue has been ruled out. In pregnant women with evidence of Zika virus in the blood or amniotic fluid, serial ultrasounds should be considered to monitor fetal anatomy and growth every 3-4 weeks. Referral to a maternal-fetal medicine specialist or infectious disease specialist with expertise in pregnancy management is recommended. | |
What is (are) Meningoencephalocele ? | Meningoencephalocele is a type of encephalocele, which is an abnormal sac of fluid, brain tissue, and meninges (membranes that cover the brain and spinal cord) that extends through a defect in the skull. There are two main types of meningoencephalocele, which are named according to the location of the sac. The frontoethmoidal type is located at the frontal and ethmoid bones while the occipital type is located at the occipital bone. Hydrocephalus, abnormalities of the eyeball and tear duct, and other findings have been associated with the condition. Some affected individuals have intellectual or physical disabilities while others have normal development and abilities. The condition is typically congenital (present at birth) but has been reported to develop by chance in older individuals in rare cases. The underlying cause of the condition is uncertain, but environmental factors are thought to play a role. Treatment depends on the size, location and severity of the defect but mainly includes magnetic resonance imaging (MRI) to determine the severity of the defect, followed by surgery to repair it. | |
What causes Meningoencephalocele ? | What causes meningoencephalocele? The exact cause of meningoencephalocele is not known. Some studies have suggested that environmental factors could play a role in causing the condition. Exposure during pregnancy to aflatoxins, toxins produced by a mold that grows in nuts, seeds, and legumes, has been proposed to be a possible cause in some cases. However, its potential role in causing the condition is unclear. It has also been suggested that folate deficiency during pregnancy might play a role, because the condition is so closely related to spina bifida, which can be caused by folate deficiency. However, there have been no studies regarding the relationship of maternal folate deficiency and meningoencephalocele. Further studies are needed to to clarify what may cause the condition. | |
Is Meningoencephalocele inherited ? | Is meningoencephalocele inherited? Meningoencephalocele is not thought to be an inherited condition. Studies have proposed that meningoencephalocele is likely a multifactorial defect. This means that both environmental factors and multiple genes may interact with each other to cause the condition. Studies have suggested that environmental factors probably play an important role. This information is supported by the fact that several studies have not identified the condition among close relatives of affected individuals. To date, there have been no genes identified that are likely to play a strong part in causing the condition. | |
What is (are) Congenital sucrase-isomaltase deficiency ? | Congenital sucrase-isomaltase deficiency (CSID) is a genetic condition that affects a person's ability to digest certain sugars. People with this condition cannot break down the sugars sucrose (a sugar found in fruits, and also known as table sugar) and maltose (the sugar found in grains). CSID usually becomes apparent after an infant begins to consume fruits, juices, and grains. After ingestion of sucrose or maltose, an affected child will typically experience stomach cramps, bloating, excess gas production, and diarrhea. These digestive problems can lead to failure to thrive and malnutrition. Most affected children are better able to tolerate sucrose and maltose as they get older. CSID is inherited in an autosomal recessive pattern and is caused by mutations in the SI gene. | |
What are the symptoms of Congenital sucrase-isomaltase deficiency ? | What are the signs and symptoms of Congenital sucrase-isomaltase deficiency? Affected infants usually develop symptoms soon after they first ingest sucrose, which is found in modified milk formulas, fruits, or starches. Symptoms may include explosive, watery diarrhea resulting in abnormally low levels of body fluids (dehydration), abdominal swelling (distension), and/or abdominal discomfort. In addition, some affected infants may experience malnutrition, resulting from malabsorption of essential nutrients, and/or failure to thrive, resulting from nutritional deficiencies. In some cases, individuals may exhibit irritability; colic; abrasion and/or irritation (excoriation) of the skin on the buttocks as a result of prolonged diarrhea episodes; and/or vomiting. Symptoms of this disorder vary among affected individuals, but are usually more severe in infants and young children than in adults. Symptoms exhibited in infants and young children are usually more pronounced than those of the affected adults because the diet of younger individuals often includes a higher carbohydrate intake. In addition, the time it takes for intestinal digestion is less in infants or young children. The Human Phenotype Ontology provides the following list of signs and symptoms for Congenital sucrase-isomaltase 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) Abnormality of metabolism/homeostasis - Autosomal recessive inheritance - Diarrhea - Malabsorption - Nephrolithiasis - 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. | |
How to diagnose Congenital sucrase-isomaltase deficiency ? | How is congenital sucrase-isomaltase deficiency (CSID) diagnosed? CSID can be diagnosed through clinical evaluation, detailed patient history, and tolerance lab tests. Blood tests can be done to look for a flat serum glucose curve after patients are given a dose of sucrose. In addition, blood and urine samples may test positive for sucrose, maltose, or palatinose (a form of maltose) if used during tolerance testing. The feces may also show sucrose, glucose, and fructose, and an acid pH level of below 5.0 or 6.0. CSID can be confirmed by taking a small sample of tissue (biopsy) from the small intestine and measuring the activity of the enzyme called sucrase-isomaltase. Other tests may include a sucrose hydrogen breath test in which an abnormally high level of hydrogen will be detected in the breath of an affected individual after sucrose ingestion. | |
What are the treatments for Congenital sucrase-isomaltase deficiency ? | How might congenital sucrase-isomaltase deficiency (CSID) be treated? CSID is typically treated by modifying a person's diet to reduce the amount of sucrose. Because many foods contain sucrose and other complex sugars, it can be difficult to completely remove sucrase from the diet. Sucraid is an oral medication containing the enzyme that does not work properly in people with this condition. By taking this medication, those with CSID can eat sucrose-containing foods because this enzyme will break down sucrose. This medication must be taken with each meal or snack. | |

