train_0.png	What are the symptoms of Achalasia ?	Most people with achalasia experience difficulty swallowing, also known as dysphagia and heartburn. Other symptoms might include: regurgitation or vomiting, noncardiac chest pain, odynophagia (painful swallowing), and pain in the upper central region of the abdomen. Non esophageal symptoms might include: coughing or asthma, chronic aspiration (breathing a foreign object such as food into the airway), hoarseness or sore throat, and unintentional weight loss.

train_2.png	What are the symptoms of Carney triad ?	The Human Phenotype Ontology provides the following list of signs and symptoms for Carney triad. 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) Abdominal pain 90% Diarrhea 90% Gastrointestinal hemorrhage 90% Nausea and vomiting 90% Neoplasm of the lung 90% Neoplasm of the stomach 90% Neuroendocrine neoplasm 90% Sarcoma 90% Abnormality of the liver 50% Abnormality of the mediastinum 50% Ascites 50% Hypercortisolism 50% Anemia 7.5% Anorexia 7.5% Arrhythmia 7.5% Hypertension 7.5% Lymphadenopathy 7.5% Migraine 7.5% The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
train_3.png	What are the treatments for Blepharophimosis, ptosis, and epicanthus inversus syndrome type 1 ?	Management of blepharophimosis syndrome type 1 requires the input of several specialists including a clinical geneticist, pediatric ophthalmologist, eye plastic (oculoplastic) surgeon, endocrinologist, reproductive endocrinologist, and gynecologist. Eyelid surgery should be discussed with an oculoplastic surgeon to decide on the method and timing that is best suited for the patient. Traditionally, surgical correction of the blepharophimosis, epicanthus inversus, and telecanthus (canthoplasty) is performed at ages three to five years, followed about a year later by ptosis correction (usually requiring a brow suspension procedure). If the epicanthal folds are small, a "Y-V canthoplasty" is traditionally used; if the epicanthal folds are severe, a "double Z-plasty" is used. Unpublished reports have indicated that advanced understanding of the lower eyelid position has allowed for more targeted surgery that results in a more natural appearance. For a general explanation of these procedures and to locate an eye-care professional visit the Foundation of the American Academy of Ophthalmology and the National Eye Institute websites. To locate a surgeon through the American Society of Ophthalmic Plastic & Reconstructive Surgery click here. Generally, premature ovarian failure (POF) is treated with hormone replacement therapy. There is no specific treatment for POF caused by blepharophimosis syndrome type 1. Hormone replacement therapy is generally estrogen and progesterone and sometimes also includes testosterone. Birth control pills are sometimes substituted for hormone replacement therapy. Although health care providers can suggest treatments for some of the symptoms of POF, currently there is no scientifically established treatment to restore fertility for women diagnosed with POF. Women with POF are encouraged to speak to a health care professional. If you wish to obtain more information and support, you can visit the International Premature Ovarian Failure Association.

train_6.png	What is (are) Alopecia areata ?	Alopecia areata (AA) is an autoimmune disease in which the immune system mistakenly attacks the hair follicles. In most cases, hair falls out in small, round patches on the scalp. Although uncommon, hair loss can be more extensive in some people and affect other parts of the body. This condition can progress to complete loss of scalp hair (alopecia totalis) or total loss of all body hair (alopecia universalis). Although the exact cause of AA is unknown, roughly 20% of affected people have a family member with alopecia, suggesting that genetic factors may contribute to the development of the condition. There is no cure or approved therapy for AA; however, some people find that medications approved for other purposes can help regrow hair.
train_7.png	What is (are) Chronic active Epstein-Barr virus infection ?	Chronic active Epstein-Barr virus infection is a rare condition in which the body makes too many lymphocytes, a type of white blood cell. Lymphocytes are an important part of the immune system because they help fight off diseases and protect the body from infection. About 95% of adults are infected with Epstein-Barr virus (EBV). Most infections occur during childhood and do not cause any symptoms. EBV infection in adolescents or young adults can often result in infectious mononucleosis. Rarely, people infected with EBV develop a life-threatening condition called chronic active EBV virus (CAEBV). Patients with CAEBV most often have fever, liver dysfunction, an enlarged spleen (splenomegaly), swollen lymph nodes (lymphadenopathy), and low numbers of platelets (thrombocytopenia). Hematopoietic stem cell transplantation has shown promise in the treatment of CAEBV.
train_8.png	What causes Benign schwannoma ?	The cause of schwannomas is unknown. They sometimes occur in people with certain disorders including some types of neurofibromatosis (neurofibromatosis type 2 and schwannomatosis). In these cases, affected people have multiple tumors that are due to changes (mutations) in a gene. For example, neurofibromatosis type 2 is caused by mutations in the NF2 gene and schwannomatosis is caused by mutations in the SMARCB1 gene and the LZTR1 gene.

