Input: What causes Tumor necrosis factor receptor-associated periodic syndrome ?

Output: What causes tumor necrosis factor receptor-associated periodic syndrome (TRAPS)? TRAPS is a genetic condition caused by mutations in a gene called TNFRSF1A. This gene gives the body instructions to make a protein called tumor necrosis factor receptor 1 (TNFR1). This protein exists in cell membranes where it binds to another protein called tumor necrosis factor (TNF). The binding sends signals that tell the cells to trigger inflammation (producing immune system proteins) or self-destruct. Most TNFRSF1A gene mutations that cause TRAPS result in incorrectly-shaped TNFR1 proteins, which become trapped in cells and cannot reach the surface to bind with TNF. The trapped proteins then clump together and are thought to trigger other pathways involved in causing inflammation. Affected people typically have a mutation in only one of their 2 copies of the TNFRSF1A gene, so some normal TNFR1 proteins are still produced, leading to even more inflammation. This is what leads to excess inflammation in people with TRAPS. It is unclear if abnormalities in the cells' ability to self-destruct also plays a role in causing the features of TRAPS. </s>


Input: Is Tumor necrosis factor receptor-associated periodic syndrome inherited ?

Output: How is tumor necrosis factor receptor-associated periodic syndrome (TRAPS) inherited? TRAPS is inherited in an autosomal dominant manner. This means that having a mutation in only one of the 2 copies of the responsible gene is enough to cause signs and symptoms of the condition. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated copy of the gene. In many cases, a person with TRAPS inherits the condition from an affected parent. In other cases, the mutation occurs for the first time in the affected person and is not inherited from a parent. For unknown reasons, some people who inherit the mutated gene never develop features of TRAPS. When this occurs, a condition is said to have reduced penetrance. </s>


Input: What are the treatments for Tumor necrosis factor receptor-associated periodic syndrome ?

Output: How might tumor necrosis factor receptor-associated periodic syndrome (TRAPS) be treated? While there is no proven treatment for TRAPS, non steroidal anti-inflammatory drugs (NSAIDS) may be used to relieve symptoms of fever, and corticosteroids may be used to reduce severity of symptoms in most people. However, these medications typically don't decrease the frequency of attacks. Etanercept, a TNF inhibitor, has been shown to be effective but its efficacy tends to wane over time. Standard doses of etanercept twice a week have been shown to decrease the frequency, duration, and severity of attacks in some people and it may also reverse or slow the progression of amyloidosis. More studies are needed to evaluate this medication for TRAPS. Additional information about the treatment of TRAPS can be viewed on Medscape's Web site. </s>


Input: What is (are) Human T-cell leukemia virus type 2 ?

Output: Human T-cell leukemia virus, type 2 (HTLV-2) is a retroviral infection that affect the T cells (a type of white blood cell). Although this virus generally causes no signs or symptoms, scientists suspect that some affected people may later develop neurological problems and/or chronic lung infections. HTLV-2 is spread by blood transfusions, sexual contact and sharing needles. It can also be spread from mother to child during birth or breast-feeding. There is no cure or treatment for HTLV-2 and it is considered a lifelong condition; however, most infected people remain asymptomatic (show no symptoms) throughout life. </s>

Input: What is (are) Pseudohypoparathyroidism type 1C ?

Output: Pseudohypoparathyroidism type 1C is a genetic disorder that is very similar to hypoparathyroidism (parathyroid hormone levels are too low). However, pseudohypoparathyroidism is caused by no response to parathyroid hormone rather than having too little of the hormone itself. This causes low calcium and high phosphate levels in the blood. This condition is also associated with  a group of symptoms referred to as Albright's hereditary osteodystrophy, which includes short stature, a round face, obesity, and short hand bones. This disorder is different than pseudohypoparathyroidism type 1A because people with type 1C do not have abnormal activity of a particular protein (stimulatory protein G (Gs alpha)). Type 1C is inherited in an autosomal dominant fashion and is caused by a specific spelling mistake (mutation) in the GNAS gene. </s>

Input: What is (are) Isovaleric acidemia ?

