<s>[INST] What are the symptoms of Richieri Costa Da Silva syndrome ? [/INST] What are the signs and symptoms of Richieri Costa Da Silva syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Richieri Costa Da Silva syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Absent tibia - Autosomal recessive inheritance - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. 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. </s>

<s>[INST] What is (are) Myocarditis ? [/INST] Myocarditis is a condition that is characterized by inflammation of the heart muscle (myocardium). Some affected people have no noticeable symptoms of the condition. When present, signs and symptoms may include chest pain, abnormal heartbeat, shortness of breath, fatigue, signs of infection (i.e. fever, headache, sore throat, diarrhea), and leg swelling. Myocarditis can be caused by a variety of factors including infections (viral, bacterial, parasitic, and fungal), allergic reactions to certain medications, and exposure to certain chemicals. It can also be associated with other inflammatory conditions such as lupus, Wegener's granulomatosis, giant cell arteritis and Takayasu's arteritis. Most cases occur sporadically in people with no family history of the condition. Treatment aims to address the underlying cause of the condition. Medications and rarely, a heart transplant may be needed if the heart muscle becomes weak. </s>

<s>[INST] What is (are) Abdominal aortic aneurysm ? [/INST] Abdominal aortic aneurysms (AAAs) are aneurysms that occur in the part of the aorta that passes through the abdomen. They may occur at any age, but are most common in men between 50 and 80 years of age. Many people with an AAA have no symptoms, but some people have a pulsing sensation in the abdomen and/or pain in the back. If the aneurysm ruptures, it may cause deep, severe pain; nausea; vomiting; fast heart rate; clammy skin; and/or shock. About 20% of AAAs eventually rupture and are often fatal. The condition has multiple genetic and environmental risk factors, and may sometimes occur as part of an inherited syndrome. When more than one family member is affected, it may be considered "familial abdominal aortic aneurysm." Treatment depends on the size of the aneurysm and may include blood pressure medications, or surgery to repair the aneurysm. </s>

<s>[INST] Is Abdominal aortic aneurysm inherited ? [/INST] 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. </s>

<s>[INST] What is (are) Limb-girdle muscular dystrophy type 2A ? [/INST] Limb-girdle muscular dystrophy type 2A (LGMD2A) is an autosomal recessive limb-girdle muscular dystrophy characterized by progressive, symmetrical weakness of the proximal limb and girdle muscles (mainly those around the hips and shoulders) without cardiac involvement or intellectual disability. The condition is caused by mutations in the CAPN3 gene. Type 2A is the most common form of limb-girdle muscular dystrophy, accounting for about 30 percent of cases. Treatment is aimed at maintaining mobility and preventing complications. There are three subtypes of LGMD2A which differ by the distribution of muscle weakness and age at onset: Pelvifemoral limb-girdle muscular dystrophy (also known as Leyden-Mobius LGMD) is the most frequently observed subtype. In these cases, muscle weakness is first evident in the pelvic girdle and later in the shoulder girdle. Onset is usually before age 12 or after age 30; Scapulohumeral LGMD (also known as Erb LGMD) usually has milder symptoms with infrequent early onset. In most cases, muscle weakness is first evident in the shoulder girdle and later in the pelvic girdle; HyperCKemia is usually observed in children or young individuals. In most cases, those affected don't have symptoms, just high levels of creatine kinase in their blood. </s>

<s>[INST] What is (are) Mantle cell lymphoma ? [/INST] Mantle cell lymphoma (MCL) belongs to a group of diseases known as non-Hodgkins lymphomas (NHL), which are cancers that affect the the lymphatic system (part of the immune system). MCL accounts for 6% of all non-Hodgkin lymphomas and is mostly found in males during their early 60s. Lymphocytes, which are white blood cells that make up the lymphatic system. There are two main types: B-lymphocytes (B-cells) and T-lymphocytes (T-cells). Mantel cell lymphoma is a B-cell lymphoma that develops from cancerous B-cells within a region of the lymph node known as the mantle zone. Although mantle cell lymphomas are slow-growing cancers, at the time of diagnosis, they are usually widespread in the lymph nodes and require intensive treatment because they can become lethal within a short period of time. </s>