train_11.png	What are the treatments for Agenesis of the dorsal pancreas ?	Because agenesis of the dorsal pancreas is considered rare and few cases have been reported in the literature, there is limited information about how the condition as a whole might be treated or managed. However, there is current information about how some of the signs and symptoms associated with agenesis of the dorsal pancreas (such as pancreatitis) may be managed. For pancreatitis, individuals may be able to make themselves more comfortable during an attack, but they will most likely continue to have attacks until treatment is received for the underlying cause of the symptoms (when possible). If symptoms are mild, people might try the following preventive measures: stopping all alcohol consumption; adopting a liquid diet consisting of foods such as broth, gelatin, and soups (these simple foods may allow the inflammation process to get better); over-the-counter pain medications; and avoiding pain medications that can affect the liver (such as acetaminophen). Medical treatment is usually focused on relieving symptoms and preventing further aggravation to the pancreas. Certain complications of either acute pancreatitis or chronic pancreatitis may require surgery or a blood transfusion. In acute pancreatitis, the choice of treatment is based on the severity of the attack. Most people who are having an attack of acute pancreatitis are admitted to the hospital for oxygen (if having trouble breathing) and an intravenous (IV) line for medications and fluids. If needed, medications for pain and nausea may be prescribed. It may be recommended that no food or liquid is taken by mouth for a few days (this is called bowel rest). Some people may need a nasogastric (NG) tube to remove stomach juices which rests the intestine further, helping the pancreas recover. If the attack lasts longer than a few days, nutritional supplements may be administered through an IV line. In chronic pancreatitis, treatment focuses on relieving pain and avoiding further aggravation to the pancreas. Hyperglycemia (high blood sugar) management may depend on the exact cause if the condition in the affected individual. Management may include checking blood sugar levels with a blood glucose meter; checking urine for ketones; and adopting strategies to lower blood sugar level. Strategies might include exercise (only if urine ketones are not present); diet as discussed with a diabetes health educator or registered dietitian; and/or medication (especially if diet and exercise are not keeping blood sugar levels in the normal range) which may include insulin and/or other medications. Individuals seeking treatment options for themselves or others should speak with their health care provider about an individualized treatment plan; the information here is provided for general educational purposes only.
train_12.png	What is (are) Chronic hiccups ?	Chronic hiccups are unintentional movements (spasms) of the diaphragm followed by rapid closure of the vocal cords that persist for an extended period of time. Hiccups often develop for no apparent reason and typically go away on their own after a couple minutes. However, chronic hiccups last over two days and in rare cases, may continue for over a month. Hiccups that recur over long periods of time are also considered "chronic." Depending on how long the hiccups last, affected people may become exhausted, dehydrated and/or lose weight due to interruptions in sleep and normal eating patterns. Other complications may include irregular heart beat and gastroesophageal reflux. The exact underlying cause is often unknown; some cases may be caused by surgery, certain medications and/or a variety of health problems such as central nervous system (brain and spinal cord) abnormalities, psychological problems, conditions that irritate the diaphragm, and metabolic diseases. Treatment of chronic hiccups varies but may include medications and/or surgery.
train_13.png	What is (are) Chiari malformation type 2 ?	Chiari malformation type 2 (CM type II) is a type of Chiari malformation in which both the cerebellum and brain stem tissue extend into the foramen magnum (the hole at the skull base for passing of the spinal cord). This form is often accompanied by a type of spina bifida called myelomeningocele, and can also be accompanied by syringomyelia, hydrocephalus, or other abnormalities. Symptoms in infants may include stridor (wheezing sound); difficulty swallowing (dysphagia); feeding difficulties; hypotonia; and weak cry. Symptoms in children and/or adults may include headache; fatigue; loss of vision; tingling extremities; nausea; dysphagia; dizziness; muscle weakness; and ataxia. Adults and adolescents who previously had no symptoms may begin to have symptoms later in life. The exact cause of the condition is not known but it appears to be due to a developmental failure of the brain stem and upper spine. The term Arnold-Chiari malformation is technically specific to type II but may sometimes be used to describe other types of Chiari malformations.