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


Input: What are the symptoms of Isovaleric acidemia ?

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

Input: What causes Isovaleric acidemia ?

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


Input: Is Isovaleric acidemia inherited ?

Output: How is isovaleric acidemia inherited? Isovaleric acidemia is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. </s>


Input: What are the treatments for Isovaleric acidemia ?

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


Input: What is (are) Malignant peripheral nerve sheath tumor ?

Output: A malignant peripheral nerve sheath tumor (MPNST) is a tumor that develops from nerve tissue.  The first symptom of MPNST is a lump or mass that increases in size, sometimes causing pain or a tingling sensation.  MPNST is considered an aggressive tumor because there is up to a 65% chance of the tumor regrowing after surgery (a recurrence), and approximately 40% chance of spreading to distant parts of the body (a metastasis), most commonly to the lung.  Treatment of MPNST begins with surgery to remove as much of the tumor as possible.  Radiation therapy may be used to decrease the chance of a recurrence.  Chemotherapy might be used if the whole tumor cannot be removed during surgery, or to treat a metastasis.  MPNSTs are quite rare, occurring in 0.001% of the general population.  Approximately 25-50% of MPNSTs are associated with a genetic condition known as neurofibromatosis type 1. </s>


Input: What is (are) BRCA1 hereditary breast and ovarian cancer syndrome ?

Output: BRCA1 hereditary breast and ovarian cancer syndrome (BRCA1 HBOC) is an inherited condition that is characterized by an increased risk for a variety of different cancers.

Input: What causes Mandibulofacial dysostosis with microcephaly ?

Output: What causes mandibulofacial dysostosis with microcephaly? Mandibulofacial dysostosis with microcephaly (MFDM) is caused by mutations in the EFTUD2 gene. This gene gives the body instructions for making part of spliceosomes, which help process a type of RNA- a chemical cousin of DNA that serves as a genetic blueprint for making proteins. Mutations in EFTUD2 impair the production or function of the enzyme from the gene, which impairs the processing of mRNA. However, at this time, it is not clear how this process causes the specific symptoms of MFDM. </s>


Input: Is Mandibulofacial dysostosis with microcephaly inherited ?

Output: How is mandibulofacial dysostosis with microcephaly inherited? Mandibulofacial dysostosis with microcephaly (MFDM) is inherited in an autosomal dominant manner. This means that having one mutated copy of the responsible gene in each cell of the body is enough to cause signs and symptoms of the condition. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated copy of the gene. Most cases of MFDM are due to new mutations that occur for the first time in the affected person (called de novo mutations), and are not inherited from a parent. In other cases, an affected person inherits the mutation from a parent. The parent may be mildly affected or may be unaffected. Sometimes, an unaffected parent has the mutation only in some or all of their sperm or egg cells (not their body cells), which is known as germline mosaicism. </s>

Genetic testing is available for mandibulofacial dysostosis with microcephaly (MFDM) and confirms the diagnosis in virtually all people suspected of having MFDM. There are two approaches to genetic testing for this condition. One is sequence analysis of the EFTUD2 gene to identify a mutation (which detects ~91% of affected people), and the other is deletion analysis (which detects ~9%), for people in whom sequencing does not detect a mutation. When a diagnosis of MFDM is strongly suspected but genetic testing is inconclusive, a clinical diagnosis may still be appropriate. However, given the high sensitivity of genetic testing for this condition, other disorders with overlapping features should first be carefully considered. The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. </s>


Input: What are the treatments for Mandibulofacial dysostosis with microcephaly ?

Output: How might mandibulofacial dysostosis with microcephaly be treated? Individualized treatment of craniofacial features is managed by a multidisciplinary team which may include various specialists. Surgery may be needed for a variety of abnormalities, in the newborn period or beyond. Treatment of hearing loss is individualized, and may involve conventional hearing aids, bone-anchored hearing aid, and/or cochlear implants. Occupational, physical, and/or speech/language therapies are involved as needed to optimize developmental outcome. Additional treatment information is available on GeneReviews' Web site. </s>


Input: What is (are) Rett syndrome ?