<s>[INST] What causes Mantle cell lymphoma ? [/INST] What causes Mantle cell lymphoma? Most lymphomas are not inherited, but rather an acquired disease in which the DNAwithin the cells has been damaged. Damage to the DNA occurs by a combination of different factors. Many mantle cell lymphomas are found to be associated with a chromsosome translocation. Some causes of non-Hodgkin lymphomas (NHL) have been linked to viral infections including Ebstein-Barr virus, HIV, and human herpesvirus 6. It has also been found that immunodeficiencies and environmental factors like hair dyes and pesticides may lead to NHLs. </s>

<s>[INST] How to diagnose Mantle cell lymphoma ? [/INST] How is Mantle cell lymphoma diagnosed? Mantle cell lymphoma is diagnosed by a biopsy (surgical removal) of the lymph nodes. If lymph nodes are not easily accessible to be biopsied, a fine needle aspiration may be performed, but the diagnosis will not be definite. Chromosome translocations in Mantle cell lymphoma can be found by genetic molecular testing methods such as PCR and FISH. </s>

<s>[INST] What is (are) Linear porokeratosis ? [/INST] Linear porokeratosis is a skin condition that most often begins in infancy or early childhood, but it can occur at any age. The main feature of this condition is the development of reddish brown, slightly raised markings on the skin arranged in lines or streaks on one side of the body. These markings are not usually painful, though they can sometimes cause open sores in the skin. There is up to an 11% chance that these markings could progress to skin cancer (basal cell cancer or squamous cell carcinoma) over time. The exact cause of linear porokeratosis is unknown, but risk factors may include exposure to the sun or radiation, problems with the immune system (immunosuppression), or genetic predisposition. </s>

<s>[INST] What are the treatments for Linear porokeratosis ? [/INST] How might linear porokeratosis be treated? Because linear porokeratosis is a rare condition, there is no established treatment protocol. Protection from sun exposure and regular visits to a doctor to check for skin cancer are encouraged as routine care. Treatment options depend on the size, location, and severity of the characteristic skin markings. Several medications (5-fluorouracil, acitretin) have been shown to be effective for treating this condition in a small number of patients. We identified a single report of photodynamic therapy being used to successfully treat an individual with linear porokeratosis. Surgery is recommended to remove any skin cancer that may develop. </s>

EN is a type of inflammatory disorder affecting the layer of fat under the skin (panniculitis). Other symptoms that may accompany the skin findings include the following: fever, a general feeling of being ill. joint aches, and swelling of the affected area. In many cases, EN is presumed to be a delayed reaction to antigens associated with various infections, drugs, and certain systemic diseases. In many cases, however, EN has no identifiable cause (idiopathic); in these cases, clinical follow-up is needed to rule out certain conditions including inflammatory bowel disease, sarcoidosis, lymphoma, and Behcet's disease. Treatment may include rest, nonsteroidal anti-inflammatory drugs (NSAIDS), steroids, hot or cold compresses, potassium iodide solution, and supportive bandages or compression stockings.

<s>[INST] What is (are) Epithelial basement membrane corneal dystrophy ? [/INST] Epithelial basement membrane corneal dystrophy is a condition where the epithelium of the cornea (the outermost region of the cornea) loses its normal clarity due to a buildup of cloudy material. It gets its name from the unusual appearance of the cornea during an eye exam. This dystrophy occurs when the epithelium's basement membrane develops abnormally, causing the epithelial cells to not properly adhere to it. This leads to recurrent epithelial erosions, which can cause blurred vision and severe pain. This condition is usually not inherited. However, families with autosomal dominant inheritance and mutations in the TGFBI gene have been identified. </s>

<s>[INST] What are the symptoms of Epithelial basement membrane corneal dystrophy ? [/INST] What are the signs and symptoms of Epithelial basement membrane corneal dystrophy? A chronic problem seen in this condition is the epithelial erosions. They can alter the cornea's normal curvature, causing periodic blurred vision. These erosions may also expose the nerve endings that line the tissue, resulting in moderate to severe pain lasting as long as several days. Generally, the pain will be worse upon awakening in the morning. Other symptoms include sensitivity to light, excessive tearing, and foreign body sensation in the eye. This condition usually affects adults between the ages of 40 and 70, although it can develop earlier in life. It gets its name from the unusual appearance of the cornea during an eye exam. Most often, the affected epithelium will have a map-like appearance, i.e., large, slightly gray outlines that look like a continent on a map. There may also be clusters of opaque dots close to the map-like patches. Less frequently, the irregular basement membrane will form concentric lines in the central cornea that resemble small fingerprints. Epithelial basement membrane corneal dystrophy is not a progressive condition. Typically, it will flare up occasionally for a few years and then go away on its own, with no lasting loss of vision. Most people never know that they have this condition, since they do not have any pain or vision loss.

