<s>[INST] What is (are) Proud syndrome ? [/INST] Proud syndrome is a rare neurological condition that is primarily characterized by severe intellectual disability, agenesis of the corpus callosum, seizures, and spasticity. It usually occurs in males; when it occurs in females, the signs and symptoms are often less severe. Proud syndrome is caused by changes (mutations) in the ARX gene and is inherited in an X-linked recessive manner. Treatment is based on the signs and symptoms present in each person. </s>

<s>[INST] What are the symptoms of Proud syndrome ? [/INST] What are the signs and symptoms of Proud syndrome? The most common signs and symptoms of Proud syndrome are: Agenesis of the corpus callosum Severe intellectual disability Seizures Stiff and/or rigid muscles (spasticity) Other features may include microcephaly (unusually small head), limb contractures, scoliosis, characteristic facial features, kidney malformations, and genital abnormalities (i.e. cryptorchidism, hypospadias). Proud syndrome usually occurs in males; when it occurs in females, the signs and symptoms are often less severe. The Human Phenotype Ontology provides the following list of signs and symptoms for Proud 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.

<s>[INST] What causes Proud syndrome ? [/INST] What causes Proud syndrome? Proud syndrome is caused by changes (mutations) in the ARX gene, which encodes a protein that regulates the activity of other genes. This protein is especially important during early embryonic development since it is thought to be involved in the formation of many different body structures such as the pancreas, testes, brain, and muscles used for movement (skeletal muscles). For example, the protein helps regulate the process by which cells mature to carry out specific functions (differentiation) within the pancreas, testes, and muscles. In the developing brain, it plays many different roles such as assisting with the movement of neurons to their final locations. Specific changes in the ARX gene impair the function of the protein, which may disrupt the normal development of many different parts of the body. This can lead to the many signs and symptoms associated with Proud syndrome. </s>

<s>[INST] Is Proud syndrome inherited ? [/INST] How is Proud syndrome inherited? Proud syndrome is inherited in an X-linked recessive manner. A condition is considered X-linked if the mutated gene that causes the condition is located on the X chromosome, one of the two sex chromosomes (the Y chromosome is the other sex chromosome). Women have two X chromosomes and men have an X and a Y chromosome. In X-linked recessive conditions, men develop the condition if they inherit one gene mutation (they have only one X chromosome). Females are generally only affected if they have two gene mutations (they have two X chromosomes), although some females may rarely have a mild form of the condition if they only inherit one mutation. A woman with an X-linked recessive condition will pass the mutation on to all of her sons and daughters. This means that all of her sons will have the condition and all of her daughters will be carriers. A man with an X-linked recessive condition will pass the mutation to all of his daughters (carriers) and none of his sons. </s>

<s>[INST] What are the treatments for Proud syndrome ? [/INST] How might Proud syndrome be treated? The treatment of Proud syndrome is based on the signs and symptoms present in each person. For example, spasticity may be treated with a variety of therapies including medications and/or physical therapy. Medications may be prescribed to help prevent and/or control recurrent seizures. Surgery may be required to treat certain physical abnormalities such as kidney or genital issues. Children with severe intellectual disability may benefit from special education services. For personalized information about the treatment and management of Partington syndrome, please speak to a healthcare provider. </s>

<s>[INST] What is (are) Congenital anosmia ? [/INST] Congenital anosmia is a very rare condition in which people are born with a lifelong inability to smell. It may occur as an isolated abnormality (no additional symptoms) or be associated with a specific genetic disorder (such as Kallmann syndrome and congenital insensitivity to pain). Scientists suspect that isolated congenital anosmia occurs due to abnormal development of the olfactory system (the sensory system used for sense of smell) prior to birth. This may include abnormalities of the nasal cavity, disruptions in the pathway that carries information from the nose to the brain, and/or malformations of the portion of the brain that processes sense of smell. Unfortunately, there is currently no known cure or treatment for congenital anosmia. </s>