Output: Rett syndrome is a progressive, neuro-developmental condition that primarily affects girls. Affected girls appear to have normal psychomotor development during the first 6 to 18 months of life, followed by a developmental "plateau," and then rapid regression in language and motor skills. Additional signs and symptoms may include repetitive, stereotypic hand movements; fits of screaming and inconsolable crying; autistic features; panic-like attacks; teeth grinding (bruxism); episodic apnea and/or hyperpnea; gait ataxia and apraxia; tremors; seizures; and slowed head growth. Some people have an atypical form of Rett syndrome that may be more mild or more severe. Classic Rett syndrome is most commonly caused by mutations in the MECP2 gene and is usually inherited in an X-linked dominant manner. The vast majority of cases are not inherited from a parent, but are due to a new mutation in the affected person. Treatment mainly focuses on the specific signs and symptoms of the condition. </s>

Input: What causes Rett syndrome ?

Output: What causes Rett syndrome? Rett syndrome is typically caused by changes (mutations) in the MECP2 gene. This gene provides instructions for making a protein (MeCP2) needed for the development of the nervous system and normal brain function. Mutations in the MECP2 gene that cause Rett syndrome can change the MeCP2 protein or result in the production of too little protein, which appears to disrupt the normal function of neurons and other cells in the brain. Several conditions caused by changes in other genes (such as FOXG1 syndrome) have overlapping signs and/or symptoms of Rett syndrome. These conditions were once thought to be variant forms of Rett syndrome, but are now usually considered to be separate disorders. </s>


Input: Is Rett syndrome inherited ?

Output: Is Rett syndrome inherited? Although Rett syndrome is a genetic disorder, less than 1 percent of recorded cases are inherited or passed from one generation to the next. Most cases are sporadic, which means the mutation occurs randomly, and are not inherited. A few families have been described with more than one affected family member. These cases helped researchers determine that Rett syndrome has an X-linked dominant 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 inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the condition. </s>


Input: What is (are) Peters plus syndrome ?

Output: Peters plus syndrome is a genetic condition characterized by abnormalities of the front part of the eye called the anterior chamber, short stature, cleft lip with or without cleft palate, and distinctive facial features.  The most common eye abnormality is Peters anomaly which involves the thinning and clouding of the cornea and attachment of the iris to the cornea causing blurred vision. Other eye abnormalities such as glaucoma and cataracts are common. The severity of symptoms may vary from person to person. The only gene that has been associated with Peters plus syndrome is B3GALTL. The syndrome is inherited in an autosomal recessive fashion. Treatment varies based on the severity of the symptoms; however, regular appointments with an ophthalmologist and avoidance of agents that increase the risk of glaucoma (e.g., corticosteroids) is recommended. </s>

Input: What causes Chromosome 4q deletion ?

Output: What causes chromosome 4q deletion? People with chromosome 4q deletion are missing genetic material located on the long arm (q) of chromosome 4 in each cell. Scientists suspect that many of the features seen in people affected by this condition are caused by the deletion and/or disruption of certain genes found on 4q. The severity of the condition and the associated signs and symptoms vary depending on the size and location of the deletion and which genes are involved. For example, deletion of the following genes may contribute to the features seen in some affected people: BMP3 - skeletal abnormalities and short stature SEC31A - distinctive craniofacial features PKD2 - kidney abnormalities GRID2, NEUROG2 - neurological problems such as seizures, hypotonia, and delayed motor development (i.e. sitting up, walking, etc) ANK2, HAND2 - heart defects and/or arrhythmias FGF2 - limb (arms and legs) abnormalities Researchers are working to learn more about the other genes on 4q that may contribute to the features seen in people with a chromosome 4q deletion. </s>


Input: Is Chromosome 4q deletion inherited ?

