<s>[INST] What are the treatments for Benign multicystic peritoneal mesothelioma ? [/INST] How might benign multicystic peritoneal mesothelioma be treated? Surgery to remove the cystic lesions is the only effective treatment for BMPM. Aggressive surgical approaches are often recommended. Hormonal therapy has also been attempted in individual cases with variable degrees of success. Most affected individuals do not undergo chemotherapy and/or radiotherapy because these tumors are usually benign. </s></s>

<s>[INST] What is (are) Moyamoya disease ? [/INST] Moyamoya disease is a rare, progressive, blood vessel disease caused by blocked arteries at the base of the brain in an area called the basal ganglia. The name "moyamoya" means "puff of smoke" in Japanese and describes the look of the tangled vessels that form to compensate for the blockage. This condition usually affects children, but can affect adults. Affected people are at increased risk for blood clots, strokes, and transient ischemic attacks (TIAs) which are frequently accompanied by seizures and muscular weakness, or paralysis on one side of the body. Affected people may also have disturbed consciousness, speech deficits (usually aphasia), sensory and cognitive impairments, involuntary movements, and vision problems. Researchers believe that Moyamoya disease is an inherited condition because it tends to run in families. Moyamoya syndrome is a related term that refers to cases of moyamoya disease that occur in association with other conditions or risk factors, such as neurofibromatosis, tuberculosis meningitis, sickle cell disease, leptospirosis, brain tumors, Sturge-Weber syndrome, and tuberous sclerosis. </s></s>

<s>[INST] What causes Moyamoya disease ? [/INST] What causes Moyamoya disease? In some families, risk for moyamoya disease is inherited. Changes in the RNF213 gene have been associated with the condition. There are other gene changes involved in moyamoya disease, that remain to be found. Factors such as infection or inflammation, likely also play a role in the condition's development in these families. Other people develop moyamoya syndrome or phenomenon. Moyamoya syndrome can occur in association with many different conditions, such as with infections, atherosclerosis (clogged arteries), blood disorders (for example sickle cell disease or beta thalassemia), vasculitis, autoimmune conditions (for example Lupus, thyroid disorders, Sneddon syndrome), connective tissue disorders (for example neurofibromatosis (NF) type 1 or Tuberous sclerosis), chromosome disorders, metabolic diseases, head trauma or radiation, brain tumors, and heart disease, to name a few. </s></s>

<s>[INST] What are the treatments for Moyamoya disease ? [/INST] How might Moyamoya disease be treated? Treatment for Moyamoya disease should begin early in the disease course to prevent severe complications. Surgery is the mainstay of treatment, and is the only viable long-term treatment. There are several types of revascularization surgeries that can restore blood flow to the brain by opening narrowed blood vessels, or by bypassing blocked arteries. While children usually respond better to revascularization surgery than adults, the majority of individuals have no further strokes or related problems after surgery. No medication can stop the narrowing of the brain's blood vessels, or the development of the thin, fragile vessels that characterize the disease. However, medications are used to treat many of the symptoms of the disease, and are often an important part of the management. Medications may include aspirin (to prevent or reduce the development of small blood clots); calcium channel blockers (which may improve symptoms of headaches and reduce symptoms related to transient ischemic attacks); and anti-seizure medications (when needed for a seizure disorder). In a few cases, anticoagulants may be needed for people with unstable or frequent symptoms. However, they are not used long-term due to the risk of cerebral bleeding. Additional information about the treatment of Moyamoya disease is available on Medscape Reference's Web site. People interested in learning about specific treatment options for themselves or family members should speak with their health care provider. </s></s>

<s>[INST] What are the symptoms of Gorham's disease ? [/INST] What are the signs and symptoms of Gorham's disease? Most cases of Gorham's disease are discovered before the age of 40. Symptoms vary among affected people and depend on the area of the body involved. The most commonly involved sites are the skull, jaw, shoulder, rib cage, and pelvis. The degree of complications ranges from mild to severe, or even life-threatening. In some cases, affected people may rapidly develop pain and swelling in the affected area, or a fracture on the affected site. Others may experience a dull pain or ache, limitation of motion, or generalized weakness that builds over time. Some people don't have any symptoms. Complications from Gorham's disease may occur when fluids build-up in the space between the membrane that surround each lung and line the chest cavity (pleural effusion).

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

Insulin resistance is a condition in which the body produces insulin but does not use it properly. This causes the pancreas to produce more insulin. High levels of insulin stimulate the ovaries to make too much androgen, leading too excessive hair growth, acne, and irregular periods. Insulin resistance can also lead to diabetes, high blood pressure, heart disease, and excessive growth and darkening of the skin (aconthosis nigricans).