<s>[INST] What causes Congenital anosmia ? [/INST] What causes congenital anosmia? Congenital anosmia may occur as an isolated abnormality or be associated with specific genetic disorders (such as Kallmann syndrome and congenital insensitivity to pain). Most cases of isolated congenital anosmia (not associated with additional symptoms) occur sporadically in people with no family history of the condition. In these people, the exact underlying cause of the condition is unknown. Most likely, there is more than one cause. Scientists suspect that the condition occurs due to abnormal development of the olfactory system (the sensory system used for sense of smell) prior to birth. This may include abnormalities of the nasal cavity, disruptions in the pathway that carries information from the nose to the brain, and/or malformations of the portion of the brain that processes sense of smell. Rarely, isolated congenital anosmia can affect more than one family member. This suggests that there may be a genetic component in some cases. One study found that some people affected by isolated congenital anosmia have changes (mutations) in PROKR2 or PROK2, two genes that have previously been reported in people with Kallmann syndrome (an inherited condition associated with congenital anosmia and other symptoms). To date, no other disease-causing genes have been identified. </s>

<s>[INST] Is Congenital anosmia inherited ? [/INST] Is congenital anosmia inherited? Most cases of isolated congenital anosmia (not associated with additional symptoms) occur sporadically in people with no family history of the condition. Rarely, more than one family member may be affected. In these families, the condition appears to be inherited in an autosomal dominant manner with reduced penetrance. Congenital anosmia can also by associated with specific genetic disorders such as Kallmann syndrome and congenital insensitivity to pain. In these cases, the inheritance varies based on the associated condition. For example, Kallmann syndrome can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive manner depending on the underlying genetic cause (it can be caused by mutations in several different genes). Congenital insensitivity to pain follows an autosomal recessive pattern of inheritance. </s>

<s>[INST] How to diagnose Congenital anosmia ? [/INST] How is congenital anosmia diagnosed? Isolated congenital anosmia (not associated with other symptoms) is a diagnosis of exclusion. This means that the diagnosis is made in people with suspicious signs and symptoms once other conditions that cause similar features have been ruled out. When an affected person has no recollection of ever being able to smell, the following tests may be ordered to support a diagnosis of congenital anosmia: A thorough physical examination and medical history to look for other conditions that may interfere with the sense of smell Smell tests, particularly those that determine the smallest amount of odor that someone can detect Brain Imaging (such as CT scan and MRI scan) as some people with congenital anosmia have malformations in the portion of the brian that processes smells Nasal endoscopy to look for abnormalities of the nasal cavity which may interfere with sense of smell Olfactory nerve testing to evaluate disruptions in the pathway that carries information from the nose to the brain </s>

<s>[INST] What is (are) Alpha-1 antitrypsin deficiency ? [/INST] Alpha-1 antitrypsin deficiency (AATD) is a disorder that causes a deficiency or absence of the alpha-1 antitrypsin (AAT) protein in the blood. AAT is made in the liver and sent through the bloodstream to the lungs, to protect the lungs from damage. Having low levels of ATT (or no ATT) can allow the lungs to become damaged, making breathing hard. Age of onset and severity of AATD can vary based on how much ATT an affected person is missing. In adults, symptoms may include shortness of breath; reduced ability to exercise; wheezing; respiratory infections; fatigue; vision problems; and weight loss. Some people have chronic obstructive pulmonary disease (COPD) or asthma. Liver disease (cirrhosis) may occur in affected children or adults. Rarely, AATD can cause a skin condition called panniculitis. AATD is caused by mutations in the SERPINA1 gene and is inherited in a codominant manner. Treatment is based on each person's symptoms and may include bronchodilators; antibiotics for upper respiratory tract infections; intravenous therapy of AAT; and/or lung transplantation in severe cases. </s>

<s>[INST] What causes Alpha-1 antitrypsin deficiency ? [/INST] What causes alpha-1 antitrypsin deficiency? Alpha-1 antitrypsin deficiency (AATD) is caused by mutations in the SERPINA1 gene. This gene gives the body instructions to make a protein called alpha-1 antitrypsin (AAT), which protects the body from an enzyme called neutrophil elastase. Neutrophil elastase helps the body fight infections, but it can also attack healthy tissues (especially the lungs) if not controlled by AAT. Mutations that cause AAT can cause a deficiency or absence of AAT, or a form of AAT that does not work well. This allows neutrophil elastase to destroy lung tissue, causing lung disease. In addition, abnormal AAT can build up in the liver and cause damage to the liver. The severity of AATD may also be worsened by environmental factors such as exposure to tobacco smoke, dust, and chemicals. </s>