train_16.png	What is (are) Calciphylaxis ?	Calciphylaxis is a disease in which blood vessels (veins and arteries) become blocked by a build-up of calcium in the walls of the vessels, preventing blood from flowing to the skin or internal organs. The lack of blood flow (ischemia) damages healthy tissue and causes it to die (necrosis). The most obvious and frequent symptom of calciphylaxis is damage to the skin, as ulcers can develop and become infected easily. Calciphylaxis can also affect fat tissue, internal organs, and skeletal muscle, causing infections, pain, and organ failure. These symptoms are often irreversible, and many individuals with calciphylaxis may not survive more than a few months after they are diagnosed due to infection that spreads throughout the body (sepsis), or organ failure. The exact cause of calciphylaxis is unknown. Treatments may include medications to reduce pain, antibiotics to treat infections, and various approaches to preventing the development or worsening of this condition.
train_17.png	What is (are) Androgen insensitivity syndrome ?	Androgen insensitivity syndrome is a condition that affects sexual development before birth and during puberty. People with this condition are genetically male, with one X chromosome and one Y chromosome in each cell. Because their bodies are unable to respond to certain male sex hormones (called androgens), they may have some physical traits of a woman. Androgen insensitivity syndrome is caused by mutations in the AR gene and is inherited in an X-linked recessive pattern.
train_18.png	What is (are) Chromosome 6q deletion ?	Chromosome 6q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 6. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 6q deletion include developmental delay, intellectual disability, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person.
train_19.png	What is (are) Castleman disease ?	Castleman disease (CD) is a rare condition that affects the lymph nodes and related tissues. There are two main forms: unicentric CD and multicentric CD. Unicentric CD is a "localized" condition that is generally confined to a single set of lymph nodes, while multicentric CD is a "systemic" disease that affects multiple sets of lymph nodes and other tissues throughout the body. The exact underlying cause of CD is currently unknown; however, it is thought to occur sporadically in people with no family history of the condition. Treatment varies based on the form of the condition, the severity of symptoms and whether or not the affected person also has an HIV and/or human herpes virus type 8 (HHV-8) infection. For more specific information about each form of CD, please visit GARD's unicentric Castleman disease and multicentric Castleman disease pages.
train_20.png	What are the treatments for Aplasia cutis congenita ?	The management of aplasia cutis congenita of the scalp is controversial.; both surgical and conservative treatment modalities have their proponents and opponents. The decision to use medical, surgical, or both forms of therapy in aplasia cutis congenita depends primarily on the size, depth, and location of the skin defect. Local therapy includes gentle cleansing and the application of bland ointment or silver sulfadiazine ointment to keep the area moist. Antibiotics may be utilized if overt signs of infection are noted. In many cases, other treatment is not necessary because the erosions and the ulcerations almost always heal on their own. Recently, a variety of specialized dressing materials have been developed and used. Surgical repair is not usually indicated if the defect is small. Recovery is generally uneventful, with gradual epithelialization and formation of a hairless, atrophic scar over several weeks. Small underlying bony defects usually close spontaneously during the first year of life. Surgical repair of large or multiple scalp defects may require excision with primary closure, if feasible, or the use of tissue expanders and rotation of a flap to fill the defect. On occasion, skin and bone grafts may also be required.
train_21.png	What are the symptoms of Celiac artery compression syndrome ?	Classically, individuals with celiac artery compression syndrome present with a triad of abdominal pain after eating, weight loss (usually >20 pounds), and abdominal bruit (abnormal sound of a blood vessel when blocked or narrowed). One review found that abdominal pain is the most common symptom, found to be present in approximately 80% of individuals, while weight loss was found in approximately 48% and abdominal bruit was appreciated in approximately 35%. Other symptoms include: nausea, diarrhea, vomiting, and delayed gastric emptying.
train_22.png	What are the symptoms of Coats disease ?	The signs and symptoms of Coats disease typically begin at an early age (between ages 6 and 8). Some people may only have a few or no symptoms, while others are very severely affected. The condition is almost always progressive (symptoms get worse over time), although alternating periods of sudden worsening with periods of no apparent progression are common. Early signs and symptoms may include loss of vision, crossed eyes (strabismus), and/or the development of a white mass in the pupil behind the lens of the eye (leukocoria). As the disease progresses, affected people may develop glaucoma; cataracts; reddish discoloration in the iris (rubeosis iridis or neovascular glaucoma); shrinking of the affected eyeball (phthisis bulbi); and/or swelling and irritation of the middle layer of the eye (uveitis). The majority of affected people eventually experience profound vision loss and retinal detachment. The Human Phenotype Ontology provides the following list of signs and symptoms for Coats disease. If the information is available, the table below includes how often the symptom is seen in people with this condition.

train_24.png	How to diagnose Chromosome 3p- syndrome ?	There are several different specialized tests that can be used to diagnose a chromosome 3p- syndrome. These include: Karyotype - a karyotype is a laboratory test that produces an image of a person's chromosomes. This test can be used to diagnose large deletions. FISH - a laboratory technique that is used to detect and locate a specific DNA sequence on a chromosome. During FISH, a chromosome is exposed to a small DNA sequence called a probe that has a fluorescent molecule attached to it. The probe sequence binds to its corresponding sequence on the chromosome. This test can be used in combination with karyotyping for deletions that are too small to be seen on karyotype, alone. However, FISH is only useful if the person ordering the test suspects there is a duplication of a specific region of 3p. Array CGH - a technology that detects deletions that are too small to be seen on karyotype.

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) Abdominal aortic aneurysm - 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.

Because this condition is rare, there are no established guidelines for treatment. Treatment is determined based on the severity of each affected individual's symptoms. Because birdshot chorioretinopathy is suspected to be an autoimmune disease, therapies aim to regulate the body's immune response. Therapies may include corticosteroids such as prednisone (by injection or medication taken by mouth) or medications that suppress the immune system such as cyclosporine.

train_39.png	Is Asperger syndrome inherited ?	Autism spectrum disorders including Asperger syndrome sometimes "run in families," but no specific inheritance pattern has been recognized. The condition is likely caused by a combination of genetic and environmental factors, which means that not all people with a genetic predisposition will be affected. A consultation with a genetics professional is recommended for those with specific questions about genetic risks to themselves or family members.
train_40.png	Is Abdominal aortic aneurysm inherited ?	Abdominal aortic aneurysm (AAA) is thought to be a multifactorial condition, meaning that one or more genes likely interact with environmental factors to cause the condition. In some cases, it may occur as part of an inherited syndrome. Having a family history of AAA increases the risk of developing the condition. A genetic predisposition has been suspected since the first report of three brothers who had a ruptured AAA, and additional families with multiple affected relatives have been reported. In some cases, it may be referred to as " familial abdominal aortic aneurysm." A Swedish survey reported that the relative risk of developing AAA for a first-degree relative of a person with AAA was approximately double that of a person with no family history of AAA. In another study, having a family history increased the risk of having an aneurysm 4.3-fold. The highest risk was among brothers older than age 60, in whom the prevalence was 18%. While specific variations in DNA (polymorphisms) are known or suspected to increase the risk for AAA, no one gene is known to cause isolated AAA. It can occur with some inherited disorders that are caused by mutations in a single gene, such as Marfan syndrome and Ehlers-Danlos syndrome, vascular type. However, these more typically involve the thoracoabdominal aorta. Because the inheritance of AAA is complex, it is not possible to predict whether a specific person will develop AAA. People interested in learning more about the genetics of AAA, and how their family history affects risks to specific family members, should speak with a genetics professional.
train_41.png	What is (are) Amelogenesis imperfecta ?	Amelogenesis imperfecta (AI) (amelogenesis - enamel formation; imperfecta - imperfect) is a disorder that affects the structure and appearance of the enamel of the teeth. This condition causes teeth to be unusually small, discolored, pitted or grooved, and prone to rapid wear and breakage. These dental problems, which vary among affected individuals, can affect both primary (baby) teeth and permanent teeth. There are 4 main types of AI that are classified based on the type of enamel defect. These 4 types are divided further into 14 subtypes, which are distinguished by their specific dental abnormalities and by their pattern of inheritance. AI can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive pattern.
train_42.png	What causes Bethlem myopathy ?	Bethlem myopathy is caused by mutations in the COL6A1, COL6A2, and COL6A3 genes. These genes each provide instructions for making one component of a protein called type VI collagen. This protein plays an important role in muscle, particularly skeletal muscle. Type VI collagen makes up part of the extracellular matrix, an intricate lattice that forms in the space between cells and provides structural support to the muscles. Mutations in the type VI collagen genes result in the formation of abnormal type VI collagen or reduced amounts of type VI collagen. This decrease in normal type VI collagen disrupts the extracellullar matrix surrounding muscle cells, leading to progressive muscle weakness and the other signs and symptoms of Bethlem myopathy.