The most common internal site involved is the gastrointestinal tract (with almost half of affected people having colorectal cancer), followed by the genitourinary tract. Skin lesions may develop before or after the diagnosis of the internal cancer. MTS is caused by changes (mutations) in the MLH1 or MSH2 genes and is inherited in an autosomal dominant manner. A mutation in either of these genes gives a person an increased lifetime risk of developing the skin changes and types of cancer associated with the condition. </s></s>

Sebaceous adenoma is the most characteristic finding in people with Muir-Torre syndrome (MTS). Other types of skin tumors in affected people include sebaceous epitheliomas, sebaceous carcinomas (which commonly occur on the eyelids) and keratoacanthomas. Sebaceous carcinoma of the eyelid can invade the orbit of the eye and frequently metastasize, leading to death. Tumors at other sites can also metastasize, but are less likely to cause death. Common sites of keratocathomas include the face and the upper side of the hands, but they can occur anywhere on the body. The most common internal cancer in people with MTS is colorectal cancer, occurring in almost half of affected people. The second most common site is the genitourinary tract.

<s>[INST] What causes Muir-Torre syndrome ? [/INST] What causes Muir-Torre syndrome? Muir-Torre syndrome is a subtype of Lynch syndrome and may be caused by changes (mutations) in either the MLH1, MSH2, or MSH6 gene. These genes give the body instructions to make proteins needed for repairing DNA. The proteins help fix mistakes that are made when DNA is copied before cells divide. When one of these genes is mutated and causes the related protein to be absent or nonfunctional, the number of DNA mistakes that do not get repaired increases substantially. The affected cells do not function normally, increasing the risk of tumor formation. The MSH2 gene is responsible for MTS in the majority of cases. Mutations in MLH1 and MSH2 have the most severe effect. Not everyone diagnosed with MTS will have a detectable mutation in one of these genes. Other, unidentified genes may also play a role in the development of the condition. </s></s>

<s>[INST] Is Muir-Torre syndrome inherited ? [/INST] How is Muir-Torre syndrome inherited? Muir-Torre-syndrome (MTS) is a variant of Lynch syndrome and is inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough for a person to develop the condition. When a person with an autosomal dominant condition has children, each child has 50% (1 in 2) chance to inherit the mutated copy of the responsible gene. It is important to note that people who inherit a mutated gene that causes MTS inherit an increased risk of cancer, not the disease itself. Not all people who inherit a mutation in an associated gene will develop cancer. This phenomenon is called reduced penetrance. The majority of people diagnosed with a form of Lynch syndrome have inherited the mutated gene from a parent. However, because not all people with a mutation develop cancer, and the variable age at which cancer may develop, not all people with a mutation have a parent who had cancer. Thus, the family history may appear negative. A positive family history of MTS is identified in roughly 50% of affected people. The percentage of people with Lynch syndrome who have a new mutation in the gene that occurred for the first time (and was not inherited from a parent) is unknown but is estimated to be extremely low. </s></s>

<s>[INST] How to diagnose Muir-Torre syndrome ? [/INST] How is Muir-Torre syndrome diagnosed?

A person diagnosed with MTS can also have genetic testing to see if they have a mutation in one of the genes known to cause MTS. However, not everyone with Muir-Torre syndrome will have a detectable mutation in one of these genes. Other, unidentified genes may also play a role in the development of the condition. </s></s>

Affected children often experience delayed development of motor skills (such as crawling and walking), although most eventually acquire these skills. Moebius syndrome is caused by the absence or underdevelopment of the 6th and 7th cranial nerves, which control eye movement and facial expression. Other cranial nerves may also be affected.

Vision often deteriorates early in life, but then usually becomes stable until late adulthood. A second decline in vision typically occurs in a man's fifties or sixties. Sometimes severe complications occur, including separation of the retinal layers (retinal detachment) or leakage of blood vessels in the retina (vitreous hemorrhage). These can lead to blindness. Juvenile retinoschisis is caused by mutations in the RS1 gene. It is inherited in an X-linked recessive pattern. Low-vision aids can be helpful.

<s>[INST] What causes Juvenile retinoschisis ? [/INST] What causes juvenile retinoschisis? Mutations in the RS1 gene cause most cases of juvenile retinoschisis. The RS1 gene provides instructions for producing a protein called retinoschisin, which is found in the retina. Studies suggest that retinoschisin plays a role in the development and maintenance of the retina, perhaps playing a role in cell adhesion (the attachment of cells together). RS1 gene mutations lead to a reduced amount or complete absence of retinoschisin, which can cause tiny splits (schisis) or tears to form in the retina. This damage often forms a "spoke-wheel" pattern in the macula, which can be seen during an eye examination. In about half of individuals, these abnormalities are seen in the area of the macula, affecting visual acuity. In the other half, the sides of the retina are affected, resulting in impaired peripheral vision. Some individuals with juvenile retinoschisis do not have a mutation in the RS1 gene. In these individuals, the cause of the disorder is unknown. </s></s>