<s>[INST] What are the treatments for Epithelial basement membrane corneal dystrophy ? [/INST] How might epithelial basement membrane corneal dystrophy be treated? Because most people do not develop noticeable signs or symptoms, treatment usually is not necessary. However, if treatment is needed, doctors will try to control the pain associated with the epithelial erosions. They may patch the eye to immobilize it, or prescribe lubricating eye drops and ointments. With treatment, these erosions usually heal within three days, although periodic flashes of pain may occur for several weeks thereafter. Other treatments include anterior corneal punctures to allow better adherence of cells; corneal scraping to remove eroded areas of the cornea and allow regeneration of healthy epithelial tissue; and use of the excimer laser to remove surface irregularities.

Signs and symptoms of an aura vary, but may include: Dizziness and vertigo Disorientation Double vision and other visual changes Tinnitus Loss of balance Confusion Dysarthria Fainting Loss of consciousness These symptoms can last any where from two minutes to over an hour. They are then followed by a throbbing headache which is often along the back of the head and nausea. </s>

<s>[INST] What causes Basilar migraine ? [/INST] What causes a basilar migraine? The exact underlying cause of basilar migraines is not well understood. Basilar migraines, like all types of migraines, are likely complex disorders that are influenced by multiple genes in combination with lifestyle and environmental factors. Scientists also suspect that nerve abnormalities and/or altered blood flow to certain parts of the brain (brainstem and occipital lobes, specifically) may also play a role in the development of basilar migraines. The susceptibility to basilar migraines may rarely be caused by a change (mutation) in the ATP1A2 gene or CACNA1A gene. In these cases, episodes of basilar migraines may occur in more than one family member. </s>

<s>[INST] Is Basilar migraine inherited ? [/INST] Are basilar migraines inherited? In most cases, basilar migraines are not inherited. However, the susceptibility to basilar migraines may rarely be caused by a change (mutation) in the ATP1A2 gene or CACNA1A gene. In these cases, they are inherited in an autosomal dominant manner. This means that to be affected, a person only needs a mutation in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with one of these mutations has a 50% chance with each pregnancy of passing along the altered gene to his or her child. </s>

<s>[INST] How to diagnose Basilar migraine ? [/INST] How is a basilar migraine diagnosed? A diagnosis of basilar migraine is made based on the presence of characteristic signs and symptoms. Although there are no tests available to confirm the diagnosis, additional testing may be ordered to rule out other conditions that can cause similar features. These tests may include: Brain MRI MR angiogram (MRA) Electroencephalogram 24-hour heart monitor Specialized blood tests </s>

<s>[INST] What are the treatments for Basilar migraine ? [/INST] How are basilar migraines treated? During episodes of basilar migraines, people are generally treated with nonsteroidal anti-inflammatory drugs (NSAIDs) and antiemetic medications to help alleviate the symptoms. In some cases, a nerve block can be used to treat pain if other therapies are ineffective. In people with episodes of basilar migraines that are frequent, prolonged, or particularly debilitating, certain medications such as verapamil or topiramate may be prescribed as a preventative therapy. </s>

<s>[INST] What is (are) Mitochondrial DNA-associated Leigh syndrome ? [/INST] Mitochondrial DNA-associated Leigh syndrome is a progressive brain disorder that usually appears in infancy or early childhood. Affected children may experience vomiting, seizures, delayed development, muscle weakness, and problems with movement. Heart disease, kidney problems, and difficulty breathing can also occur in people with this disorder. Mitochondrial DNA-associated Leigh syndrome is a subtype of Leigh syndrome and is caused by changes in mitochondrial DNA. Mutations in at least 11 mitochondrial genes have been found to cause mtDNA-associated Leigh syndrome. This condition has an inheritance pattern known as maternal or mitochondrial inheritance. Because mitochondria can be passed from one generation to the next only through egg cells (not through sperm cells), only females pass mitochondrial DNA-associated Leigh syndrome to their children. </s>