train_47.png	What is (are) Acute alcohol sensitivity ?	Alcohol intolerance is characterized by immediate unpleasant reactions after drinking alcohol. The most common signs and symptoms of alcohol intolerance are stuffy nose and skin flushing. Alcohol intolerance is caused by a genetic condition in which the body is unable to break down alcohol efficiently, usually found in Asians. These individuals accumulate acetaldehyde, the primary metabolite of ethanol, because of a genetic polymorphism of aldehyde dehydrogenase (ALDH) that metabolizes acetaldehyde to nontoxic acetate.[9184] The only way to prevent alcohol intolerance reactions is to avoid alcohol. Alcohol intolerance isn't an allergy. However, in some cases, what seems to be alcohol intolerance may be a reaction to something in an alcoholic beverage, such as chemicals, grains or preservatives. Combining alcohol with certain medications also can cause reactions. In rare instances, an unpleasant reaction to alcohol can be a sign of a serious underlying health problem that requires diagnosis and treatment.
train_48.png	What are the symptoms of Acute intermittent porphyria ?	Some people who inherit the gene for AIP never develop symptoms and are said to have "latent" AIP. Those individuals that present with symptoms usually do so after puberty, probably because of hormonal influences, although other activating factors include: alcohol, drugs (e.g., barbiturates, steroids, sulfa-containing antibiotics), chemicals, smoking, reduced caloric intake, stress, and travel. Symptoms usually last several days, but attacks for which treatment is not received promptly may last weeks or months. Abdominal pain, which is associated with nausea and can be severe, is the most common symptom and usually the first sign of an attack. Other symptoms may include : Gastrointestinal issues (e.g., nausea, vomiting, constipation, diarrhea, abdominal distention, ileus) Urinary tract issues (e.g., urinary retention, urinary incontinence, or dysuria) Neurological issues (e.g., muscle weakness in the arms or legs, paralysis) Psychiatric issues (e.g., insomnia, hysteria, anxiety, apathy or depression, phobias, psychosis, agitation, delirium, somnolence, or coma) Individuals with AIP have an increased risk of developing hepatocellular carcinoma; some develop kidney failure.

In these cases, the sign or symptom may be rare or common.
train_50.png	What are the treatments for Acute febrile neutrophilic dermatosis ?	Left untreated, acute febrile neutrophilic dermatosis not associated with a more serious condition may disappear on its own within one to three months. Medications can improve skin lesions and associated symptoms in just two or three days, with the worst of the lesions disappearing within one to four weeks. Doctors usually prescribe systemic corticosteroids (prednisone or prednisolone) to treat this condition. These oral anti-inflammatory medications reduce redness, itching, swelling and allergic reactions. In the pediatric population, long-term use of corticosteroids can cause problems with linear growth, blood pressure, and blood glucose levels. Children may also have social sequelae associated with their use. Therefore, attempts are usually made to treat children with steroid-sparing drugs. Other treatment options include indomethacin, colchicine, potassium iodide, dapsone, cyclosporine, etretinate, pentoxifylline, clofazimine, doxycycline, metronidazole, isotretinoin, methotrexate, cyclophosphamide, chlorambucil, and interferon alpha, all of which have shown some success in the resolution of symtpoms. With or without treatment, the lesions rarely leave a mark or scar when they eventually disappear. Even after the lesions have resolved, treatment may continue, as recurrence of the condition is common. If an underlying cause can be identified, it should be treated (i.e. resection of solid tumors, treatment of infections, and discontinuation of causative medication). Successful therapy of the underlying disorder may promote resolution of acute febrile neutrophilic dermatosis and prevent recurrences.