What is (are) Mucolipidosis type 4 ? | Mucolipidosis type 4 is a metabolic condition that affects the body's ability to process certain carbohydrates and fats. As a result, these materials accumulate in cells leading to the various signs and symptoms of the condition. Most people with mucolipidosis type 4 develop severe psychomotor (mental and motor skills) delay by the end of the first year of life and visual impairment that worsens over time. Other common features of the condition include limited or absent speech; intellectual disability; hypotonia that gradually progresses to spasticity; problems controlling hand movements; impaired production of stomach acids; and iron deficiency. Approximately 5% of affected people have a mild form of the condition (known as atypical mucolipidosis type 4) which is associated with milder psychomotor delay and less severe eye abnormalities. Mucolipidosis type 4 is caused by changes (mutations) in the MCOLN1 gene and is inherited in an autosomal recessive manner. Treatment is based on the signs and symptoms present in each person. | |

What is (are) Gorham's disease ? | Gorham's disease is a rare bone disorder that is characterized by bone loss (osteolysis), often associated with swelling or abnormal blood vessel growth (angiomatous proliferation). Bone loss can occur in just one bone, or spread to soft tissue and adjacent bones. It may affect any part of the skeleton, but most commonly involves the skull, shoulder, and pelvis. The cause of Gorham's disease is currently unknown. Most cases occur randomly. Treatment is based on the signs and symptoms present in each affected person, and most commonly involves surgery and/or radiation therapy. In some cases, Gorham's disease improves without treatment (spontaneous remission). | |
What are the symptoms of Gorham's disease ? | What are the signs and symptoms of Gorham's disease? Most cases of Gorham's disease are discovered before the age of 40. Symptoms vary among affected people and depend on the area of the body involved. The most commonly involved sites are the skull, jaw, shoulder, rib cage, and pelvis. The degree of complications ranges from mild to severe, or even life-threatening. In some cases, affected people may rapidly develop pain and swelling in the affected area, or a fracture on the affected site. Others may experience a dull pain or ache, limitation of motion, or generalized weakness that builds over time. Some people don't have any symptoms. Complications from Gorham's disease may occur when fluids build-up in the space between the membrane that surround each lung and line the chest cavity (pleural effusion). This can have serious consequences, including loss of protein, malnutrition, and respiratory distress and failure. The Human Phenotype Ontology provides the following list of signs and symptoms for Gorham's disease. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What are the treatments for Gorham's disease ? | How might Gorham disease be treated? No specific therapy exists for people with Gorham's disease. Certain treatments may be effective in some, but not others. Several different methods are often used before finding one that is effective. In some cases, treatment may not be necessary. Most people require intense treatment, especially if the disease has spread to other areas of the body or if there is extensive involvement in the spine and skull. Treatment options include radiation therapy, steroids, and/or surgery that may involve bone grafting. Other treatments might include biphosphonates (such as pamidronate or zoledronic acid) and alpha-2b interferon. These treatments have led to improvement of symptoms in some cases. More research is necessary to determine the long-term safety and effectiveness of these therapies in people with Gorham's disease. All treatments (pharmacological and surgical) are all still considered to be experimental since there have been no studies done to examine the effectiveness of anything used to date. In general, no single treatment has been proven effective in stopping the progression of the disease. | |