Output: How is chromosome 4q deletion inherited? Chromosome 4q deletion is usually not inherited. The deletion often occurs sporadically as a random event during the formation of the egg or sperm. In this case, a person would have no family history of the condition but could pass the deletion on to children. Rarely, this deletion is passed down from parent to child. However, the symptoms and severity can vary between family members. </s>


Input: How to diagnose Chromosome 4q deletion ?

Output: How is chromosome 4q deletion diagnosed? There are several different specialized tests that can be used to diagnose a chromosome 4q deletion. 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 deletion of a specific region of 4q. Array CGH - a technology that detects deletions that are too small to be seen on karyotype. </s>


Input: What are the treatments for Chromosome 4q deletion ?

Output: How might chromosome 4q deletion be treated? Because chromosome 4q deletion affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this deletion varies based on the signs and symptoms present in each person. For example, babies with congenital heart defects and certain skeletal abnormalities may require surgery. Children with bone or muscle problems and/or delayed motor milestones (i.e. walking) may be referred for physical or occupational therapy. Certain medications may be prescribed to treat seizures. Special education services are often necessary for children with intellectual disability.

Input: What is (are) Primary lateral sclerosis ?

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


Input: What are the symptoms of Primary lateral sclerosis ?

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

Input: How to diagnose Primary lateral sclerosis ?

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

Input: What is (are) Sertoli cell-only syndrome ?

Output: Sertoli cell-only syndrome (SCO syndrome) is a condition of the testes that causes infertility in males due to having only Sertoli cells (cells that nurture immature sperm) lining the seminiferous tubules (tubes inside the testicles where sperm develop). Men typically learn they are affected between ages 20-40 when being evaluated for infertility and are found to have no sperm production (azoospermia). The diagnosis is made based on testicular biopsy findings. Other signs and symptoms are rare, but are secondary to the underlying condition causing SCO syndrome. Most cases are idiopathic (of unknown cause), but causes may include deletions in the azoospermia factor (AZF) region of the Y chromosome, or Y-chromosome microdeletions (referred to as Y chromosome infertility); Klinefelter syndrome; exposure to chemicals and toxins; history of radiation therapy; and history of severe trauma. There is not currently a known effective treatment for the condition.

Input: What causes MYH7-related scapuloperoneal myopathy ?

Output: What causes MYH7-related scapuloperoneal myopathy? MYH7-related scapuloperoneal myopathy is caused by mutations in the MYH7 gene. This gene, located on chromosome 14q12, provides instructions for making a protein known as the cardiac beta ()-myosin heavy chain. This protein is found in heart (cardiac) muscle and in type I skeletal muscle fibers. Type I fibers, which are also known as slow-twitch fibers, are one of two types of fibers that make up skeletal muscles.

Input: What is (are) Neurofibromatosis type 1 ?

Output: Neurofibromatosis type 1 (NF1) is a rare, inherited condition that is characterized primarily by changes in skin coloring and the development of multiple benign tumors along the nerves of the skin, brain, and other parts of the body. The severity of the condition and the associated signs and symptoms vary significantly from person to person. NF1 is caused by changes (mutations) in the NF1 gene and is inherited in an autosomal dominant manner. In approximately 50% of cases, the condition is inherited from an affected parent. Other cases may result from new (de novo) mutations in the gene which occur in people with no history of the condition in their family. Treatment is based on the signs and symptoms present in each person. </s>


Input: What are the symptoms of Neurofibromatosis type 1 ?