train_57.png	What is (are) Chromosome 9 inversion ?	Chromosomes are the structures found in every cell of the body that contain our DNA, the instructions that tell our body what to do. Humans have 23 pairs of chromosomes, which means that each human cell contains 46 chromosomes. Each chromosome has a p and q arm; p is the short arm and q is the long arm. The p arm is always on the top and the q arm is on the bottom. Chromosome 9 inversion is when there are two breaks on chromosome 9. The segment between the breakpoints flips around and reinserts back into the same place on chromosome 9. If both breaks occur in the same arm of the chromosome, this is called a paracentric inversion. If one break occurs in the short arm and the other in the long arm of the chromosome, then this is called a pericentric inversion. Chromosome 9 inversions commonly occur as a pericentric inversion.
train_58.png	What is (are) Chronic fatigue syndrome ?	Chronic fatigue syndrome, also known as systemic exertion intolerance disease, is a condition that causes extreme, long-lasting fatigue which can limit the ability to participate in ordinary, daily activities. It generally occurs in young adults between the ages of 20 and 40 and is twice as common in women. The main symptom is disabling fatigue that does not improve with rest. Other signs and symptoms may include muscle pain; joint pain; concentration and memory problems; headaches; sleep problems; fever; sore throat; and/or tender lymph nodes. The cause of chronic fatigue syndrome is not known yet. Some researchers have proposed that this condition is caused by viral infections or by immunological, hormonal or mental or psychiatric problems, but none have been proved. It is also believed that there may be a genetic predisposition for this condition and stress-related events act as triggers. Because the symptoms are similar to many conditions that need to be ruled out, the diagnosis make take some time to be made and patients are frequently misunderstood. Those who are affected are typically highly functioning individuals who are "struck down" with this disease. There is still no cure for this condition but there are several clinical trials. Current treatment consists of cognitive and/or behavioral therapy and focuses on improving symptoms and may include medications to treat pain, sleep disorders and other associated problems. There is significant controversy and debate in the medical literature about the relationship between myalgic encephalomyelitis and chronic fatigue syndrome. Unfortunately there is no consensus on nomenclature or classification for these disorders, and different countries, organizations, and researchers continue to use different names to describe these conditions. Until a global consensus is reached on how to name and classify these disorders, confusion will persist.
train_59.png	What is (are) Abetalipoproteinemia ?	Abetalipoproteinemia is a condition characterized by the inability to fully absorb dietary fats, cholesterol and fat-soluble vitamins. Signs and symptoms appear in the first few months of life and can include failure to thrive; diarrhea; acanthocytosis; and stool abnormalities. Other features develop later in childhood and often impair the function of the nervous system, potentially causing slower intellectual development; poor muscle coordination; progressive ataxia; and an eye disorder called retinitis pigmentosa. Most of the symptoms are due to defects in the absorption and transport of vitamin E. Abetalipoproteinemia is caused by mutations in the MTTP gene and is inherited in an autosomal recessive manner. Early diagnosis, high-dose vitamin E therapy, and medium-chain fatty acid supplements may slow the progression of the nervous system abnormalities. Long-term outlook is reasonably good for most affected people who are diagnosed early. If left untreated, the condition can result in early death.

In many cases, significant damage has already occurred by the time treatment has started. Early diagnosis and treatment provide the best chance of recovery.
train_62.png	What is (are) Adenocarcinoma of the appendix ?	Cancer of the appendix is very rare and is typically found incidentally during appendectomies, in about 1% of the cases. According to a report published by the National Cancer Institute, using the Surveillance, Epidemiology, and End Results (SEER) database, appendix cancer account for about 0.4% of gastrointestinal tumors. There are several subytpes. The most common is the carcinoid type (66% of the total), with cyst-adenocarcinoma accounting for 20% and adenocarcinoma accounting for 10%. Then there are the rare forms of cancers which include adenocarcinoid, signet ring, non-Hodgkins lymphoma, ganglioneuroma, and pheochromocytoma. Benign primary tumors are mainly mucinous epithelial neoplasms, also called adenomas, cystadenoma, and benign neoplastic mucocele. Adenocarcinoma of the appendix is a epithelial cancer of the appendix. The term 'epithelium' refers to cells that line hollow organs and glands and those that make up the outer surface of the body. Epithelial cells help to protect or enclose organs. Some produce mucus or other secretions. Types of adenocarcinoma of the appendix include mucinous adenocarcinoma, non-mucinous adenocarcinoma, and signet cell carcinoma of appendix (which is the rarer involving only 4% of all the subtypes of appendix cancer).

Autoimmune autonomic ganglionopathy (AAG) is rare autoimmune disorder in which the body's immune system mistakenly attacks and damages certain parts of the autonomic nervous system. Signs and symptoms of the condition vary but may include severe orthostatic hypotension (low blood pressure upon standing); fainting; constipation; fixed and dilated pupils; urinary retention; and/or dry mouth and eyes. The exact underlying cause of AAG is poorly understood. Treatment depends on many factors including the severity of the condition and the signs and symptoms present in each person. Due to the rarity of AAG, there are no standard treatment protocols; however, treatment with plasmapheresis, intravenous (IV) immunoglobulin, corticosteroids or immunosuppressive drugs has been reported with variable success. Approximately one third of affected people may improve spontaneously without treatment, but the recovery is often incomplete.
train_65.png	What are the treatments for Chordoma ?	Unfortunately, because chordomas are quite rare, the best treatment for these tumors has yet to be determined. The current treatment for chordoma of the clivus often begins with surgery (resection) to remove as much of the tumor as possible. The extent of surgery, or the amount of tumor that may be removed, depends on the location of the tumor and how close it is to critical structures in the brain. Surgery is followed by radiation therapy to destroy any cancer cells that may remain after surgery. Several studies have suggested that proton beam radiation or combined proton/photon radiation may be more effect than conventional photon radiation therapy for treating chordomas of the skull base because proton radiation may allow for a greater dose of radiation to be delivered to the tumor without damaging the surrounding normal tissues. Approximately 60-70% of individuals treated with combined surgery and radiation therapy remained tumor-free for at least five years.
train_66.png	Is Charcot-Marie-Tooth disease type 2F inherited ?	Charcot-Marie-Tooth disease type 2F is inherited in an autosomal dominant manner. This means that only one mutated copy of the gene in each cell is sufficient to cause the condition. Most affected individuals inherit the mutated gene from an affected parent, but in some cases the mutation occurs for the first time in the affected individual (de novo mutation). When an individual with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated gene and have the condition.

train_68.png	What are the treatments for Bronchiolitis obliterans organizing pneumonia ?	Most cases of BOOP respond well to treatment with corticosteroids. If the condition is caused by a particular drug, stopping the drug can also improve a patient's condition. Other medications reported in the medical literature to be beneficial for individuals on a case-by-case basis include: cyclophosphamide, erythromycin in the form of azithromycin, and Mycophenolate Mofetil (CellCept). More esearch is needed to determine the long-term safety and effectiveness of these potential treatment options for individuals with BOOP. In rare cases, lung transplantation may be necessary for individuals with BOOP who do not respond to standard treatment options.