<s>[INST] Is Juvenile retinoschisis inherited ? [/INST] How is juvenile retinoschisis inherited? Juvenile retinoschisis is inherited in an x-linked recessive pattern. The gene associated with this condition is located on the X chromosome, one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation must be present in both copies of the gene to cause the disorder. Males are affected by X-linked recessive disorders much more frequently than females. A striking characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. In X-linked recessive inheritance, a female with one mutated copy of the gene (mutation) in each cell is called a carrier. She can pass on the mutation, but usually does not experience signs and symptoms of the condition. Carrier women have a 50% chance of passing the mutation to their children, males who inherit the mutation will be affected; females who inherit the mutation will be carriers and will nearly always have normal vision. Carrier testing for at-risk female relatives and prenatal testing for pregnancies at increased risk are possible if the disease-causing mutation in the family is known. </s></s>

Low vision services are designed to benefit those whose ability to function is compromised by impaired vision. Public school systems are mandated by federal law to provide appropriate education for children who have vision impairment. Surgery may be required to address the infrequent complications of vitreous hemorrhage and retinal detachment. Affected individuals should avoid high-contact sports and other activities that can cause head trauma to reduce risk of retinal detachment and vitreous hemorrhage. </s></s>

There is currently no cure for lipoid proteinosis (LP) of Urbach and Wiethe. Treatment is based on the signs and symptoms present in each person. The skin abnormalities found in people affected by LP may be treated with certain medications, including corticosteriods, dimethyl sulfoxide; or d-penicillamine. An additional medication called acitretin can be used to treat hoarseness and some skin problems. Anticonvulsant medications are often prescribed for people with seizures. The success of these medications in treating the signs and symptoms of LP varies. Affected people with growths on their vocal cords or eyelids may be treated with carbon dioxide laser surgery. Dermabrasion (removal of the top layer of skin) may also improve the appearance of skin abnormalities. </s></s>

<s>[INST] What is (are) Axenfeld-Rieger syndrome type 1 ? [/INST] Axenfeld-Rieger syndrome is a group of eye disorders that affects the development of the eye. Common eye symptoms include cornea defects, which is the clear covering on the front of the eye, and iris defects, which is the colored part of the eye. People with this syndrome may have an off-center pupil (corectopia) or extra holes in the eyes that can look like multiple pupils (polycoria). About 50% of people with this syndrome develop glaucoma, which is a serious condition that increases pressure inside of the eye. This may cause vision loss or blindness. Click here to view a diagram of the eye. Even though Axenfeld-Rieger syndrome is primarily an eye disorder, this syndrome is also associated with symptoms that affect other parts of the body. Most people with this syndrome have distinctive facial features and many have issues with their teeth, including unusually small teeth (microdontia) or fewer than normal teeth (oligodontia). Some people have extra folds of skin around their belly button, heart defects, or other more rare birth defects. There are three types of Axenfeld-Rieger syndrome and each has a different genetic cause. Axenfeld-Rieger syndrome type 1 is caused by spelling mistakes (mutations) in the PITX2 gene. Axenfeld-Rieger syndrome type 3 is caused by mutations in the FOXC1 gene. The gene that causes Axenfeld-Rieger syndrome type 2 is not known, but it is located on chromosome 13. Axenfeld-Rieger syndrome has an autosomal dominant pattern of inheritance. </s></s>

<s>[INST] What is (are) Maternally inherited diabetes and deafness ? [/INST] Maternally inherited diabetes and deafness (MIDD) is a form of diabetes that is often accompanied by hearing loss, especially of high tones. The diabetes in MIDD is characterized by high blood sugar levels (hyperglycemia) resulting from a shortage of the hormone insulin, which regulates the amount of sugar in the blood. MIDD is caused by mutations in the MT-TL1, MT-TK, or MT-TE gene. These genes are found in mitochondrial DNA, which is part of cellular structures called mitochondria. Although most DNA is packaged in chromosomes within the cell nucleus, mitochondria also have a small amount of their own DNA (known as mitochondrial DNA or mtDNA). Because the genes involved with MIDD are found in mitochondrial DNA, this condition is inherited in a mitochondrial pattern, which is also known as maternal inheritance. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, only females pass mitochondrial conditions to their children. Mitochondrial disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass mitochondrial traits to their children. </s></s>

Some people develop symptoms in both ears many years after their initial diagnosis. The exact cause of Mnire's disease is unknown, but the symptoms are thought to be associated with a change in fluid volume within a portion of the inner ear known as the labyrinth. Treatment may include medications or surgery depending on the severity of the condition. </s></s>