Output: What are the signs and symptoms of Neurofibromatosis type 1? People affected by neurofibromatosis type 1 (NF1) have an increased risk of developing many different types of tumors (both cancerous and noncancerous). Almost all people with NF1 have neurofibromas, which are benign tumors that can affect nearly any nerve in the body. Most will develop these tumors on or just underneath the skin; however, neurofibromas can also grow in other places in the body and may even affect multiple nerves. Malignant peripheral nerve sheath tumors, which also grow along the nerves throughout the body, are the most common cancerous tumor found in people with NF1 and occur in approximately 10% of affected people. In children with NF1, the most common tumors are optic glioma (tumors that grow along the nerve leading from the eye to the brain) and brain tumors. Optic gliomas associated with NF1 are often asymptomatic although they can lead to vision loss. Other features of NF1 may include: Caf au lait spots (flat patches on the skin that are darker than the surrounding area) Freckling, especially in the underarm and groin Lisch nodules (clumps of pigment in the colored part of the eye that do not interfere with vision) Learning disabilities Seizures Autism spectrum disorder High blood pressure Short stature An unusually large head (macrocephaly) Skeletal abnormalities such as scoliosis GeneReview's Web site offers more specific information about the features of NF1.

Input: What causes Neurofibromatosis type 1 ?

Output: What causes neurofibromatosis type 1? Neurofibromatosis type 1 is caused by changes (mutations) in the NF1 gene. NF1 is a tumor suppressor gene, which means that it encodes a protein that stops cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in NF1 result in an abnormal protein that is unable to carry out its normal role. This contributes to the development of the many different types of tumors found in neurofibromatosis type 1. People with neurofibromatosis type 1 are typically born with one mutated copy of the NF1 gene in each cell and are, therefore, genetically predisposed to develop the tumors associated with the condition. For a tumor to form, two copies of the NF1 gene must be altered. The mutation in the second copy of the NF1 gene is considered a somatic mutation because it occurs during a person's lifetime and is not inherited. Almost everyone who is born with one NF1 mutation acquires a second mutation in many cells and develops the tumors characteristic of neurofibromatosis type 1. </s>


Input: Is Neurofibromatosis type 1 inherited ?

Output: How is neurofibromatosis type 1 inherited? Neurofibromatosis type 1 (NF1) is inherited in an autosomal dominant manner. This means that a person only needs a change (mutation) in one copy of the responsible gene in each cell to have a genetic predisposition to the tumors associated with NF1. In approximately half of cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene; these cases occur in people with no history of the disorder in their family. A person with NF1 has a 50% chance with each pregnancy of passing along the altered gene to his or her child. </s>


Input: How to diagnose Neurofibromatosis type 1 ?

Output: Is genetic testing available for neurofibromatosis type 1? Although it is usually not necessary for diagnosis, genetic testing is available for NF1, the gene known to cause neurofibromatosis type 1. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is neurofibromatosis type 1 diagnosed? The diagnosis of neurofibromatosis type 1 (NF1) is usually based on the presence of characteristic signs and symptoms. Specifically, doctors look for two or more of the following features to make a diagnosis of NF1: Six or more cafe-au-lait spots (measuring more than 5 mm across in children and more than 15 mm across in adolescents and adults) Two or more neurofibromas of any type or one plexiform neurofibroma (a neurofibroma that involves many nerves) Freckling in the underarm and/or groin Optic glioma Two or more Lisch nodules (clumps of pigment in the colored part of the eye that do not interfere with vision) Bone abnormalities including sphenoid dysplasia (absence of bone surrounding the eye) or tibial pseudarthrosis (incomplete healing of a fracture) A parent, sibling, or child who has been diagnosed with NF1 Because many of the features associated with NF1 develop with age, it can sometimes take several years to make a diagnosis in children without a family history of the condition. Genetic testing for changes (mutations) in the NF1 gene is available, but it is often not necessary. Prenatal testing and preimplantation genetic diagnosis is only an option if the disease-causing mutation in the family is known. </s>


Input: What are the treatments for Neurofibromatosis type 1 ?

Output: How might neurofibromatosis type 1 be treated? The treatment of neurofibromatosis type 1 (NF1) is based on the signs and symptoms present in each person. There is currently no way to prevent or stop the growth of the tumors associated with NF1. Neurofibromas located on or just below the skin that are disfiguring or irritating may be surgically removed. Malignant peripheral nerve sheath tumors are generally treated with complete surgical excision (when possible) although some cases may require the addition of chemotherapy and/or radiation therapy. Most optic gliomas associated with NF1 do not cause any symptoms and therefore, do not require treatment; however, optic gliomas that threaten vision may be treated with surgery and/or chemotherapy. Surgery may also be recommended to correct some of the bone malformations (such as scoliosis) associated with NF1.