<s>[INST] How to diagnose Alpha-1 antitrypsin deficiency ? [/INST] How is alpha-1 antitrypsin deficiency diagnosed? Alpha-1 antitrypsin deficiency (AATD) may first be suspected in people with evidence of liver disease at any age, or lung disease (such as emphysema), especially when there is no obvious cause or it is diagnosed at a younger age. Confirming the diagnosis involves a blood test showing a low serum concentration of the alpha-1 antitrypsin (AAT) protein, and either: detecting a functionally deficient AAT protein variant by isoelectric focusing (a method for detecting mutations); or detecting SERPINA1 gene mutations on both copies of the gene with molecular genetic testing. (This confirms the diagnosis when the above-mentioned tests are not performed or their results are not in agreement.) Specialists involved in the diagnosis may include primary care doctors, pulmonologists (lung specialists), and/or hepatologists (liver specialists). </s>

<s>[INST] What are the treatments for Alpha-1 antitrypsin deficiency ? [/INST] How might alpha-1 antitrypsin deficiency be treated? Treatment of alpha-1 antitrypsin deficiency (AATD) depends on the symptoms and severity in each person. COPD and other related lung diseases are typically treated with standard therapy. Bronchodilators and inhaled steroids can help open the airways and make breathing easier. Intravenous augmentation therapy (regular infusion of purified, human AAT to increase AAT concentrations) has been recommended for people with established fixed airflow obstruction (determined by a specific lung function test). This therapy raises the level of the AAT protein in the blood and lungs. Lung transplantation may be an appropriate option for people with end-stage lung disease. Liver transplantation is the definitive treatment for advanced liver disease. When present, panniculitis may resolve on its own or after dapsone or doxycycline therapy. When this therapy does not help, it has responded to intravenous augmentation therapy in higher than usual doses. All people with severe AATD should have pulmonary function tests every 6 to 12 months. Those with ATT serum concentrations 10% to 20% of normal should have periodic evaluation of liver function to detect liver disease. People with established liver disease should have periodic ultrasounds of the liver to monitor for fibrotic changes and liver cancer (hepatocellular carcinoma). Yearly vaccinations against influenza and pneumococcus are recommended to lessen the progression of lung disease. Vaccination against hepatitis A and B is recommended to lessen the risk of liver disease. People with AATD should avoid smoking and occupations with exposure to environmental pollutants. Parents, older and younger siblings, and children of a person with severe AATD should be evaluated to identify as early as possible those who would benefit from treatment and preventive measures. </s>

<s>[INST] What is (are) Chronic intestinal pseudoobstruction ? [/INST] Chronic intestinal pseudo-obstruction (CIPO) is a rare but serious condition characterized by repetitive episodes or continuous symptoms of bowel obstruction when no blockage exists. The most common symptoms are abdominal swelling or bloating (distention), vomiting, abdominal pain, failure to thrive, diarrhea, constipation, feeding intolerance and urinary symptoms. CIPO can occur in people of any age. It may be primary or secondary. Problems with nerves, muscles, or interstitial cells of Cajal (the cells that set the pace of intestinal contractions) prevent normal contractions and cause problems with the movement of food, fluid, and air through the intestines. Primary or idiopathic (where the cause is unknown) CIPO occurs by itself. Secondary CIPO develops as a complication of another medical condition. Some people with primary CIPO have gain or loss of genetic material in the FLNA gene. The diagnosis of CIPO is clinical and other conditions with similar symptoms should be ruled out. Treatment may include nutritional support, medications, decompression or surgery. Management may require specialists from a variety of backgrounds. </s>