What is (are) Cornelia de Lange syndrome ? | Cornelia de Lange syndrome (CdLS) is a developmental disorder that affects many parts of the body. The severity of the condition and the associated signs and symptoms can vary widely, but may include distinctive facial characteristics, growth delays, intellectual disability and limb defects. Approximately 65% of people affected by CdLS have a change (mutation) in the NIPBL gene. Another 5% of cases are caused by mutations in one of four known genes: SMC1A, SMC3, HDAC8 and RAD21. In the remaining 30% of cases, the underlying genetic cause of the condition is unknown. CdLS can be inherited in an autosomal dominant (NIPBL, SMC2, or RAD21) or X-linked (SMC1A or HDAC8) manner. However, most cases result from new (de novo) mutations and occur in people with no family history of the condition. Treatment is based on the signs and symptoms present in each person. | |

What causes Cornelia de Lange syndrome ? | What causes Cornelia de Lange syndrome? Most cases (approximately 65%) of Cornelia de Lange syndrome (CdLS) are caused by changes (mutations) in the NIPBL gene. An additional 5% of people affected by the condition have mutations in one of four known genes (SMC1A, SMC3, HDAC8 and RAD21). Many of the genes associated with CdLS encode proteins that play an important role in human development before birth. Mutations in these genes may result in an abnormal protein that is not able to carry out its normal function. This is thought to interfere with early development leading to the many signs and symptoms of CdLS. In 30% of people with CdLS, the underlying genetic cause of the condition is unknown. | |
Is Cornelia de Lange syndrome inherited ? | Is Cornelia de Lange syndrome inherited? Cornelia de Lange syndrome (CdLS) can be inherited in an autosomal dominant (NIPBL, SMC2, or RAD21) or X-linked (SMC1A or HDAC8) manner depending on the underlying genetic cause. However, most cases (more than 99%) result from new (de novo) mutations and occur in people with no family history of the condition. | |
How to diagnose Cornelia de Lange syndrome ? | How is Cornelia de Lange syndrome diagnosed? A diagnosis of Cornelia de Lange syndrome (CdLS) is generally based on the presence of characteristic signs and symptoms during a thorough medical evaluation. In some cases, genetic testing can be ordered to confirm the diagnosis; however, it may not be informative in all people affected by CdLS as the underlying genetic cause is unknown in approximately 30% of cases. GeneReviews' Web site offers more specific information about the treatment and management of CdLS. Please click on the link to access this resource. | |
What are the treatments for Cornelia de Lange syndrome ? | How might Cornelia de Lange syndrome be treated? Because Cornelia de Lange syndrome (CdLS) affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this condition varies based on the signs and symptoms present in each person. For example, many people affected by CdLS have poor growth after birth and may require supplemental formulas and/or gastrostomy tube placement to meet nutritional needs. Ongoing physical, occupational, and speech therapies are often recommended to optimize developmental potential. Surgery may be necessary to treat skeletal abnormalities, gastrointestinal problems, congenital heart defects and other health problems. Medications may be prescribed to prevent or control seizures. The CdLS foundation's Web site offers more specific information about the treatment and management of CdLS. Please click on the link to access this resource. | |
What is (are) Annular atrophic lichen planus ? | Annular atrophic lichen planus (LP) is a rare form of lichen planus, which is a condition that affects the skin and/or mouth. In annular atrophic LP, specifically, affected people develop skin lesions with features of both annular LP and atrophic LP - ring-shaped, slightly raised, purple lesions with central atrophy (tissue breakdown). Although these lesions can be found anywhere on the body, they most commonly affect the trunk and legs. The exact underlying cause of annular atrophic LP is unknown. Treatment is not always necessary as some cases of annular atrophic LP resolve on their own. Mild cases that are diagnosed early can often be managed with topical steroids, while more intensive therapies may be required for severe cases. | |