<s>[INST] What are the symptoms of Mnire's disease ? [/INST] What are the signs and symptoms of Mnire's disease? The symptoms of Mnire's disease typically occur suddenly and can arise daily, or as infrequently as once a year. Vertigo, often the most debilitating symptom of Mnire's disease, typically involves a whirling dizziness that forces the affected person to lie down. Vertigo attacks can lead to severe nausea, vomiting, and sweating, and often come with little or no warning. Some people with Mnire's disease have attacks that start with tinnitus (ear noises), a loss of hearing, or a full feeling or pressure in the affected ear. It is important to remember that all of these symptoms are unpredictable. Typically, the attack is characterized by a combination of vertigo, tinnitus, and hearing loss lasting several hours. People experience these discomforts at varying frequencies, durations, and intensities. Some may feel slight vertigo a few times a year. Others may be occasionally disturbed by intense, uncontrollable tinnitus while sleeping. Affected people may also notice hearing loss or feel unsteady for prolonged periods. Other occasional symptoms of Mnire's disease may include headaches, abdominal discomfort, and diarrhea. A person's hearing tends to recover between attacks but over time may become worse. Meniere's disease usually starts in one ear but it may extend to involve both ears over time. The Human Phenotype Ontology provides the following list of signs and symptoms for Mnire's disease.

<s>[INST] What causes Mnire's disease ? [/INST] What causes Mnire's disease?

Possible factors that have been studied include viral infections; trauma to the middle ear; middle ear infection (otitis media); head injury; a hereditary predisposition; syphilis; allergies; abnormal immune system responses; migraines; and noise pollution. The symptoms of Mnire's disease are thought to relate to changes in fluid volume in the inner ear, which contains structures necessary for normal hearing and balance. Changes in fluid volume may disrupt signals sent from the inner ear to the brain, or may lead to tears or ruptures of the structures that affect hearing and balance. More detailed information about the causes of symptoms associated with Mnire's disease is available on NIDCD's Web site. </s></s>

<s>[INST] How to diagnose Mnire's disease ? [/INST] How is Mnire's disease diagnosed? The hallmark of Mnire's disease is the fluctuation, waxing and waning of symptoms. Proper diagnosis of Mnire's disease entails several procedures, including a medical history interview; a physical examination; hearing and balance tests; and medical imaging with magnetic resonance imaging (MRI). Accurate measurement and characterization of hearing loss are of critical importance in the diagnosis of Mnire's disease. Through the use of several types of hearing tests, physicians can characterize hearing loss as being sensory (arising from the inner ear) or neural (arising from the hearing nerve). Recording the auditory brain stem response, which measures electrical activity in the hearing nerve and brain stem, is useful in differentiating between these two types of hearing loss. Electrocochleography, recording the electrical activity of the inner ear in response to sound, helps confirm the diagnosis. To test the vestibular or balance system, physicians irrigate the ears with warm and cool water or air. This procedure, known as caloric testing, results in nystagmus, rapid eye movements that can help a physician analyze a balance disorder. Since tumor growth can produce symptoms similar to Mnire's disease, an MRI is a useful test to determine whether a tumor is causing the patient's vertigo and hearing loss. </s></s>

<s>[INST] What are the treatments for Mnire's disease ? [/INST] How might Mnire's disease be treated? At the present time there is no cure for Mnire's disease, but there are several safe and effective medical and surgical therapies that are available to help individuals cope with the symptoms. The symptoms of the disease are often controlled successfully by reducing the bodys retention of fluids through dietary changes (such as a low-salt or salt-free diet and no caffeine or alcohol). Medications such as antihistamines, anticholinergics, and diuretics may lower endolymphatic pressure by reducing the amount of endolymphatic fluid. Eliminating tobacco use and reducing stress levels may also help lessen the severity of symptoms. Symptoms such as dizziness, vertigo, and associated nausea and vomiting may respond to sedative/hypnotics, benzodiazepines like diazepam and anti-emetics. Different surgical procedures are an option for individuals with persistent, debilitating vertigo. Labyrinthectomy (removal of the inner ear sense organ) can effectively control vertigo, but sacrifices hearing and is reserved for patients with nonfunctional hearing in the affected ear. Vestibular neurectomy, selectively severing a nerve from the affected inner ear organ, usually controls the vertigo while preserving hearing but carries surgical risks. Recently, the administration of the ototoxic antibiotic gentamycin directly into the middle ear space has gained popularity worldwide for the control of vertigo associated with Mnire's disease.

<s>[INST] What are the treatments for Trichotillomania ? [/INST] How might trichotillomania be treated? Behavioral treatment seems to be the most powerful treatment for trichotillomania. Parental involvement is important and should include enough support so that affected children grow well intellectually, physically, and socially. Shaving or clipping hair close to the scalp may be helpful to stop the behavior. Professional cognitive behavior therapy (CBT) is recommended if initial approaches are unsuccessful. CBT typically involves self monitoring (keeping records of the behavior); habit-reversal training; and stimulus control (organizing the environment). CBT is typically effective in highly motivated and compliant patients. The success of therapy may depend on firm understanding of the illness and the cooperation of the family members to help the affected individual comply with treatment. Several courses of CBT may be needed. No medication has been approved for the treatment of trichotillomania, and medications used have not been consistently effective. Selective serotonin reuptake inhibitors have been utilized but responses to treatment have not been consistent. Fortunately, several recent studies regarding drug therapy for trichotillomania show promise. While drug therapy alone is currently generally not effective, combination therapy and other treatments may be helpful.

