<s>[INST] What is (are) Adult-onset vitelliform macular dystrophy ? [/INST] Adult-onset vitelliform macular dystrophy (AVMD) is an eye disorder that can cause progressive vision loss. AVMD affects an area of the retina called the macula, which is responsible for sharp central vision. The condition causes a fatty yellow pigment to accumulate in cells underlying the macula, eventually damaging the cells. Signs and symptoms usually begin between ages 30 and 50 and include blurred and/or distorted vision, which can progress to central vision loss over time.Historically, AVMD has been characterized as a genetic disorder caused by mutations in the PRPH2, BEST1, IMPG1, and IMPG2 genes; however, recent studies focused on genetic testing suggest that there may be other unidentified genes and/or environmental causes.The majority of cases due to a mutation in the identified genes are inherited in an autosomal dominant manner; however not all individuals have AVMD have a family history and not all individuals who inherit a causative gene mutation develop symptoms. </s>

<s>[INST] What are the symptoms of Adult-onset vitelliform macular dystrophy ? [/INST] What are the signs and symptoms of Adult-onset vitelliform macular dystrophy? Signs and symptoms of adult-onset vitelliform macular dystrophy typically begin during mid-adulthood, in the fourth or fifth decade of life. At the time of diagnosis, individuals may have minimal visual symptoms (such as mild blurring) or mild metamorphopsia (distorted vision). Cells underlying the macula become more damaged over time, which can cause slowly progressive vision loss. The condition is usually bilateral (affecting both eyes). It usually does not affect peripheral vision or the ability to see at night. Studies have revealed much variability in the signs, symptoms and progression of this condition. It has been reported that while one individual may not have significant changes in visual acuity over several years, another may experience ongoing visual loss. It has been suggested that in the majority of affected individuals, progression of functional loss is limited. In general, the long-term outlook (prognosis) is usually good, but loss of central visual function is possible. The Human Phenotype Ontology provides the following list of signs and symptoms for Adult-onset vitelliform macular dystrophy. 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>[INST] What causes Adult-onset vitelliform macular dystrophy ? [/INST] What causes adult-onset vitelliform dystrophy? Historically, adult-onset vitelliform macular dystrophy (AVMD) was defined as a genetic disorder; however, recent studies have concluded that only a minority of cases have an identified genetic cause, suggesting that there might be other underlying causes of environmental origin, genetic origin, or a mix of genetics and environment (multifactorial). More studies are needed to better define other underlying causes that might be present, whether of genetic or environmental origin. Currently known genetic causes include mutations in the PRPH2, BEST1, IMPG1, and IMPG2 genes. It is additionally suspected that AVMD might be associated with a single-nucleotide polymorphism (variant DNA sequence) in the HTRA1 gene. Single-nucleotide polymorphisms in the HTRA1 gene are additionally associated with age-related macular degeneration. </s>

<s>[INST] Is Adult-onset vitelliform macular dystrophy inherited ? [/INST] How is adult-onset vitelliform macular dystrophy inherited? The majority of cases with an identified family history or genetic cause are inherited in an autosomal dominant manner. This means that in order to be affected, a person only needs a change (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 a new (de novo) mutation in the gene. These cases occur in people with no history of the disorder in their family. When caused by a known mutation inherited in an autosomal dominant manner, a person with adult-onset macular dystrophy (AVMD) has a 50% chance with each pregnancy of passing along the altered gene to his or her child. The inheritance pattern of AVMD can be confusing as not all individuals with AVMD have a family history and not all individuals who inherit a causative gene mutation develop symptoms. </s>

<s>[INST] What are the treatments for Adult-onset vitelliform macular dystrophy ? [/INST] How might adult-onset vitelliform macular dystrophy be treated? Management for this condition should include a comprehensive eye examination, including dilation, once or twice a year to rule out any possible complications. If vision is impaired, patients should be referred for low vision testing and rehabilitation. Intravitreal injections of either Ranibizumab or Bevacizumab may be effective in the short-term. Transcorneal electrical stimulation has also been found to improve visual acuity in individuals with this condition. </s>

<s>[INST] What is (are) Familial amyloidosis, Finnish type ? [/INST] Familial amyloidosis, Finnish type, or gelsolin amyloidosis, is a condition characterized by abnormal deposits of amyloid protein that mainly affect the eyes, nerves and skin. The 3 main features are amyloid deposits in the cornea (corneal lattice dystrophy), bilateral facial paralysis, and cutis laxa ("sagging" skin). Symptoms generally worsen with age. This condition is inherited in an autosomal dominant manner and is caused by mutations in the GSN gene. Treatment generally focuses on specific signs and symptoms. Plastic surgery may relieve problems caused by facial paralysis and cutis laxa. </s>