What is (are) Anaplastic astrocytoma ? | Anaplastic astrocytoma is a rare, cancerous (malignant) type of brain tumor that arises from star-shaped brain cells called astrocytes. These cells surround and protect nerve cells in the brain and spinal cord. An anaplastic astrocytoma usually develops slowly over time, but may develop rapidly. Signs and symptoms vary depending on the location and size of the tumor and may include headaches, drowsiness, vomiting, and changes in personality or mental status. Some affected people have seizures, vision problems, weakness of the limbs, and/or coordination problems. Anaplastic astroctyomas usually occur sporadically but can be associated with a few rare, genetic disorders. Treatment may include surgery, radiation, and/or chemotherapy. | |
Is Anaplastic astrocytoma inherited ? | Are anaplastic astrocytomas inherited? Anaplastic astrocytomas are usually not inherited. These tumors typically occur sporadically, in people with no family history of astrocytomas. In most cases, the exact cause is unknown. Familial cases of isolated astrocytomas have been reported but are very rare. Astrocytomas can have a genetic link when they are associated with a few rare, inherited disorders. These include neurofibromatosis type I, Li-Fraumeni syndrome, Turcot syndrome, and tuberous sclerosis. Astrosytomas occur more frequently in people with one of these disorders. Like many other cancers, it is believed that isolated astrocytomas may occur due to a combination of genetic and environmental factors. This means that a person may carry a gene (or a combination of genes) that predisposes them to developing an astrocytoma, but it may not develop unless it is "triggered" by an environmental factor. | |
How to diagnose Anaplastic astrocytoma ? | Is genetic testing available for anaplastic astrocytomas? When anaplastic astrocytomas are not associated with an inherited condition, the cause typically remains unknown. In these cases, genetic testing is not available. However, genetic testing is available for the few genetic disorders that are associated with an increased risk for developing an astrocytoma. These include neurofibromatosis type I, Li-Fraumeni syndrome, Turcot syndrome, and tuberous sclerosis. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for these conditions. On the GTR Web site, search for a disorder to find out about the genetic tests that are available. The intended audience for the GTR is health care providers and researchers. Therefore, patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. | |
What is (are) Congenital anosmia ? | Congenital anosmia is a very rare condition in which people are born with a lifelong inability to smell. It may occur as an isolated abnormality (no additional symptoms) or be associated with a specific genetic disorder (such as Kallmann syndrome and congenital insensitivity to pain). Scientists suspect that isolated congenital anosmia occurs due to abnormal development of the olfactory system (the sensory system used for sense of smell) prior to birth. This may include abnormalities of the nasal cavity, disruptions in the pathway that carries information from the nose to the brain, and/or malformations of the portion of the brain that processes sense of smell. Unfortunately, there is currently no known cure or treatment for congenital anosmia. | |
What are the symptoms of Congenital anosmia ? | What are the signs and symptoms of Congenital anosmia? The Human Phenotype Ontology provides the following list of signs and symptoms for Congenital anosmia.

Signs and Symptoms Approximate number of patients (when available) Anosmia - Autosomal dominant inheritance - 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.