A clinical diagnosis of WS type 1 (the most common type) needs 2 major, or 1 major and 2 minor criteria. Major criteria: Congenital sensorineural hearing loss Iris pigmentary (coloration) abnormality, such as heterochromia iridis (complete, partial, or segmental); pale blue eyes (isohypochromia iridis); or pigmentary abnormalities of the fundus (part of the eye opposite the pupil) Abnormalities of hair pigmentation, such as white forelock (lock of hair above the forehead), or loss of hair color Dystopia canthorum lateral displacement of inner angles (canthi) of the eyes (in WS types 1 and 3 only) Having a 1st degree relative with Waardenburg syndrome Minor criteria: Congenital leukoderma (hypopigmented patches of skin) Synophrys (connected eyebrows or "unibrow") or medial eyebrow flare Broad or high nasal bridge (uppermost part of the nose) Hypoplasia of the nostrils Premature gray hair (under age 30) WS type 2 has similar features to WS type 1, but the inner canthi are normal (no dystopia cantorum present). WS type 3 also has similar features to WS type 1, but is additionally characterized by musculoskeletal abnormalities such as muscle hypoplasia (underdevelopment); flexion contractures (inability to straighten joints); or syndactyly (webbed or fused fingers or toes). WS type 4 has similar features to WS type 2, but with Hirschsprung disease (a condition resulting from missing nerve cells in the muscles of part or all of the large intestine). </s>

<s>[INST] What is (are) Marshall-Smith syndrome ? [/INST] Marshall-Smith syndrome is a malformation syndrome characterized by advanced bone age, failure to thrive, respiratory problems, dysmorphic facial features, and variable mental retardation. Less than 40 cases have been reported in the literature, mostly as single case reports or small series. Early death is common due to respiratory complications. The cause of this disease remains unknown, but its sporadic occurrence suggests a de novo (new) dominant mutation. Aggressive management of the early respiratory and feeding problems may improve survival in individuals affected by this condition. </s>

<s>[INST] What is (are) Histiocytosis-lymphadenopathy plus syndrome ? [/INST] Histiocytosis-lymphadenopathy plus syndrome is a group of conditions with overlapping signs and symptoms that affect many parts of the body. This group of disorders includes H syndrome, pigmented hypertrichosis with insulin-dependent diabetes mellitus (PHID), Faisalabad histiocytosis, and familial Rosai-Dorfman disease (also known as familial sinus histiocytosis with massive lymphadenopathy or FSHML). These conditions were once thought to be distinct disorders; however, because of the overlapping features and shared genetic cause, they are now considered to be part of the same disease spectrum. While some affected individuals have signs and symptoms characteristic of one of these conditions, others have a range of features from two or more of the conditions. The pattern of signs and symptoms can vary, even within the same family. All of the conditions in the spectrum are characterized by histiocytosis, which is an overgrowth of immune system cells called histiocytes. These cells abnormally accumulate in one or more tissues in the body, which can lead to organ or tissue damage. The lymph nodes are commonly affected, leading to swelling of the lymph nodes (lymphadenopathy). Other areas of cell accumulation can include skin, kidneys, brain and spinal cord (central nervous system), or digestive tract. The spectrum is known as histiocytosis-lymphadenoapthy plus syndrome because the disorders that make up the spectrum can have additional signs and symptoms. H syndrome is named for the collection of symptoms - all starting with the letter H - that are commonly present. These include hyperpigmented skin lesions with excessive hair growth (hypertrichosis) and histiocyte accumulation, enlargement of the liver or liver and spleen (hepatomegaly or hepatosplenomegaly), heart abnormalities, hearing loss, reduced amounts of hormones that direct sexual development (hypogonadism), and short stature (reduced height). In some cases, hyperglycemia/diabetes mellitus may also be present. PHID is characterized by patches of hyperpigmented skin with hypertrichosis and the development of type 1 diabetes during childhood. Faisalabad histiocytosis is characterized by lymphadenopathy and swelling of the eyelids due to the accumulation of histiocytes. Affected individuals may also have joint deformities (contractures) in their fingers or toes, and hearing loss. Familial Rosai-Dorfman disease is characterized by lymphadenopathy, most often in the neck. Histiocytes can also accumulate in other parts of the body. Histiocytosis-lymphadenopathy plus syndrome is caused by mutations in the SLC29A3 gene. The condition is inherited in an autosomal recessive pattern. Treatment is aimed at treating the symptoms present in each individual. </s>