The episodes usually begin with twitching and stiffness of the face, and often wake up the child. The clonic activity causes a tingling feeling on one side of the mouth involving the tongue, lips, gum and inner side of the cheek. The seizure may also involve the throat which may make speech unclear and difficult to understand. Occasionally, both sides of the body may be affected, which can lead to loss of consciousness causing stiffness and jerking movements of the arms and legs. The child may also be incontinent. After an episode, a child may be sleepy and doze for a few hours. The Human Phenotype Ontology provides the following list of signs and symptoms for Benign rolandic epilepsy (BRE).

train_71.png	What are the treatments for Adolescent idiopathic scoliosis ?	Treatment of adolescent idiopathic scoliosis may involve observation, bracing and/or surgery. Treatment recommendations are generally dependent upon the risk of curve progression. Curves progress most during the rapid growth period of the patient (adolescent or pre-adolescent growth spurt). The potential for growth is evaluated by taking into consideration the patient's age, the status of whether females have had their first menstrual period, and radiographic parameters (x-ray studies). Detailed information about these treatment options can be accessed through the Scoliosis Research Society.

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.

The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. Prenatal testing may also be available for pregnancies at increased risk if the mutations in the family have been identified.
train_76.png	What causes Alport syndrome ?	Alport syndrome may be caused by mutations in either the COL4A3, COL4A4, or COL4A5 genes. These genes each provide instructions for making one component of a protein called type IV collagen, which plays an important role in the glomeruli of the kidneys. Glomeruli are clusters of specialized blood vessels that remove water and waste products from the blood and create urine. Mutations in the genes mentioned above result in abnormalities of the type IV collagen in glomeruli, which prevents the kidneys from properly filtering the blood. As a result, blood and protein pass into the urine. Over time, the kidneys become scarred and many people with Alport syndrome develop kidney failure. Type IV collagen is also an important component of the organ of Corti, an inner ear structure that transforms sound waves into nerve impulses for the brain. Alterations in type IV collagen may result in abnormal inner ear function, which can lead to hearing loss. In addition, type IV collagen plays a role in the eye, where it helps maintain the shape of the lens and the normal color of the retina. Mutations found in Alport syndrome may affect the shape of the lenses and the color of the retina.

train_78.png	What causes Acute febrile neutrophilic dermatosis ?	In many cases, the cause of acute febrile neutrophilic dermatosis is unknown (idiopathic). But sometimes, it can be a sign of an immune system response to one of the following: An upper respiratory tract infection, such as a chest infection or strep throat Blood disorders, especially acute myelogenous leukemia, a cancer of the blood and bone marrow Inflammatory bowel disease, such as ulcerative colitis or Crohn's disease Bowel or breast cancer Pregnancy Rheumatoid arthritis An injury at the site where the rash appears, such as an insect bite or needle prick Certain medications, including nonsteroidal anti-inflammatory drugs (NSAIDs)
train_79.png	What are the symptoms of Charcot-Marie-Tooth disease type 1A ?	CMT1 is generally slowly progressive over many years. However, affected individuals often experience long periods without any obvious deterioration or progression. Occasionally, individuals show accelerated deterioration of function over a few years. Nerve conduction velocities (NCVs) tend to slow progressively over the first two to six years of life, but they appear to remain relatively stable throughout adulthood. Worsening of signs and symptoms tends to be slow in the second to fourth decades of life. It remains to be confirmed whether, and to what extent, there is clinical and electrophysiological disease progression in affected adults; two studies of adult with CMT1A have shown conflicting results. Authors of one study reported disease progression over time (23 years on average), while authors of another study found that both patients and controls (individuals without the condition) had a similar decline of strength and of electrophysiological findings. The findings in the latter study suggested that the decline in adulthood in affected individuals may reflect a process of normal aging rather than on-going active disease. Any major changes in the pace of progression may warrant consideration of additional acquired, or possibly independently inherited forms, of neuromuscular diseases. The severity of signs and symptoms of CMT1A can vary greatly among affected individuals. Individuals who have questions about their own specific signs and symptoms and how they may relate to progression of CMT should speak with their health care provider. The Human Phenotype Ontology provides the following list of signs and symptoms for Charcot-Marie-Tooth disease type 1A.