Input: What causes Glycogen storage disease type 13 ?

Output: What causes glycogen storage disease type 13? Glycogen storage disease type 13 (GSD13) is caused by changes (mutations) in the ENO3 gene.  Glycogen is a substance that is stored in muscle tissue and is used as an important source of energy for the muscles during movement and exercise.  The ENO3 gene makes a chemical called enolase, which is an enzyme that helps the muscles use glycogen for energy.  In GSD13, the ENO3 genes do not work properly such that the body cannot make enolase, and as a result, the muscles do not have enough energy to work properly. </s>


Input: How to diagnose Glycogen storage disease type 13 ?

Output: How is glycogen storage disease type 13 diagnosed? Glycogen storage disease type 13 is diagnosed by taking a sample of muscle tissue (muscle biopsy) to determine if there is enough of the chemical enolase working in the muscle cells.  Genetic testing can also be done to look for changes (mutations) in the ENO3 gene. </s>

Input: What is (are) Inflammatory myofibroblastic tumor ?

Output: An inflammatory myofibroblastic tumor (IMT) is an uncommon, presumably benign (non-cancerous) tumor made up of cells called myofibroblastic spindle cells. It usually develops in children or young adults, but can affect people of any age. An IMT can occur in almost any part of the body but is most commonly found in the lung, orbit (eye socket), peritoneum (lining of the abdominal cavity and internal organs), and mesentery. Signs and symptoms vary depending on the site of the tumor. Some people with an IMT are asymptomatic, while others may have nonspecific respiratory symptoms, fever, or pain. IMTs may recur, and occasionally become locally invasive and/or spread (metastasize) to other parts of the body. The underlying cause of IMTs is poorly understood. Some cases have been linked to translocations involving the ALK gene. Treatment involves surgical removal when possible, although there are reports of treatment with oral steroids and radiation therapy. </s>


Input: What causes Inflammatory myofibroblastic tumor ?

Output: What causes inflammatory myofibroblastic tumors? The underlying cause of inflammatory myofibroblastic tumors (IMTs) remains unknown. While some researchers believe it is a true neoplasm, others believe that it represents an immunologic response to an infectious or noninfectious agent. Several associations have been reported between IMT and infections, including: organizing pneumonia Mycobacterium avium intracellulare Corynebacterium equi (a bacteria that affects the lungs) Campylobacter jejuni (a common cause of gastroenteritis) Bacillus sphaericus Coxiella burnetii Epstein-Barr virus E. coli occlusive phlebitis of intrahepatic veins Associations have also been reported between IMT and: previous abdominal surgery trauma ventriculoperitoneal shunt radiation therapy steroid usage An inflammatory reaction to an underlying, low-grade malignancy has also been proposed as a cause. Because there is limited information available to support or refute any of these, the mechanism behind the development of IMTs is still unclear. </s>


Input: What is (are) 16q24.3 microdeletion syndrome ?

Output: 16q24.3 microdeletion syndrome is a chromosome abnormality that can affect many parts of the body. People with this condition are missing a small piece (deletion) of chromosome 16 at a location designated q24.3. Signs and symptoms may include developmental delay, characteristic facial features, seizures and autism spectrum disorder. Chromosome testing of both parents can provide more information on whether or not the microdeletion was inherited. In most cases, parents do not have any chromosomal anomaly. However, sometimes one parent has a balanced translocation where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause any signs or symptoms, but it increases the risk for having an affected child with a chromosomal anomaly like a microdeletion. Treatment is based on the signs and symptoms present in each person. To learn more about chromosomal anomalies in general, please visit our GARD webpage on Chromosome Disorders. </s>