In these cases, the sign or symptom may be rare or common. | |
What causes Congenital anosmia ? | What causes congenital anosmia? Congenital anosmia may occur as an isolated abnormality or be associated with specific genetic disorders (such as Kallmann syndrome and congenital insensitivity to pain). Most cases of isolated congenital anosmia (not associated with additional symptoms) occur sporadically in people with no family history of the condition. In these people, the exact underlying cause of the condition is unknown. Most likely, there is more than one cause. Scientists suspect that the condition occurs due to abnormal development of the olfactory system (the sensory system used for sense of smell) prior to birth. This may include abnormalities of the nasal cavity, disruptions in the pathway that carries information from the nose to the brain, and/or malformations of the portion of the brain that processes sense of smell. Rarely, isolated congenital anosmia can affect more than one family member. This suggests that there may be a genetic component in some cases. One study found that some people affected by isolated congenital anosmia have changes (mutations) in PROKR2 or PROK2, two genes that have previously been reported in people with Kallmann syndrome (an inherited condition associated with congenital anosmia and other symptoms). To date, no other disease-causing genes have been identified. | |
Is Congenital anosmia inherited ? | Is congenital anosmia inherited? Most cases of isolated congenital anosmia (not associated with additional symptoms) occur sporadically in people with no family history of the condition. Rarely, more than one family member may be affected. In these families, the condition appears to be inherited in an autosomal dominant manner with reduced penetrance. Congenital anosmia can also by associated with specific genetic disorders such as Kallmann syndrome and congenital insensitivity to pain. In these cases, the inheritance varies based on the associated condition. For example, Kallmann syndrome can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive manner depending on the underlying genetic cause (it can be caused by mutations in several different genes). Congenital insensitivity to pain follows an autosomal recessive pattern of inheritance. | |
How to diagnose Congenital anosmia ? | How is congenital anosmia diagnosed? Isolated congenital anosmia (not associated with other symptoms) is a diagnosis of exclusion. This means that the diagnosis is made in people with suspicious signs and symptoms once other conditions that cause similar features have been ruled out. When an affected person has no recollection of ever being able to smell, the following tests may be ordered to support a diagnosis of congenital anosmia: A thorough physical examination and medical history to look for other conditions that may interfere with the sense of smell Smell tests, particularly those that determine the smallest amount of odor that someone can detect Brain Imaging (such as CT scan and MRI scan) as some people with congenital anosmia have malformations in the portion of the brian that processes smells Nasal endoscopy to look for abnormalities of the nasal cavity which may interfere with sense of smell Olfactory nerve testing to evaluate disruptions in the pathway that carries information from the nose to the brain | |

What is (are) Progressive bulbar palsy ? | Progressive bulbar palsy involves the brain stem. The brain stem is the part of the brain needed for swallowing, speaking, chewing, and other functions. Signs and symptoms of progressive bulbar palsy include difficulty swallowing, weak jaw and facial muscles, progressive loss of speech, and weakening of the tongue. Additional symptoms include less prominent weakness in the arms and legs, and outbursts of laughing or crying (called emotional lability). Progressive bulbar palsy is considered a variant form of amyotrophic lateral sclerosis (ALS). Many people with progressive bulbar palsy later develop ALS. While there is no cure for progressive bulbar palsy or for ALS, doctors can treat symptoms. | |
How to diagnose Progressive bulbar palsy ? | How is progressive bulbar palsy diagnosed? What tests aid in the diagnosis of progressive bulbar palsy? Progressive bulbar palsy is a difficult to diagnose condition. No one test or procedure offers a definitive diagnosis. Diagnosis is largely based upon the person's symptoms, tests that show how well their nerves are working (e.g., an EMG or electromyography), and ruling out other causes for the symptoms. Particularly, stroke and a condition called myasthenia gravis, may have certain symptoms that are similar to those of progressive bulbar palsy and must be ruled out prior to diagnosing this disorder. Testing for acetylcholine receptor-binding antibodies may be helpful in ruling out myasthenia gravis. Because of the lack of definitive tests, you may find it helpful to consult with a doctor who is experienced in diagnosing ALS. The ALS Association lists experts and specialty centers through their Web site at: http://www.alsa.org/community/als-clinics | |
What are the treatments for Progressive bulbar palsy ? | How is progressive bulbar palsy treated? Treatments aim to help people cope with the symptoms of progressive bulbar palsy, such as feeding tubes, devices to help with talking, and medicines to treat muscle spasms, weakness, drooling, sleep problems, pain, and depression. The Robert Packard Center for ALS Research at John Hopkins offers further general information on treatment: http://www.alscenter.org/living_with_als/treatment.html The Mayo Clinic provides information on treatment of ALS in general, which may be helpful: http://www.mayoclinic.org/diseases-conditions/amyotrophic-lateral-sclerosis/basics/treatment/con-20024397 If you are interested in learning about clinical trials, we recommend that you call the Patient Recruitment and Public Liaison (PRPL) Office at the National Institutes of Health (NIH) at 1-800-411-1222.