<s>[INST] What is (are) Central core disease ? [/INST] Central core disease (CCD) is an inherited condition that involves muscle weakness, skeletal abnormalities, and an increased chance of having a severe reaction to some anesthesia medications. Muscle weakness ranges from mild to severe and typically affects muscles in the trunk and upper legs, though muscles in the neck and face can also be affected. Skeletal abnormalities may include curving of the spine (scoliosis), dislocation of the hip, or restricted motion in certain joints (contractures). Some individuals with CCD have an increased chance of having a severe reaction to anesthesia, called malignant hyperthermia, which may cause muscle rigidity or break-down (rhabdomyolysis), a high fever, or a rapid heart beat. RYR1 is the only gene associated with CCD and clinical testing is available to look for disease-causing alterations in this gene known as mutations. </s>

<s>[INST] What are the treatments for Central core disease ? [/INST] What treatments might be available for central core disease? Treatments for central core disease (CCD) depend on the symptoms experienced by each affected individual. When someone is first diagnosed with this condition, a physical examination is done to assess the extent and severity of muscle weakness, and physical therapy and occupational therapy assessments to determine which therapies might be most beneficial. Physical therapy, such as stretching or low-impact exercises, may help improve weakness. Some skeletal abnormalities can be addressed with physical therapy, though others may require surgery. As the muscle weakness and scoliosis associated with CCD can affect breathing, individuals diagnosed with this condition may benefit from pulmonary function tests. If breathing is significantly affected, breathing exercises or other breathing support treatments may be recommended. Another treatment option may be a medication called salbutamol, which was found to significantly increased muscle strength and stamina in six of eight children with CCD. </s>

<s>[INST] What causes Currarino triad ? [/INST] What causes Currarino triad? Currarino triad is caused by mutations in the MNX1 gene in nearly all familial and 30% of sporadic cases. These mutations in the gene are called loss of function mutations because the gene can no longer produce working (functional) protein. Less frequently, a complex phenotype of Currarino triad can be caused by microdeletions of 7q containing MNX1 (the long arm of chromosome 7 is missing a small piece of DNA which includes MNX1 and other genes). </s>

<s>[INST] Is Currarino triad inherited ? [/INST] How is Currarino triad inherited? Currarino triad is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one copy of the MNX1 gene in each cell is enough to cause features of the condition. In some cases, an affected person inherits the mutated gene from an affected parent. In other cases, the mutation occurs for the first time in a person with no family history of the condition. This is called a de novo mutation. When a person with a mutation that causes an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit that mutation. A significant interfamilial (between different families) and intrafamilial (within the same family) variability in expression has been found without any definite correlation to the genetic mutations. This means in one family, a parent might only have one very mild feature of Currarino triad while one of their children might have severe forms of all three features and yet another child might have a mild form of one feature and a severe form of another. </s>

<s>[INST] What is (are) Tracheobronchomalacia ? [/INST] Tracheobronchomalacia (TBM) is a rare condition that occurs when the walls of the airway (specifically the trachea and bronchi) are weak. This can cause the airway to become narrow or collapse. There are two forms of TBM: a congenital form (called primary TBM) that typically develops during infancy or early childhood and an acquired form (called secondary TBM) that is usually seen in adults. Some affected people may initially have no signs or symptoms. However, the condition is typically progressive (becomes worse overtime) and most people will eventually develop characteristic features such as shortness of breath, cough, sputum retention (inability to clear mucus from the respiratory tract), and wheezing or stridor with breathing. Most cases of primary TBM are caused by genetic conditions that weaken the walls of the airway, while the secondary form often occurs incidentally due to trauma, chronic inflammation and/or prolonged compression of the airways. Treatment is generally only required in those who have signs and symptoms of the condition and may include stenting, surgical correction, continuous positive airway pressure (CPAP), and tracheostomy. </s>

For example, TBM has been reported in people with mucopolysaccharidoses (such as Hunter syndrome and Hurler syndrome), Ehlers-Danlos Syndrome, and a variety of chromosome abnormalities. Primary TBM can also be idiopathic (unknown cause) or associated with prematurity and certain birth defects (i.e. tracheoesophageal fistula). The secondary form (also called acquired TBM) is caused by the degeneration (break down) of cartilage that typically supports the airways. It is most commonly associated with: Certain medical procedures such as endotracheal intubation or tracheostomy Conditions that lead to chronic (persisting or progressing for a long period of time) inflammation such as relapsing polychondritis or chronic obstructive pulmonary disease (COPD) Cancers, tumors, or cysts that cause prolonged compression of the airway </s>