train_81.png	What causes Charcot-Marie-Tooth disease type 2F ?	Charcot-Marie-Tooth disease type 2F (CMT2F) is caused by mutations in the HSPB1 gene. This gene provides instructions for making a protein (heat shock protein beta-1) which helps protect cells under adverse conditions. Heat shock proteins appear to be involved in activities such as cell movement, stabilizing the cell's framework, folding and stabilizing new proteins, repairing damaged proteins, and muscle contraction. Heat shock protein beta-1 is particularly abundant in nerve and muscle cells. In nerve cells, it helps to organize a network of threads that maintain the diameter of axons (neurofilaments), which are needed to transmit nerve impulses efficiently. It is unclear exactly how HSPB1 mutations lead to the axon abnormalities characteristic of CMT2F. Researchers suggest that mutations lead to an altered protein which clusters together and interferes with nerve cell function. Another possibility is that the altered protein disrupts the assembly of neurofilaments, which in turn may impair the transmission of nerve impulses.
train_82.png	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.
train_83.png	What is (are) Antisynthetase syndrome ?	Antisynthetase syndrome is a chronic autoimmune condition that affects the muscles and various other parts of the body. The signs and symptoms can vary but may include muscle inflammation (myositis), polyarthritis (inflammation of many joints), interstitial lung disease and Raynaud phenomenon. The exact underlying cause is unknown; however, the production of autoantibodies (antibodies that attack normal cells instead of disease-causing agents) that recognize and attack certain enzymes in the body called 'aminoacyl-tRNA synthetases' appears to be linked to the cause of the syndrome. Treatment is based on the signs and symptoms present in each person but may include corticosteroids, immunosuppressive medications, and/or physical therapy.

train_85.png	What are the treatments for Catamenial pneumothorax ?	Treatment of choice is with surgery, with video-assisted thoracoscopic surgery (VATS). Conventional thoracotomy may be occasionally necessary, particularly in repeat operations. It is very important to examine the large, thin tissue lining around the outside of the lungs and the inside of the chest cavity (pleura). Hormonal treatment with surgery prevents the repeat of catamenial and/or endometriosis-related pneumothorax. Gonadotrophin-releasing hormone (GnRH) for 6 to 12 months after the surgery is also often recommended.
train_86.png	What causes Autoimmune autonomic ganglionopathy ?	The cause of autoimmune autonomic ganglionopathy is not fully understood. An autoimmune component is presumed, as the body's own immune system damages a receptor in the autonomic ganglia (part of the peripheral autonomic nerve fiber). In one to two-thirds of affected individuals, this condition is associated with high titers of ganglionic acetylcholine receptor antibody (g-AchR antibody).. About 60% of cases follow an infection or other illness.
train_87.png	What are the symptoms of Bartter syndrome ?	The signs and symptoms associated with Bartter syndrome can vary depending on the form of Bartter syndrome an affected individual has. The antenatal forms (beginning before birth) can be life-threatening, while the classical form, beginning in early childhood, tends to be less severe. The antenatal forms of Bartter syndrome (types I, II and IV) may first be characterized by abnormally high levels of amniotic fluid surrounding the affected fetus (polyhydramnios); premature delivery; and possibly life-threatening salt (sodium-chloride) loss. Affected newborns may have fever, vomiting, diarrhea, failure to thrive, delayed growth, intellectual disability, and/or distinctive facial features (triangular face, prominent forehead, large eyes, protruding ears, and drooping mouth). Individuals with type IV may also have sensorineural deafness (hearing loss caused by abnormalities in the inner ear). Classical Bartter syndrome typically becomes apparent in infancy and is characterized by failure to thrive and constipation in the first year of life. Symptoms may include salt craving, fatigue, muscle weakness, growth delay and developmental delay. Loss of excess sodium chloride through the urine can lead to dehydration, constipation, and increased urine production (polyuria). Loss of excess calcium through the urine (hypercalciuria) can cause weakening of the bones (osteopenia). When this excess calcium becomes deposited in the kidneys, tissue in the kidneys can become hardened (nephrocalcinosis). Low levels of potassium in the blood (hypokalemia) cause the muscle weakness, cramping, and fatigue in affected individuals. The Human Phenotype Ontology provides the following list of signs and symptoms for Bartter syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition.

train_88.png	What is (are) Amyopathic dermatomyositis ?	Amyopathic dermatomyositis is a form of dermatomyositis characterized by the presence of typical skin findings without muscle weakness. Some of the skin changes that suggest dermatomyositis include a pink rash on the face, neck, forearms and upper chest; Gottron's papules and heliotrope eyelids. Pruritis and photosensitivity are common, as is scalp inflammation and thinning of the hair. While patients with amyopathic dermatomyositis should not have clinically evident muscle weakness, minor muscle abnormalities may be included. Fatigue is reported in at least 50% of patients. Some cases have been associated with internal malignancy and/or interstitial lung disease. Treatment may include sun avoidance, ample use of sunscreen, topical corticosteroids, antimalarial agents, methotrexate, mycophenolate mofetil, or intravenous (IV) immunoglobulin.
train_89.png	What is (are) Cicatricial pemphigoid ?	Cicatricial pemphigoid is a rare, chronic, blistering and scarring disease that affects the oral and ocular mucosa. Other mucosal sites that might be affected include the nasopharnyx, larynx, genitalia, rectum, and esophagus. The condition usually begins in late adulthood (e.g. 50's or 60's), affects more women than men, and has a variable prognosis. Scarring of the affected mucosa of the eye may lead to blindness and tends to be the most feared complication. A combination of environmental and genetic factors appear to play a role in the susceptibility of developing cicatricial pemphigoid. Although the specific causes of this condition have not been identified, it is considered an autoimmune disease that is characterized by the production of autoantibodies against basement membrane zone antigens such as BP180, BP230, and laminin 5. Treatment is dependent on the person's specific symptoms.