What causes Hepatocellular carcinoma, childhood ? | What causes hepatocellular carcinoma, childhood? A review of the literature suggests that knowledge regarding the cause of hepatocellular carcinoma in children is lacking due to the rarity of this disease. Children living in regions of the world where heptatitis B virus is common have been reported to have a much greater risk of developing this disease. Chronic infection by hepatitis C virus has also been linked to the development of hepatocellular carcinoma. Hepatocellular carcinoma has also been reported to develop in the presence of liver disease, cirrhosis, and inborn errors of metabolism. In addition, various other reported risk factors for developing hepatocellular carcinoma include: male sex, co-infection with other viral liver disease, co-infection with HIV, alcohol abuse, family history of this carcinoma, increased hepatic iron, increased serum alanine aminotransferase levels, exposure to aflatoxin B1 by food contamination, genetic variants of glutathione S-transferase, and various metabolic liver disorders. Chronic Epstein Barr virus infections have also been suggested to play a role in the development of hepatocellular carcinoma in Asian patients. This association remains to be confirmed in other populations. | |

What is (are) Pemphigus vulgaris ? | Pemphigus vulgaris is an autoimmune disorder that involves blistering of the skin and mucous membranes. It occurs almost exclusively in middle-aged or older people. Many cases begin with blisters in the mouth, followed by skin blisters that may come and go. In most cases, the exact cause of pemphigus vulgaris is unknown. It has rarely been observed in multiple members of the same family. Treatment is aimed at reducing symptoms and preventing complications. Severe cases are treated similarly to severe burns. | |
What causes Pemphigus vulgaris ? | What causes pemphigus vulgaris? Pemphigus vulgaris is an autoimmune disorder. The immune system produces antibodies against specific proteins in the skin and mucous membranes. These antibodies create a reaction that cause skin cells to separate. Although it is rare, some cases of pemphigus vulgaris are caused by certain medications. Medications that may cause this condition include: Blood pressure medications called ACE inhibitors Chelating agents such as penicillamine, which remove certain materials from the blood While in many cases the exact cause of pemphigus vulgaris remains unknown, several potentially relevant factors have been identified. Genetic factors: Predisposition to pemphigus is linked to genetic factors.Certain major histocompatibility complex (MHC) class II molecules, in particular alleles of human leukocyte antigen (HLA) DR4, appear to confer susceptibility to pemphigus vulgaris. Age: Peak age of onset is from 50-60 years. Infants with neonatal pemphigus typically recover after protection from their mother's antibodies have cleared their systems. The disease may, nonetheless, develop in children or in older persons, as well. Disease association: Pemphigus commonly occurs in individuals who also have other autoimmune diseases, particularly myasthenia gravis and thymoma. Pemphigus is not contagious. It does not spread from person to person. Though there can be a genetic predisposition to develop pemphigus, there is no indication the disease is hereditary. | |

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

What is (are) Opitz G/BBB syndrome ? | Opitz G/BBB syndrome is an inherited condition that affects several structures along the midline of the body. The most common features are wide-spaced eyes and defects of the larynx, trachea, and/or esophagus causing breathing problems and difficulty swallowing. Affected males usually have a urethra opening on the underside of the penis (hypospadias). Other features can include mild intellectual disability, cleft lip and/or a cleft palate, heart defects, an obstruction of the anal opening (imperforate anus), agenesis of the corpus callosum, and facial abnormalities. These features may vary, even among members of the same family. There are two forms of Opitz G/BBB syndrome, which are distinguished by their genetic causes and patterns of inheritance. The X-linked form is caused by mutations in the MID1 gene. Autosomal dominant Opitz G/BBB syndrome is caused by a deletion of 22q11.2, and is often referred to as 22q11.2 deletion syndrome. Treatment depends on the individuals specific needs. | |
What are the symptoms of Opitz G/BBB syndrome ? | What are the signs and symptoms of Opitz G/BBB syndrome? Opitz G/BBB syndrome mainly affects structures along the midline of the body. The most common features of the condition are wide-spaced eyes (hypertelorism); defects of the larynx, trachea, and/or esophagus causing breathing problems and difficulty swallowing (dysphagia); and in males, the urethra opening on the underside of the penis (hypospadias). Mild intellectual disability and developmental delay occur in about 50 percent of people with Opitz G/BBB syndrome. Delays in motor skills, speech delays, and learning difficulties may also occur. Some individuals with Opitz G/BBB syndrome have features similar to autistic spectrum disorders, including impaired communication and socialization skills. About half of affected individuals also have cleft lip with or without a cleft palate. Some have cleft palate alone. Heart defects, an obstruction of the anal opening (imperforate anus), and brain defects such as an absence of the tissue connecting the left and right halves of the brain (agenesis of the corpus callosum) occur in less than 50 percent of those affected. Facial abnormalities that may be seen in this disorder can include a flat nasal bridge, thin upper lip, and low set ears. These features vary among affected individuals, even within the same family. The signs and symptoms of the autosomal dominant form of the condition are comparable to those seen in the X-linked form. However, the X-linked form of Opitz G/BBB syndrome tends to include cleft lip with or without cleft palate, while cleft palate alone is more common in the autosomal dominant form. Females with X-linked Opitz G/BBB syndrome are usually mildly affected, as hypertelorism may be the only sign of the disorder. The Human Phenotype Ontology provides the following list of signs and symptoms for Opitz G/BBB syndrome.