Hiccups often develop for no apparent reason and typically go away on their own after a couple minutes. However, chronic hiccups last over two days and in rare cases, may continue for over a month. Hiccups that recur over long periods of time are also considered "chronic." Depending on how long the hiccups last, affected people may become exhausted, dehydrated and/or lose weight due to interruptions in sleep and normal eating patterns. Other complications may include irregular heart beat and gastroesophageal reflux. The exact underlying cause is often unknown; some cases may be caused by surgery, certain medications and/or a variety of health problems such as central nervous system (brain and spinal cord) abnormalities, psychological problems, conditions that irritate the diaphragm, and metabolic diseases.

Signs and symptoms may include joint pain in the hips and knees; early-onset arthritis; a waddling walk; and mild short stature as adults. Recessive MED may also cause malformations of the hands, feet, and knees; scoliosis; or other abnormalities. Most people are diagnosed during childhood, but mild cases may not be diagnosed until adulthood. Dominant MED is caused by mutations in the COMP, COL9A1, COL9A2, COL9A3, or MATN3 genes (or can be of unknown cause), and recessive MED is caused by mutations in the SLC26A2 gene. </s>

<s>[INST] Is Multiple epiphyseal dysplasia inherited ? [/INST] How is multiple epiphyseal dysplasia inherited? Multiple epiphyseal dysplasia (MED) may be inherited in an autosomal dominant or autosomal recessive manner depending on the genetic cause. Most cases are autosomal dominant. In autosomal dominant inheritance, having a mutation in only one of the 2 copies of the responsible gene is enough to cause the condition. The mutation may be inherited from a parent or can occur for the first time in the affected person. Each child of a person with an autosomal dominant condition has a 50% (1 in 2) chance to inherit the mutation. More rarely, MED is inherited in an autosomal recessive manner. In autosomal recessive inheritance, a person must have a mutation in both copies of the responsible gene to be affected. The parents of a person with an autosomal recessive condition usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not have signs or symptoms and are unaffected. When two carriers for the same condition have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% to be both unaffected and not a carrier. </s>

<s>[INST] What is (are) Split hand foot malformation ? [/INST] Split hand foot malformation (SHFM) is a type of birth defect that consists of missing digits (fingers and/or toes), a deep cleft down the center of the hand or foot, and fusion of remaining digits. The severity of this condition varies widely among affected individuals. SHFM is sometimes called ectrodactyly; however, this is a nonspecific term used to describe missing digits. SHFM may occur by itself (isolated) or it may be part of a syndrome with abnormalities in other parts of the body. At least six different forms of isolated SHFM have been described. Each type is associated with a different underlying genetic cause. SHFM1 has been linked to chromosome 7, and SHFM2 is linked to the X chromosome. SHFM3 is caused by a duplication of chromosome 10 at position 10q24. Changes (mutations) in the TP63 gene cause SHFM4. SHFM5 is linked to chromosome 2, and SHFM6 is caused by mutations in the WNT10B gene. SHFM may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. </s>

<s>[INST] What causes Split hand foot malformation ? [/INST] What causes split hand foot malformation? Split hand foot malformation may occur as an isolated feature or it may be associated with a genetic syndrome. Researchers believe that a large number of mutations can cause split hand foot malformation. A few of which have been identified: FBXW4 and TP63. Most commonly the conditions are passed through families in an autosomal dominant fashion with reduced penetrance. In autosomal dominant inheritance an affected parent would have a 1 in 2 or 50% chance with each pregnancy of passing the genetic defect to his/her offspring. In conditions with reduced penetrance a person who inherits the underlying genetic defect, may never develop the condition. More rarely other forms of inheritance have been reported (e.g., autosomal-recessive, X-linked, chromosome deletions, chromosome duplications). </s>