TBM is considered mild if the trachea narrows to 50% of its initial size while the affected person is breathing out, moderate if it narrows to 25%, and severe if the walls of the trachea touch. </s>

<s>[INST] What are the treatments for Tracheobronchomalacia ? [/INST] How might tracheobronchomalacia be treated? Treatment is only medically necessary in people who have signs and symptoms of tracheobronchomalacia (TBM). Management of symptomatic TBM first involves identifying underlying conditions contributing to symptoms, such as chronic inflammation, compression, or injury. Initial treatment will target these underlying medical concerns. If symptoms persist, people with TBM may undergo pulmonary function tests or other assessments to help guide therapy choice and allow monitoring of the response to treatment. Treatment options may include: Silicone and/or long-term stenting Surgical correction Continuous positive airway pressure (CPAP) Tracheostomy (often used as a last resort as it can sometimes worsen TBM) We strongly recommend that you discuss your treatment options with a healthcare provider. </s>

<s>[INST] What is (are) Amelogenesis imperfecta ? [/INST] 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. </s>

<s>[INST] What are the symptoms of Amelogenesis imperfecta ? [/INST] What are the signs and symptoms of amelogenesis imperfecta? In general, the both primary and permanent teeth are affected. The enamel tends to be soft and weak, and the teeth appear yellow and damage easily. The defects associated with amelogeneis imperfecta are highly variable and include abnormalities classified as hypoplastic (defects in the amount of enamel), hypomaturation (defect in the final growth and development of the tooth enamel), and hypocalcification (defect in the initial stage of enamel formation followed by defective tooth growth). The enamel in the hypomaturation and hypocalcification types is not mineralized and is thus described as hypomineralized. Traditionally, the diagnosis and classification of amelogenesis imperfecta is based on the clinical presentation and the mode of inheritance. There are four principal types based on the defects in the tooth enamel. These types are subdivided into 14 different subtypes based on the clinical presentation and the mode of inheritance. Detailed information about the signs and symptoms associated with the four major types of amelogenesis imperfecta is available from the UNC School of Dentistry. </s>

<s>[INST] What causes Amelogenesis imperfecta ? [/INST] What causes amelogenesis imperfecta? Amelogenesis imperfecta is caused by mutations in the AMELX, ENAM, and MMP20 genes. These genes provide instructions for making proteins that are essential for normal tooth development. These proteins are involved in the formation of enamel, which is the hard, calcium-rich material that forms the protective outer layer of each tooth. Mutations in any of these genes alter the structure of these proteins or prevent the genes from making any protein at all. As a result, tooth enamel is abnormally thin or soft and may have a yellow or brown color. Teeth with defective enamel are weak and easily damaged. In some cases, the genetic cause of amelogenesis imperfecta can not been identified. Researchers are working to find mutations in other genes that are responsible for this disorder.

Amelogenesis imperfecta can have different patterns of inheritance, depending on the gene that is altered. Most cases are caused by mutations in the ENAM gene and are inherited in an autosomal dominant pattern. This type of inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Amelogenesis imperfecta may also be inherited in an autosomal recessive pattern; this form of the disorder can result from mutations in the ENAM or MMP20 gene. Autosomal recessive inheritance means two copies of the gene in each cell are altered. About 5 percent of amelogenesis imperfecta cases are caused by mutations in the AMELX gene and are inherited in an X-linked pattern. 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. In most cases, males with X-linked amelogenesis imperfecta experience more severe dental abnormalities than females with this form of this condition. Other cases of amelogenesis imperfecta result from new mutations in these genes and occur in people with no history of the disorder in their family. </s>

<s>[INST] How to diagnose Amelogenesis imperfecta ? [/INST] How is amelogenesis imperfecta diagnosed? A dentist can identify and diagnose amelogenesis imperfecta on the basis of the patient's family history and the signs and symptoms present in the affected individual. Extraoral X-rays (X-rays taken outside the mouth) can reveal the presence of teeth that never erupted o that were absorbed. Intraoral X-rays (X-rays taken inside the mouth) show contrast between the enamel and dentin in cases in which mineralization is affected. Genetic testing is available for the genes AMELX, ENAM, and MMP20. You can visit the Genetic Testing Registry to locate laboratories performing genetic testing for these genes. The American Academy of Pediatric Dentistry is a source of information to find a pediatric dentist. The National Dental Association can also assist people in locating a dentist. </s>