What causes Opitz G/BBB syndrome ? | What causes Opitz G/BBB syndrome? The X-linked form of Opitz G/BBB syndrome is caused by mutations in the MID1 gene. The MID1 gene provides instructions for making a specific protein called midline-1. This protein helps regulate the function of microtubules, which are rigid, hollow fibers that make up the cell's structural framework (the cytoskeleton). Microtubules help cells maintain their shape, assist in the process of cell division, and are essential for the movement of cells (cell migration). The MID1 gene is a member of a group of genes called the TRIM (tripartite motif) family. The proteins produced from this large family of genes are involved in many cellular activities. Primarily, TRIM proteins play a role in the cell machinery that breaks down (degrades) unwanted proteins. As part of its protein degrading function, midline-1 is responsible for recycling certain proteins, including phosphatase 2A (PP2A), integrin alpha-4 (ITGA4), and serine/threonine-protein kinase 36 (STK36). The recycling of these three proteins so they can be reused instead of broken down is essential because they are needed for normal cellular functioning. Mutations in the MID1 gene lead to a decrease in midline-1 function, which prevents this protein recycling. As a result, certain proteins are not recycled, and they accumulate in cells. This buildup impairs microtubule function, resulting in problems with cell division and migration. Researchers speculate that the altered midline-1 protein affects how the cells divide and migrate along the midline of the body during development, resulting in the features of Opitz G/BBB syndrome. Some people who have a family history of X-linked Opitz G/BBB syndrome have no detectable MID1 mutation. The reason for this is not yet known, although some researchers have suggested the involvement of other unknown genes. The autosomal dominant form of Opitz G/BBB syndrome is caused by a deletion of a small piece of chromosome 22, specifically 22q11.2, which is why researchers consider this condition to be part of 22q11.2 deletion syndrome. It is not yet known which deleted gene(s) within this region of chromosome 22 specifically cause the signs and symptoms of Opitz G/BBB syndrome. In others with autosomal dominant Opitz G/BBB syndrome, the cause is related to a mutation in the SPECCIL gene.

Is Opitz G/BBB syndrome inherited ? | How is Opitz G/BBB syndrome inherited? Opitz G/BBB syndrome often has an X-linked pattern of inheritance. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes (the other sex chromosome is the Y chromosome). In most cases, males experience more severe symptoms of the disorder than females. This is because females have two different X chromosomes in each cell, and males have one X chromosome and one Y chromosome. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons, because fathers only pass a Y chromosome on to their sons (which is what makes them male). In some cases, an affected person inherits a MID1 mutation from an affected parent, while in other cases, it may result from a new mutation in the affected individual. These cases occur in people with no history of the disorder in their family. A female who has the X-linked form of Opitz G/BBB syndrome has a 25% (1 in 4) chance to have a daughter with the mutation, a 25% chance to have a son with the mutation, a 25% chance to have an unaffected daughter, and a 25% chance to have an unaffected son. This also means that there is a 50% chance, with each pregnancy, for the child to inherit the mutation. A male with the X-linked dominant form of Opitz G/BBB syndrome will pass the mutation on to all of his daughters and none of his sons. Researchers have also described an autosomal dominant form of Opitz G/BBB syndrome caused by a deletion in one copy of chromosome 22 in each cell. In some cases, an affected person inherits the chromosome with a deleted segment from a parent, while in other cases, the condition results from a new deletion in the affected individual. These cases occur in people with no history of the disorder in their family. Males and females with the autosomal dominant form of Opitz G/BBB syndrome usually have the same degree of severity of symptoms. A male or female who has the autosomal dominant form of Opitz G/BBB syndrome has a 50% (1 in 2) chance with each pregnancy for the child (male or female) to inherit the genetic abnormality. | |
How to diagnose Opitz G/BBB syndrome ? | How is Opitz G/BBB syndrome diagnosed? The diagnosis of Opitz G/BBB syndrome is usually based on clinical findings. In order to differentiate the X-linked form from 22q11.2 deletion syndrome (the autosomal dominant form), the pattern of inheritance within the family may be assessed. Molecular genetic testing for mutations in the MID1 gene is available for confirmation. Between 15 and 45% of males with clinically diagnosed Opitz G/BBB syndrome are found to have a mutation in this gene. | |
What are the treatments for Opitz G/BBB syndrome ? | How might Opitz G/BBB syndrome be treated? Because of the wide range of signs and symptoms that may be present in affected individuals, management of Opitz G/BBB syndrome typically incorporates a multidisciplinary team consisting of various specialists. Treatment for the condition may include surgery for significant abnormalities involving the larynx, trachea and/or esophagus; surgical intervention as needed for hypospadias, cleft lip and/or cleft palate, and imperforate anus; therapy for speech problems; surgical repair as needed for heart defects; neuropsychological support; and special education services. | |