<s>[INST] What is (are) Costello syndrome ? [/INST] Costello syndrome is a rare condition that affects many different parts of the body. Signs and symptoms generally include developmental delay, intellectual disability, distinctive facial features, loose folds of extra skin (especially on the hands and feet), and unusually flexible joints. Affected people may also have heart abnormalities such as tachycardia, structural heart defects, and hypertrophic cardiomyopathy. Beginning in early childhood, people with Costello syndrome are at an increased risk of developing certain cancerous and noncancerous tumors. Costello syndrome is caused by changes (mutations) in the HRAS gene. It is considered an autosomal dominant condition; however, almost all reported cases are the result of de novo gene mutations and occur in people with no family history of the condition. Treatment is based on the signs and symptoms present in each person. </s></s>

<s>[INST] What is (are) Dopa-responsive dystonia ? [/INST] Dopa-responsive dystonia (DRD) is an inherited type of dystonia that typically begins during childhood but may begin in adolescence or adulthood. Depending on the specific type of DRD, specific symptoms can vary. Features can range from mild to severe. In most cases, dystonia begins in the lower limbs and spreads to the upper limbs over time. Symptoms may include unusual limb positioning; a lack of coordination when walking or running; sleep problems; and episodes of depression. Affected people also often develop a group of movement abnormalities called parkinsonism. Although movement difficulties usually worsen with age, they often stabilize around age 30. DRD may be caused by mutations in the GCH1, TH or SPR genes, or the cause may be unknown. Depending on the genetic cause, DRD may be inherited in an autosomal dominant (most commonly) or autosomal recessive manner. This form of dystonia is called 'dopa-responsive' dystonia because the symptoms typically improve during treatment with levodopa and carbidopa. </s></s>

<s>[INST] What are the symptoms of Dopa-responsive dystonia ? [/INST] What are the signs and symptoms of Dopa-responsive dystonia? The most common form of dopa-responsive dystonia (DRD) is autosomal dominant DRD (caused by a mutation in the GCH1 gene). This form of DRD is usually characterized by childhood-onset dystonia that may be associated with parkinsonism at an older age. The average age of onset is 6 years, and females are 2-4 times more likely than males to be affected. Symptoms usually begin with lower limb dystonia, resulting in gait problems that can cause stumbling and falling. Symptoms are often worse later in the day, a phenomenon known as diurnal fluctuation. In rare cases, the first symptom may be arm dystonia, tremor of the hands, slowness of movements, or cervical dystonia. This form of DRD usually progresses to affect the whole body, and some people also develop parkinsonism. Depression, anxiety, sleep disturbances and obsessive-compulsive disorder have been reported in some people. Intellectual function is normal. Those with onset at older ages tend to be more mildly affected. Another form of DRD is due to a rare condition called sepiapterin reductase deficiency, which is inherited in an autosomal recessive manner. This form of DRD is also characterized by dystonia with diurnal fluctuations, but also affects motor and cognitive development. Onset usually occurs before the first year of life. Sleep disturbances and psychological symptoms (anxiety, irritability) are common later in childhood. A third form of DRD is autosomal recessive DRD, also called tyrosine hydroxylase deficiency. This form is characterized by a spectrum of symptoms, ranging from those seen in the autosomal dominant form to progressive infantile encephalopathy. Onset is usually in infancy. Intellectual disability, developmental motor delay, and various other features may be present.

<s>[INST] Is Dopa-responsive dystonia inherited ? [/INST] How is dopa-responsive dystonia inherited? Depending on the genetic cause of dopa-responsive dystonia (DRD), it may be inherited in an autosomal dominant or autosomal recessive manner. When DRD is caused by mutations in the GCH1 gene, it is inherited in an autosomal dominant manner. This means that having a mutation in only one of the 2 copies of the gene is enough to cause signs and symptoms of the disorder. In some cases, an affected person inherits the mutation from an affected parent; other cases result from having a new (de novo) mutation in the gene. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit the mutated gene. Some people who inherit a mutated GCH1 gene never develop features of DRD; this phenomenon is known as reduced penetrance. When DRD is caused by mutations in the TH gene, it is inherited in an autosomal recessive manner. This means that a person must have mutations in both of their copies of the gene to be affected. The parents of a person with an autosomal recessive condition usually each carry one copy of the mutated gene and are referred to as carriers. Carriers typically do not have signs or symptoms. When parents who are both carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to be affected, a 50% chance to be an unaffected carrier like each parent, and a 25% chance to be unaffected and not be a carrier. When DRD is caused by mutations in the SPR gene, it can be inherited in an autosomal recessive or autosomal dominant manner. </s></s>