<s>[INST] What are the treatments for Amelogenesis imperfecta ? [/INST] How might amelogenesis imperfecta be treated? Treatment depends on the type of amelogenesis imperfecta and the type of enamel abnormality. Treatments include preventative measures, various types of crowns, as well as tooth implants or dentures in the most severe cases. The social and emotional impact of this condition should also be addressed. Detailed information on the treatment of amelogenesis imperfecta is available from the UNC School of Dentistry. </s>

<s>[INST] What is (are) Von Hippel-Lindau disease ? [/INST] Von Hippel-Lindau (VHL) disease is an inherited disorder characterized by the abnormal growth of both benign and cancerous tumors and cysts in many parts of the body. Tumors usually first appear in young adulthood. The types of tumors associated with VHL disease include hemangioblastomas (slow-growing tumors of the central nervous system); kidney cysts and clear cell renal cell carcinoma; pancreatic neuroendocrine tumors; pheochromocytomas (noncancerous tumors of the adrenal glands); and endolymphatic sac tumors. VHL disease is caused by a mutation in the VHL gene and is inherited in an autosomal dominant manner. Early detection and treatment of VHL disease is important, and usually involves surgical removal of tumors. </s>

<s>[INST] What are the symptoms of Von Hippel-Lindau disease ? [/INST] What are the signs and symptoms of Von Hippel-Lindau disease? Symptoms of Von Hippel-Lindau (VHL) disease vary among patients and depend on the size and location of the tumors. Hemangioblastomas that develop in the brain and spinal cord can cause headaches, vomiting, weakness, and a loss of muscle coordination (ataxia). Hemangioblastomas can also occur in the light-sensitive tissue that lines the back of the eye (the retina). These tumors, which are also called retinal angiomas, may cause vision loss. Pheochromocytomas affect the adrenal glands, which are small hormone-producing glands located on top of each kidney. These tumors often cause no symptoms, but in some cases they can produce an excess of hormones that cause dangerously high blood pressure. About 10 percent of people with VHL disease develop endolymphatic sac tumors, which are noncancerous tumors in the inner ear. These growths can cause hearing loss in one or both ears, as well as ringing in the ears (tinnitus) and problems with balance. Individuals with VHL disease are also at a higher risk than normal for certain types of cancer, especially kidney cancer. Renal cell carcinoma occurs in about 70% of individuals with VHL disease by age 60 and is the leading cause of mortality.

<s>[INST] What causes Von Hippel-Lindau disease ? [/INST] What causes Von Hippel-Lindau disease? Von Hippel-Lindau (VHL) disease is caused by a mutation in the VHL gene. This gene is a tumor suppressor gene, which helps to control cell growth. Mutations in the VHL gene lead to a lack of regulation of cell growth and survival, allowing cells to grow and divide uncontrollably, forming the tumors that are associated with VHL disease. </s>

<s>[INST] Is Von Hippel-Lindau disease inherited ? [/INST] How is von Hippel-Lindau (VHL) disease inherited? Mutations in the gene that causes VHL disease (the VHL gene) are inherited in an autosomal dominant manner. This means that having a mutation in only one copy of the VHL gene in each cell is enough to increase a person's risk of developing VHL disease. In most autosomal dominant conditions, having one mutated copy of the responsible gene is sufficient to cause the condition. However, in VHL disease, a mutation in the other copy of the gene must occur (during a person's lifetime) to trigger the development of VHL disease. For example, a person may inherit a mutated copy of the gene from a parent, but acquiring a second mutation in the other gene copy in a specific organ may trigger tumor development in that organ. Almost everyone who is born with one VHL mutation will eventually acquire a mutation in the second copy of the gene and develop VHL disease. In most cases, an affected person inherits the first mutated gene from an affected parent. However, in about 20% of cases, the mutation occurs for the first time in a person with no family history of the condition. This is called a de novo mutation. When a person with a mutation that can lead to VHL disease has children, each of their children has a 50% (1 in 2) chance to inherit that mutation. </s>

DPL is often associated with uterine leiomyomas but the connection is unclear. Most cases occur sporadically in people with no family history of the condition; however, more than one family member can be affected. Although this suggests that genetic factors may play a role in the development of DPL in some families, researchers have not identified any specific gene changes known to cause the condition.The cause of the condition is considered multifactorial . </s>