<s>[INST] What is (are) Congenital dyserythropoietic anemia type 2 ? [/INST] Congenital dyserythropoietic anemia type 2 (CDA II) is an inherited blood disorder characterized by mild to severe anemia. It is usually diagnosed in adolescence or early adulthood. Many affected individuals have yellowing of the skin and eyes (jaundice) and an enlarged liver and spleen (hepatosplenomegaly) and gallstones. This condition also causes the body to absorb too much iron, which builds up and can damage tissues and organs. In particular, iron overload can lead to an abnormal heart rhythm (arrhythmia), congestive heart failure, diabetes, and chronic liver disease (cirrhosis). Rarely, people with CDA type II have mediastinal tumors. CDA type II usually results from mutations in the SEC23B gene. It is inherited in an autosomal recessive pattern. Treatment depends on the severity of the symptoms and may involve blood transfusions, iron chelation therapy and removal of the spleen and gallbladder. </s>

<s>[INST] What are the treatments for Congenital dyserythropoietic anemia type 2 ? [/INST] How might congenital dyserythropoietic anemia (CDA) type 2 be treated? The goal of CDA type 2 treatment is to address and prevent complications from anemia and iron overload. Most people with CDA type 2 develop iron overload, for some this is as early as in their 20's. If a person with CDA type 2 has mild anemia, but evidence of iron loading, treatment may involve phlebotomy. An alternative treatment is chelation therapy. In particular, chelation therapy is preferred for people with iron (ferritin) levels greater than 1000 mg/L. The Iron Disorders Institute provides information on chelation therapy through their Web site at: http://www.irondisorders.org/chelation-therapy Many people with CDA-2 maintain hemoglobin levels just above the threshold for symptoms. Mild anemia may not need treatment, as long as it doesn't worsen. Less commonly CDA-2 causes severe anemia. Treatment of severe anemia may involve blood transfusions. Blood transfusions can raise iron levels so, careful monitoring and treatment for iron overload is required. The National Heart, Lung, and Blood Institute offers tips for living with hemolytic anemia at the following link: http://www.nhlbi.nih.gov/health/health-topics/topics/ha/livingwith Splenectomy is considered for people with CDA-2 and severe anemia. Splenectomy can cause a consistent rise in hemoglobin values. The spleen, however, is important in fighting infection. People, particularly children, who have had a splenectomy are more likely to contract a serious and possibly life-threatening infection (sepsis). This risk must be carefully weighed. Splenectomy does not affect iron overload. Lastly, people with very severe CDA-2 may be candidates for hematopoietic stem cell transplantation (HSCT). Currently this is the only available curative treatment for CDA-2. </s>

Congenital contractural arachnodactyly represents a broad spectrum of characteristics. The features are quite variable, both within and between families. The classic form is characterized by a Marfan-like appearance (tall and slender with arm span exceeding height), arachnodactyly (long slender fingers and toes), 'crumpled' ears, contractures of major joints from birth (particularly knees, elbows, fingers, toes, and hips), bowed long bones, muscular hypoplasia (underdeveloped muscles), kyphosis/scoliosis, aortic root dilation, and various craniofacial abnormalities (such as micrognathia, high arched palate, scaphocephaly (premature fusion of the sagittal suture of the skull leading to a long, narrow head), brachycephaly (premature fusion of the coronal suture, leading to a short skull), and frontal bossing). At the most severe end of the spectrum is a rare type with very few reported cases.

<s>[INST] What causes Congenital contractural arachnodactyly ? [/INST] What causes congenital contractural arachnodactyly? Congenital contractural arachnodactyly is caused by mutations in the FBN2 gene. The FBN2 gene provides instructions for producing the fibrillin-2 protein. Fibrillin-2 binds to other proteins and molecules to form threadlike filaments called microfibrils. Microfibrils become part of the fibers that provide strength and flexibility to connective tissue. Additionally, microfibrils hold molecules called growth factors and release them at the appropriate time to control the growth and repair of tissues and organs throughout the body. A mutation in the FBN2 gene can reduce the amount and/or quality of fibrillin-2 that is available to form microfibrils. As a result, decreased microfibril formation weakens the elastic fibers and allows growth factors to be released inappropriately, causing tall stature, deformities of the fingers and toes, and other characteristic features of congenital contractural arachnodactyly. </s>

<s>[INST] Is Congenital contractural arachnodactyly inherited ? [/INST] How is congenital contractural arachnodactyly inherited? This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.