train_91.png	What are the symptoms of Charcot-Marie-Tooth disease type 2F ?	The subtypes of Charcot-Marie-Tooth type 2, including type 2F, have similar signs and symptoms. Affected individuals usually become symptomatic between the ages of 5 and 25, though onset can range from infancy to after the third decade of life. The most common first symptom is weakness of the feet and ankles, followed by slowly progressive weakness and atrophy of distal muscles in the feet and/or hands. Individuals often have decreased tendon reflexes and mild or no sensory loss. Adults with CMT2 often have bilateral foot drop, symmetric atrophy of muscles below the knee (stork leg appearance) and absent tendon reflexes in the legs. Mild sensory deficits of position, vibration, pain or temperature may occur in the feet, or sensation may be intact. Pain (especially in the feet) is reported by about 20%-40% of affected individuals. Other features that may be associated with CMT2 in a few individuals include hearing impairment; vocal cord or phrenic nerve involvement (which may result in difficulty with speech or breathing); restless legs; and sleep apnea. CMT2 is progressive over many years, but affected individuals often experience long periods without obvious progression. In some individuals, the condition may be so mild that it goes unrecognized. Affected individuals have a normal life span. The Human Phenotype Ontology provides the following list of signs and symptoms for Charcot-Marie-Tooth disease type 2F.

train_92.png	What is (are) Best vitelliform macular dystrophy ?	Best vitelliform macular dystrophy (BVMD) is a slowly progressive form of macular degeneration. It usually begins in childhood or adolescence, but age of onset and severity of vision loss can vary. Affected people first have normal vision, followed by decreased central visual acuity and distorted vision (metamorphopsia). Peripheral vision is not affected. BVMD is usually inherited in an autosomal dominant manner, but autosomal recessive inheritance has been reported. The condition is typically caused by mutations in the BEST1 gene; in a few cases the cause is unknown. Treatment is symptomatic and involves the use of low vision aids.
train_93.png	What is (are) Baylisascaris infection ?	Baylisascaris roundworms are intestinal parasites found in many different animals. Baylisascaris infection in humans is uncommon but can be severe. While Baylisascaris can infect different types of animals, Baylisascaris procyonis, carried by raccoons, is thought to pose the greatest risk to humans because raccoons often live in close proximity to humans. Humans can acquire the parasite by ingesting the eggs of infected raccoons. Young children are at greatest risk for Baylisascaris infection because they are more likely to put contaminated soil in their mouths. Though rare, human infections can be severe if the parasite invades the eye (ocular larva migrans), organs (visceral larva migrans), or the brain (neural larva migrans). Symptoms of a Baylisascaris infection may include nausea, fatigue, an enlarged liver, loss of coordination, lack of muscle control, blindness, and coma. Baylisascaris infections cannot be spread from one person to another. No drug has been found to be completely effective against Baylisascaris infections in humans though albendazole has been used in some cases.
train_94.png	What is (are) Autoimmune hemolytic anemia ?	Autoimmune hemolytic anemia (AIHA) occurs when your immune system makes antibodies that attack your red blood cells. This causes a drop in the number of red blood cells, leading to hemolytic anemia. Symptoms may include unusual weakness and fatigue with tachycardia and breathing difficulties, jaundice, dark urine and/or splenomegaly. AIHA can be primary (idiopathic) or result from an underlying disease or medication. The condition may develop gradually or occur suddenly. There are two main types of autoimmune hemolytic anemia: warm antibody hemolytic anemia and cold antibody hemolytic anemia. Treatment may include corticosteroids such as prednisone, splenectomy, immunosuppressive drugs and/or blood transfusions.

train_96.png	What are the treatments for Chronic inflammatory demyelinating polyneuropathy ?	The standard therapies for CIDP appear to be equally effective and include: intravenous immune globulin (IVIG) - adds large numbers of antibodies to the blood plasma to reduce the effect of the antibodies that are causing the problem glucocorticoids - help reduce inflammation and relieve symptoms plasma exchange - remove antibodies from the blood The treatment choice is influenced by the preference of the affected person, side effects, treatment cost, duration, ease of administration, and availability. Advantages and disadvantages of standard therapies may include the following: IVIG and plasma exchange may lead to a more rapid improvement in CIDP than glucocorticoid therapy, but are less likely than glucocorticoids to produce a remission IVIG is expensive, and its supply is sometimes limited Glucocorticoids are inexpensive, but chronic use is limited by common and important side effects Plasma exchange is expensive, invasive, and available only at specialized centers Other medications that suppress the immune system (immunosuppressants) may also be used. Physiotherapy may improve muscle strength, function and mobility.

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.
train_98.png	What causes Abetalipoproteinemia ?	Abetalipoproteinemia is caused by changes (mutations) in the MTTP gene. The MTTP gene gives the body instructions to make a protein needed for creating beta-lipoproteins. These lipoproteins are necessary for the body to absorb fats, cholesterol, and fat-soluble vitamins (vitamins A, D, E and K), and for transporting these substances in the blood. Mutations in the MTTP result in a lack of beta-lipoproteins, leading to an inability to absorb and transport these substances. This in turn leads to the nutritional and neurologic problems in affected people.
train_99.png	What is (are) AL amyloidosis ?	AL amyloidosisis the most common form of amyloidosis, a group of disorders in which an abnormal protein called amyloid builds up in tissues and organs. The signs and symptoms of AL amyloidosis vary among patients because the build up may occur in the tongue, intestines, muscles, joints, nerves, skin, ligaments, heart, liver, spleen, or kidneys. To diagnose AL amyloidosis, healthcare professionals use blood or urine tests to identify signs of amyloid protein and a biopsy to confirm the diagnosis. Treatment may include chemotherapy directed at the abnormal plasma cells, stem cell transplantation, or other treatments based on which symptoms have developed.