<s>[INST] How to diagnose Disseminated peritoneal leiomyomatosis ? [/INST] How is disseminated peritoneal leiomyomatosis (DPL) diagnosed? An ultrasound may reveal the presence of nodules (lumps) which may indicate disseminated peritoneal leiomyomatosis (DPL). However, DPL can only be confirmed by a biopsy of the nodule. The nodules should contain smooth muscle cells with no atypia (no abnormal structure) or necrosis (dead cells). The cells usually have both progesterone and estrogen receptors, but this is not always the case. The cells usually have a low mitotic index (meaning they are not dividing at a high rate). </s>

<s>[INST] What are the treatments for Disseminated peritoneal leiomyomatosis ? [/INST] How might disseminated peritoneal leiomyomatosis (DPL) be treated? Presently there are no treatment guidelines for disseminated peritoneal leiomyomatosis (DPL). DPL is considered a benign condition and some cases of DPL resolve after the baby is delivered (if pregnant), hormone treatment is stopped (including both birth control pill and hormone replacement therapy), or a hormone producing tumor is removed. However, surgery may be suggested based on the size and location of the tumor. </s>

<s>[INST] What is (are) Meningoencephalocele ? [/INST] Meningoencephalocele is a type of encephalocele, which is an abnormal sac of fluid, brain tissue, and meninges (membranes that cover the brain and spinal cord) that extends through a defect in the skull. There are two main types of meningoencephalocele, which are named according to the location of the sac. The frontoethmoidal type is located at the frontal and ethmoid bones while the occipital type is located at the occipital bone. Hydrocephalus, abnormalities of the eyeball and tear duct, and other findings have been associated with the condition. Some affected individuals have intellectual or physical disabilities while others have normal development and abilities. The condition is typically congenital (present at birth) but has been reported to develop by chance in older individuals in rare cases. The underlying cause of the condition is uncertain, but environmental factors are thought to play a role. Treatment depends on the size, location and severity of the defect but mainly includes magnetic resonance imaging (MRI) to determine the severity of the defect, followed by surgery to repair it. </s>

<s>[INST] What causes Meningoencephalocele ? [/INST] What causes meningoencephalocele? The exact cause of meningoencephalocele is not known. Some studies have suggested that environmental factors could play a role in causing the condition. Exposure during pregnancy to aflatoxins, toxins produced by a mold that grows in nuts, seeds, and legumes, has been proposed to be a possible cause in some cases. However, its potential role in causing the condition is unclear. It has also been suggested that folate deficiency during pregnancy might play a role, because the condition is so closely related to spina bifida, which can be caused by folate deficiency. However, there have been no studies regarding the relationship of maternal folate deficiency and meningoencephalocele. Further studies are needed to to clarify what may cause the condition. </s>

<s>[INST] Is Meningoencephalocele inherited ? [/INST] Is meningoencephalocele inherited? Meningoencephalocele is not thought to be an inherited condition. Studies have proposed that meningoencephalocele is likely a multifactorial defect. This means that both environmental factors and multiple genes may interact with each other to cause the condition. Studies have suggested that environmental factors probably play an important role. This information is supported by the fact that several studies have not identified the condition among close relatives of affected individuals. To date, there have been no genes identified that are likely to play a strong part in causing the condition. </s>

Treatment is symptomatic and may include pain relievers and physical therapy. </s>

<s>[INST] What are the symptoms of Parsonage Turner syndrome ? [/INST] What are the signs and symptoms of Parsonage Turner syndrome? Parsonage Turner syndrome is usually characterized by the sudden onset of severe pain in the shoulder and upper arm, which is often described as sharp or throbbing. In some cases, the pain may extend to the neck, lower arm and/or hand on the affected side. Rarely, both sides of the body are involved. Affected people typically experience constant pain that may become worse with movement. Intense pain can last from a few hours to several weeks at which point the pain usually begins to subside; however, mild pain may continue for a year or longer. As the pain subsides, it is typically replaced by progressive (worsening over time) weakness of the affected area, ranging from mild weakness to nearly complete paralysis. Affected people may also experience muscle wasting (atrophy); absent or reduced reflexes; and/or loss of sensation. In some cases, nerves and muscles outside of the shoulder and upper arm region may be affected, as well. </s>