<s>[INST] How to diagnose Dopa-responsive dystonia ? [/INST] How is dopa-responsive dystonia diagnosed? Dopa-responsive dystonia (DRD) is diagnosed based on the signs and symptoms present, results of laboratory tests (sometimes including genetic testing), and response to therapy with levodopa. If DRD is suspected, a therapeutic trial with low doses of levodopa remains the most practical approach to the diagnosis. It is generally agreed that people with childhood-onset dystonia of unknown cause should be treated initially with levodopa. The characteristic symptoms and response to treatment are sufficient to establish the diagnosis for people with the most common form, autosomal dominant DRD. There is only one gene in which mutations are known to cause this form of DRD, but not all people with the disorder are found to have a mutation in the responsible gene. While finding a mutation may provide information about prognosis, it does not alter the treatment. Other types of laboratory tests, such as measuring specific substances or enzymes in the blood or cerebrospinal fluid (CSF), may be useful to support the diagnosis. For tyrosine hydroxylase deficiency, an autosomal recessive genetic cause of DRD, molecular genetic testing has confirmed the presence of mutations in all affected people to date. Specific laboratory tests performed on CSF help support the diagnosis but are not diagnostic on their own. For sepiapterin reductase deficiency, a very rare autosomal recessive form of DRD, there are distinctive findings in CSF and reduced or absent activity of sepiapterin reductase in fibroblasts. Molecular genetic testing can identify mutations in the responsible gene and confirm the diagnosis of this form of DRD. The major conditions that may have a similar presentation to DRD and are part of the differential diagnosis include early-onset parkinsonism, early-onset primary dystonia, and cerebral palsy or spastic paraplegia. People with specific questions about being evaluated for any form of dystonia should speak with a neurologist or other health care provider. </s></s>

<s>[INST] What is (are) Familial hypertrophic cardiomyopathy ? [/INST] Familial hypertrophic cardiomyopathy (HCM) is an inherited heart condition characterized by thickening of the heart muscle. The thickening most often occurs in the muscle wall that separates the left and right ventricles from each other (interventricular septum). This may restrict the flow of oxygen-rich blood from the heart, or it may lead to less efficient pumping of blood. Signs and symptoms can vary. While some people have no symptoms, others may have chest pain, shortness of breath, palpitations, lightheadedness, dizziness, and/or fainting. Even in the absence of symptoms, familial HCM can have serious consequences such as life-threatening arrhythmias, heart failure, and an increased risk of sudden death. Familial HCM may be caused by mutations in any of several genes and is typically inherited in an autosomal dominant manner. Treatment may depend on severity of symptoms and may include medications, surgical procedures, and/or an implantable cardioverter-defibrillator (ICD). </s></s>

<s>[INST] What causes Familial hypertrophic cardiomyopathy ? [/INST] What causes familial hypertrophic cardiomyopathy? Familial hypertrophic cardiomyopathy (HCM) is caused by mutations in any of several genes. The genes most commonly responsible are the MYH7, MYBPC3, TNNT2, and TNNI3 genes. Other genes that have not yet been identified may also be responsible for familial HCM. The genes known to be responsible for familial HCM give the body instructions to make proteins that play important roles in contraction of the heart muscle. The proteins form structures in muscle cells called sarcomeres, which are needed for muscle contractions. Sarcomeres are made of protein fibers that attach to each other and release, allowing muscles to contract. The contractions of heart muscle are needed to pump blood to the rest of the body. While it is unclear exactly how mutations in these genes cause familial HCM, they are thought to lead to abnormal structure or function of sarcomeres, or reduce the amount of proteins made. When the function of sarcomeres is impaired, normal heart muscle contractions are disrupted. </s></s>

<s>[INST] Is Familial hypertrophic cardiomyopathy inherited ? [/INST] How is familial hypertrophic cardiomyopathy inherited? Familial hypertrophic cardiomyopathy (HCM) is inherited in an autosomal dominant manner.