What is (are) Diffuse gastric cancer ? | Diffuse gastric cancer or signet ring cell cancer is a type of cancer found most often in the glandular cells lining the stomach, but can also develop in the bowel, breast, pancreas, bladder, prostate or lung. The 2010 WHO (World Health Organization) classification recognizes four major histologic patterns of gastric cancers: tubular, papillary, mucinous and poorly cohesive (including signet ring cell carcinoma), plus uncommon histologic variants. The term "signet ring cell" is often used because the cells look like signet rings when viewed under a microscope. The signet cells are a type of epithelial cell. Epithelial tissue is skin tissue, covering and lining the body both inside and out. When diffuse gastric cancer is inherited it is called "hereditary diffuse gastric cancer." Treatment depends on the stage at which the cancer is found and may include chemotherapy, radiation therapy, or operations to remove the stomach (gastrectomy). | |
What are the symptoms of Diffuse gastric cancer ? | What are the signs and symptoms of Diffuse gastric cancer? Signs and symptoms of gastric cancer may include indigestion, stomach discomfort, bloating, mild nausea, loss of appetite, and heartburn.

What causes Diffuse gastric cancer ? | Can diffuse gastric cancer be caused by excessive drinking? Most of the time the exact cause of gastric cancer can not be determined; however there are many different factors that may put someone at an increased risk for developing stomach cancer. While it isn't clear if alcohol alone can increase this risk, it is thought that regular drinking may increase the risk in smokers. You can visit the following information pages develped by the National Cancer Insitute and Cancer Research UK to learn more about these risks. http://www.cancer.gov/cancertopics/wyntk/stomach/page4 http://www.cancerhelp.org.uk/help/default.asp?page=3903 | |
Is Diffuse gastric cancer inherited ? | Can diffuse gastric cancer be inherited? Diffuse gastric cancer can be inherited or can happen sporadically in a family. Sporadic means that the cancer occurred randomly for the first time in a individual and was not inherited from a parent. Hereditary diffuse gastric cancer (HDGC) is caused by mutations in the CDH1 gene. Individuals with a CDH1 mutation typically develop cancer before age 40. | |

What is (are) Lemierre syndrome ? | Lemierre syndrome is a rare and potentially life-threatening illness. The bacterium responsible for this disease is typically Fusobacterium necrophorum, although a wide variety of bacteria have been reported as causing the disease. The bacterial infection begins in the oropharynx then spreads through the lymphatic vessels. Following this primary infection, thrombophlebitis of the internal jugular vein (IJV) develops. The final phase of the disease occurs when septic emboli (pus-containing tissue) migrate from their original location in the body to various organs. The lungs are most commonly involved, however other sites may include the joints, muscle, skin and soft tissue, liver, and spleen. The symptoms of Lemierre syndrome include fever, sore throat, neck swelling, pulmonary involvement and joint pain. It is an uncommon disease that occurs in about one person per million per year. The disease primarily affects healthy young people before age 40. Diagnosis of Lemierre syndrome rests on the presence of a blood clot (or clots) in the IJV and blood cultures that show the presence of Fusobacterium necrophorum. Intravenous antibiotics are the mainstay of treatment. |