<s>[INST] What are the treatments for Congenital contractural arachnodactyly ? [/INST] How might congenital contractural arachnodactyly be treated? Physical therapy for joint contractures helps increase joint mobility and ameliorate the effects of muscle hypoplasia (usually in the calf muscles). In severe cases, surgical release may be necessary. Since the kyphosis/scoliosis tends to be progressive, bracing and/or surgical correction is often needed. Consultation with an orthopedist is encouraged. Other symptoms, if present, should be addressed as they arise and in the standard manner. Regular physician visits should be scheduled to monitor symptom progression and development. </s>

<s>[INST] What is (are) Kuskokwim disease ? [/INST] Kuskokwim disease is a congenital (present at birth) contracture disorder that occurs solely among Yup'ik Eskimos in and around the Kuskokwim River delta region of southwest Alaska. Affected individuals usually, but not always, have congenital contractures of large joints (especially knees and/or elbows) and spinal, pelvic, and foot deformities. Other skeletal features have also been reported. Kuskokwim disease has been shown to be caused by mutations in the FKBP10 gene and is inherited in an autosomal recessive manner. </s>

<s>[INST] What are the symptoms of Kuskokwim disease ? [/INST] What are the signs and symptoms of Kuskokwim disease? The range and and severity of signs and symptoms in individuals with Kuskokwim disease can vary, even among siblings. Affected individuals usually have congenital contractures, especially of lower extremities, which progress during childhood and persist for the lifetime of the individual. However, not all individuals with the condition have contractures at birth. The severity of contractures can be very asymmetrical in any given individual. The knees and elbows are often affected, and skeletal abnormalities of the spine, pelvis, and feet also commonly occur. Muscle atrophy of limbs with contractures and displacement of kneecaps (patellae) have also been reported. Milder skeletal features are common. Vertebral features may include spondylolisthesis, mild to moderate scoliosis, and/or lordosis. Many affected individuals have had several low-energy fractures. Other skeletal abnormalities that have been reported include bunions (hallux valgus), "flat feet" (plano valgus feet), and clubfoot (talipes equinovarus). Development and arrangement of the teeth (dentition) are normal. Although some individuals with full bilateral contractures of the knees can move about by duck walking (sitting with buttocks on their heels) or by knee walking (moving on their knees with their lower legs drawn up behind them to their buttocks), most affected individuals are treated with leg braces and/or surgery in childhood and can walk upright.

Many individuals with Kuskokwim disease are treated with leg braces and/or surgery and eventually are able to walk upright. </s>

<s>[INST] What is (are) Beta-thalassemia ? [/INST] Beta-thalassemia is a blood disorder that reduces the body's production of hemoglobin. Low levels of hemoglobin lead to a shortage of mature red blood cells and a lack of oxygen in the body. Affected people have anemia, which can cause paleness, weakness, fatigue, and more serious complications. Severe beta-thalassemia is called thalassemia major or Cooleys anemia. Thalassemia intermedia is a less severe form. Beta-thalassemia is caused by mutations in the HBB gene and is usually inherited in an autosomal recessive manner. People who have only one HBB gene mutation may have no symptoms or develop mild symptoms, and are said to have thalassemia minor. Treatment depends on the severity in each person and may include transfusions, folic acid supplementation, iron chelation, and/or bone marrow transplantation (the only definitive cure). </s>

<s>[INST] Is Beta-thalassemia inherited ? [/INST] How is beta-thalassemia inherited? Beta-thalassemia major and beta-thalassemia intermedia are usually inherited in an autosomal recessive manner, which means both copies of the HBB gene in each cell have mutations. The parents of a person with an autosomal recessive condition each carry one copy of the mutated gene and are referred to as carriers. When two carriers have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% (1 in 4) chance to be unaffected and not be a carrier. Sometimes, people with only one HBB gene mutation in each cell (carriers) do have mild anemia. These people are said to have 'beta-thalassemia minor' or 'beta-thalassemia trait.' In a small percentage of families, the condition is inherited in an autosomal dominant manner. In these cases, one mutated copy of the gene in each cell is enough to cause the signs and symptoms of beta-thalassemia. </s>