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 rare cases, a person with familial HCM has a mutation in both copies of the responsible gene, which leads to more severe signs and symptoms. </s></s>

<s>[INST] How to diagnose Familial hypertrophic cardiomyopathy ? [/INST] Is genetic testing available for familial hypertrophic cardiomyopathy? Yes. Familial hypertrophic cardiomyopathy (HCM) is caused by mutations in any of several known genes, and possibly other genes that have not yet been identified. Genetic testing for HCM is most informative as a "family test" rather than a test of one person. Results are most accurately interpreted after merging both genetic and medical test results from multiple family members. Ideally, the family member first having genetic testing should have a definitive diagnosis of HCM and be the most severely affected person in the family. Genetic testing of at-risk, asymptomatic relatives is possible when the responsible mutation has been identified in an affected family member. Testing should be performed in the context of formal genetic counseling. An algorithm showing a general approach to finding the specific genetic cause in people with HCM can be viewed here. The Genetic Testing Registry (GTR) provides information about the genetic tests for familial HCM. 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. As is often the case with genetic testing in general, there are benefits and limitations of genetic testing for familial HCM. Testing may confirm the diagnosis in a person with symptoms, and may help to identify family members at risk. However, results are sometimes unclear; testing cannot detect all mutations; and results cannot be used to predict whether a person will develop symptoms, age of onset, or long-term outlook (prognosis). </s></s>

<s>[INST] How to diagnose Narcolepsy ? [/INST] How is narcolepsy diagnosed? Narcolepsy is often diagnosed in adolescence and young adulthood, when falling asleep suddenly in school brings the problem to attention. However, for many people with narcolepsy, the disorder is not diagnosed for up to 10-15 years after symptoms first begin. The disorder may be misdiagnosed as various other conditions or psychological problems. While it is most easily recognized if all the major symptoms are reported, making the diagnosis based solely on symptoms is difficult. People often seek medical help for single symptoms that could be associated with other disorders, particularly epilepsy. In come cases, symptoms are not dramatically apparent for years. Sleep studies are an essential part of the evaluation of people with possible narcolepsy. The combination of an overnight polysomnogram (PSG) followed by a multiple sleep latency test (MSLT) can provide strongly suggestive evidence of narcolepsy, while excluding other sleep disorders. Measurement of hypocretin levels in the cerebrospinal fluid (CSF) may further help to establish the diagnosis. People with narcolepsy often have extremely low levels of hypocretin in their CSF. In some cases, human leukocyte antigen (HLA) typing may be helpful. </s></s>

<s>[INST] What are the treatments for Narcolepsy ? [/INST] How might narcolepsy be treated? There is currently no cure for narcolepsy, but some of the symptoms can be managed with medications and lifestyle changes. Most affected people improve if they maintain a regular sleep schedule, usually 7.5 to 8 hours of sleep per night. Scheduled naps during the day also may help. Other measures that may help include participating in an exercise program; receiving emotional support and career or vocational counseling; and avoiding high-risk behaviors such as alcohol and drug use, which may make symptoms worse. Common-sense measures should be taken to enhance sleep quality (such as avoiding heavy meals before bed time). Treatment with medications involves the use of central nervous system (CNS) stimulants. These medications help reduce daytime sleepiness and improve this symptom in 65-85% of affected people. Two types of antidepressant drugs (tricyclics, and selective serotonin and noradrenergic reuptake inhibitors) are effective in controlling cataplexy in many people. Sodium oxybate (a strong sedative taken during the night) may also be used to treat narcolepsy. You can view detailed information about the treatment of narcolepsy on Medscape's Web site. </s></s>

Other symptoms may include accumulation of fluid in the scrotum in males (hydrocele), upslanting toenails, deep creases in the toes, wart-like growths, prominent leg veins, and/or cellulitis. Milroy disease is sometimes caused by changes (mutations) in the FLT4 gene and is inherited in an autosomal dominant manner. In many cases, the cause remains unknown. Treatment may include lymphedema therapy to improve function and alleviate symptoms. </s></s>

<s>[INST] What are the symptoms of Milroy disease ? [/INST] What are the signs and symptoms of Milroy disease? The most common symptom of Milroy disease is build-up of fluids (lymphedema) in the lower limbs, which is usually present from birth or before birth. However, the degree and distribution of swelling varies among affected people. It sometimes progresses, but may improve in some cases. Other signs and symptoms may include hydrocele and/or urethral abnormalities in males; prominent veins; upslanting toenails; papillomatosis (development of wart-like growths); and cellulitis. Cellulitis may cause additional swelling. The Human Phenotype Ontology provides the following list of signs and symptoms for Milroy disease. 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.

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>

<s>[INST] Is Milroy disease inherited ? [/INST] How is Milroy disease inherited? Milroy disease is inherited in an autosomal dominant manner. This means that having one changed (mutated) copy of the responsible gene in each cell is enough to cause 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 people with Milroy disease have an affected parent, but some cases are due to new mutations that occur for the first time in the affected person. About 10-15% of people with a mutation in the responsible gene do not develop features of the condition. This phenomenon is called reduced penetrance. </s></s>

<s>[INST] How to diagnose Milroy disease ? [/INST] Is genetic testing available for Milroy disease? Yes. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for Milroy disease. The intended audience for the GTR is health care providers and researchers. People with questions about genetic testing should speak with a health care provider or genetics professional. If a mutation in the responsible gene has been identified in a family, genetic testing for at-risk relatives may identify those who may benefit from treatment early in the disease course. Prenatal testing for pregnancies at increased risk may also be available. </s></s>