<s>[INST] What is (are) Logopenic progressive aphasia ? [/INST] Logopenic progressive aphasia (LPA) is a type of dementia characterized by language disturbance, including difficulty making or understanding speech (aphasia). It is a type of primary progressive aphasia (PPA). Affected individuals have slow, hesitant speech due to difficulty retrieving the correct words, names, or numbers. Difficulty with phase and sentence repetition are additionally present. Speech is typically well articulated and grammatically correct with good single-word comprehension. But over time, affected individuals may have trouble understanding long or complex verbal information, due to problems holding onto lengthy information that they hear. Language difficulties associated with LPA are due to shrinking, or atrophy, in the left posterior temporal cortex and inferior parietal lobule.

<s>[INST] What are the treatments for Logopenic progressive aphasia ? [/INST] How might logopenic progressive aphasia be treated? Although no medications or interventions have demonstrated long-term stabilization of logopenic progressive aphasia (LPA), different treatment methods have shown promising short-term benefits. Studies utilizing language therapy and behavioral interventions have shown encouraging results. Neuromodulation through methodologies such as Transcranial Direct Current Stimulation (tDCS) and transcranial magnetic stimulation (rTMS) have additionally been identified as a promising therapies to potentially use in combination with behavioral treatment and language therapy. As the most common underlying pathology of LPA is Alzheimer's disease (AD) pathology, limited research has been completed on interventions shown to reduce the rate of decline in cognitive symptoms in AD. So far cholinesterase inhibitors and memantine, medications used in Alzheimers disease, have not been proven effective in treating logopenic progressive aphasia. Case studies involving steriod use and Omentum Transposition Therapy have reported improvement; however, the results have not been replicated in other cases and as with other treatment options, long-term studies are lacking.

<s>[INST] What is (are) Myofibrillar myopathy ? [/INST] Myofibrillar myopathies (MFM) are a group of neuromuscular disorders characterized by slowly progressive weakness that can involve both proximal muscles (such as hips and shoulders) and distal muscles (those farther away from the trunk). Some affected individuals also experience sensory symptoms, muscle stiffness, aching, or cramps. Peripheral neuropathy or cardiomyopathy may also be present. Most people with MFM begin to develop muscle weakness in mid-adulthood, but features of the condition can appear anytime between infancy and late adulthood. It may be caused by mutations in any of several genes, including DES, CRYAB, MYOT, LDB3, FLNC, and BAG3; the signs and symptoms of MFM can vary widely depending on the condition's genetic cause. It is inherited in an autosomal dominant manner. Treatment may include a pacemaker and implantable cardioverter defibrillator (ICD) for arrhythmia or cardiac conduction defects; cardiac transplantation for progressive or life-threatening cardiomyopathy; respiratory support for respiratory failure; and physical therapy and assistive devices for those with advanced muscle weakness. </s>

<s>[INST] What are the symptoms of Myofibrillar myopathy ? [/INST] What are the signs and symptoms of Myofibrillar myopathy? Myofibrillar myopathy (MFM) primarily affects skeletal muscles, which are muscles that the body uses for movement. In some cases, the heart (cardiac) muscle is also affected. The signs and symptoms of MFM vary widely among affected individuals, typically depending on the condition's genetic cause. Most people with this disorder begin to develop muscle weakness (myopathy) in mid-adulthood. However, features of this condition can appear anytime between infancy and late adulthood. Muscle weakness most often begins in the hands and feet (distal muscles), but some people first experience weakness in the muscles near the center of the body (proximal muscles). Other affected individuals develop muscle weakness throughout their body. Facial muscle weakness can cause swallowing and speech difficulties. Muscle weakness worsens over time. Other signs and symptoms of MFM can include a weakened heart muscle (cardiomyopathy), muscle pain (myalgia), loss of sensation and weakness in the limbs (peripheral neuropathy), and respiratory failure. Individuals with this condition may have skeletal problems including joint stiffness (contractures) and abnormal side-to-side curvature of the spine (scoliosis).

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>