<s>[INST] What are the treatments for Milroy disease ? [/INST] How might Milroy disease be treated? There is currently no cure for Milroy disease. Management is typically conservative and usually successful in most people. Management of lymphedema should be guided by a lymphedema therapist. Some improvement is usually possible with the use of properly fitted compression hosiery or bandaging and well fitting, supportive shoes. Good skin care is essential. These measures may improve the cosmetic appearance of the affected areas, decrease their size, and reduce the risk of complications. Decongestive physiotherapy, which combines compression bandaging, manual lymphatic drainage (a specialized massage technique), exercise, breathing exercises, dietary measures and skin care, has become the standard of care for primary lymphedema. People with recurrent cellulitis may benefit from prophylactic antibiotics. Surgical intervention is considered a last option when other medical management fails. When possible, people with Milroy disease should avoid: wounds to swollen areas (because of their reduced resistance to infection) long periods of immobility prolonged standing elevation of the affected limb certain medications (particularly calcium channel-blocking drugs that can cause increased leg swelling in some people) </s></s>

<s>[INST] What is (are) Orofaciodigital syndrome 2 ? [/INST] Orofaciodigital syndrome (OFDS) type 2 is a genetic condition that was first described in 1941 by Mohr. OFDS type 2 belongs to a group of disorders called orofaciodigital syndromes (OFDS) characterized by mouth malformations, unique facial findings, and abnormalities of the fingers and/or toes. Other organs might be affected in OFDS, defining the specific types. OFDS type 2 is very similar to oral-facial-digital syndrome (OFDS) type 1. However, the following are not found in OFDS type 1: (1) absence of hair and skin abnormalities; (2) presence of more than one fused big toe on each foot; (3) involvement of the central nervous system; and (4) heart malformations. Although it is known that OFDS type 2 is genetic, the exact gene that causes the syndrome has not been identified. The condition is believed to be inherited in an autosomal recessive pattern. Treatment is based on the symptoms present in the patient. </s></s>

<s>[INST] What causes Agenesis of the dorsal pancreas ? [/INST] What causes agenesis of the dorsal pancreas? Partial or complete agenesis of the dorsal pancreas results from the failure of the dorsal pancreatic bud to form the body and tail of the pancreas in the developing fetus. It may occur from the absence, or regression of, the dorsal bud during fetal development. Heredity may play a role in the development of this condition, but further research is needed to clarify this. There have been reports in the literature of the condition being associated (rarely) with other congenital diseases, specifically a very rare disorder called polysplenia/heterotaxy syndrome. In this case, it may occur due to errors in development of the asymmetric organs and may be associated with benign to severe congenital cardiac (heart) malformations. </s></s>

<s>[INST] What are the treatments for Agenesis of the dorsal pancreas ? [/INST] How might agenesis of the dorsal pancreas be treated? 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. </s></s>

<s>[INST] What are the symptoms of Brody myopathy ? [/INST] What are the signs and symptoms of Brody myopathy? Symptoms of Brody disease typically begin in childhood. Children with this condition may have a hard time keeping up with their peers in physical activities. They have a difficult time relaxing muscles, first in their arms and legs, but then in their face and trunk. They may also have difficulty relaxing their eyelids and grip. These muscle symptoms worsen with exercise and exposure to cold weather. In people with Brody disease, the term pseudomyotonia is used to describe these muscle symptoms. The term myotonia refers to muscle stiffness or an inability to relax the muscles and can be evidenced by abnormal electromyography (EMG) results. In Brody disease the EMG results are normal, even though the person show signs of the muscle stiffness. Because of the normal EMG results, the word pseudo-myotonia is used. In addition to the pseudomyotonia, people with Brody disease sometimes develop myoglobinuria. Myoglobinuria is the abnormal breakdown of the muscle protein, myoglobin. Click here to learn more about testing for myoglobinuria. People with Brody disease do not tend to have percussion myotonia.

<s>[INST] What causes Brody myopathy ? [/INST] What causes Brody disease? Brody disease can be caused by mutations in the gene ATP2A1. In general, genes contain the information needed to make functional molecules called proteins. These proteins are required for our bodies cells (and ultimately tissues, like our muscles) to work correctly. Gene mutations can result in faulty proteins. The ATP2A1 gene tells the body how to make a protein called SERCA Ca(2+)-ATPase. This protein is involved in moving calcium around in the cell, which is important for normal muscle contraction. Mutations in this gene results in problems with calcium transportation in the cell, and ultimately problems with muscle contraction. Not all people with Brody disease have mutations in the ATP2A1 gene. There are likely other gene mutations, that have not yet been identified, that can cause this disease. </s></s>