<s>[INST] What are the symptoms of Familial amyloidosis, Finnish type ? [/INST] What are the signs and symptoms of Familial amyloidosis, Finnish type? Symptoms of this condition usually begin in an individual's 20s or 30s, and they usually emerge in a specific order. The progression is often slow, but varies among individuals. The typical triad of features includes accumulation of amyloid deposits in the cornea (lattice corneal dystrophy), cutis laxa (sagging skin), and nervous system symptoms (neuropathy). Eye symptoms typically begin first. The amyloid deposits cloud the cornea, often leading to vision impairment. Other eye symptoms may include dryness, irritation and light sensitivity. Affected individuals may eventually develop cataracts and glaucoma. As the condition progresses, the nerves become involved (typically in an individual's 40s). Dysfunction of the nerves in the head and face (cranial nerves) causes paralysis of facial muscles and decreased sensation, which can lead to difficulty speaking, chewing, and swallowing. Facial paralysis can also cause additional eye symptoms including ectropium (turning out of the eyelid), corneal ulcers, or droopy eyelids (ptosis). Affected individuals may also have peripheral neuropathy. Central nervous system symptoms such as impaired cognitive function are rare but have been reported in older individuals. Skin manifestations may also begin in a person's 40s and include a thickened, sagging appearance and cutis laxa (loose skin that lacks elasticity), especially on the face. Cutis laxa worsens with age. Other signs and symptoms that have been reported in some people include gastric motility changes, orodental problems, heart palpitations, cardiac conduction problems, and mild proteinuria.

<s>[INST] What is (are) Chromosome 8q deletion ? [/INST] Chromosome 8q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 8. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 8q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person. </s>

<s>[INST] What is (are) Hemoglobin E disease ? [/INST] Hemoglobin E (HbE) disease is an inherited blood disorder characterized by an abnormal form of hemoglobin, called hemoglobin E. People with this condition have red blood cells that are smaller than normal and have an irregular shape. HbE disease is thought to be a benign condition. It is inherited in an autosomal recessive pattern and is caused by a particular mutation in the HBB gene. The mutation that causes hemoglobin E disease has the highest frequency among people of Southeast Asian heritage (Cambodian, Laotian, Vietnamese and Thai). However, it is also found in people of Chinese, Filipino, Asiatic Indian, and Turkish descent. </s>

<s>[INST] What are the symptoms of Hemoglobin E disease ? [/INST] What are the signs and symptoms of hemoglobin E disease? Affected individuals can develop mild thalassemia in the first few months of life. While mild splenomegaly and/or anemia can occur, it is generally considered a benign condition. When a person inherits a gene mutation from one of their parents, they are said to be a carrier or have hemoglobin trait. These individuals are typically asymptomatic, although they may have small red blood cells. However, carriers may be at risk to have children with hemoglobin E/thalassemia (which is similar to thalassemia) or hemoglobin sickle E disease (milder form of sickle cell anemia). Both of these conditions are much more severe than hemoglobin E disease. They are are also inherited in an autosomal recessive fashion. </s>

<s>[INST] How to diagnose Hemoglobin E disease ? [/INST] How is hemoglobin E disease diagnosed? Many babies are picked up through state newborn screening programs. A diagnosis is usually made by looking at the red blood cells by doing a Mean Corpuscular Volume (MCV) test, which is commonly part of a Complete Blood Count (CBC) test. More specialized tests, such as a hemoglobin electrophoresis and iron studies might be done. These tests indicate whether a person has different types of hemoglobin. Genetic testing of the HBB gene can also be done to confirm a diagnosis. </s>

<s>[INST] What are the treatments for Hemoglobin E disease ? [/INST] How might hemoglobin E disease be treated? Treatment is usually not necessary. Folic acid supplements may be prescribed to help the body produce normal red blood cells and improve symptoms of anemia. People with hemoglobin E disease can expect to lead a normal life. </s>

<s>[INST] What is (are) Juvenile temporal arteritis ? [/INST] Juvenile temporal arteritis is a rare form of vasculitis, a group of conditions that cause inflammation of the blood vessels. Unlike the classic form of temporal arteritis, this condition is generally diagnosed in late childhood or early adulthood and only affects the temporal arteries (located at the lower sides of the skull, directly underneath the temple). Affected people often have no signs or symptoms aside from a painless nodule or lump in the temporal region. The exact underlying cause of the condition is unknown. It generally occurs sporadically in people with no family history of the condition. Juvenile temporal arteritis is often treated with surgical excision and rarely recurs. </s>

<s>[INST] What is (are) Ring chromosome 20 ? [/INST] Ring chromosome 20 is a chromosome abnormality that affects the development and function of the brain. People with ring chromosome 20 often have recurrent seizures or epilepsy. Other symptoms might include intellectual disability, behavioral difficulties, growth delay, short stature, a small head (microcephaly), and characteristic facial features. Ring chromosome 20 is caused by an abnormal chromosome known as a ring chromosome 20 or r(20). A ring chromosome is a circular structure that occurs when a chromosome breaks in two places and its broken ends fuse together. Ring chromosome 20 is usually not inherited. It almost always occurs by chance during the formation of reproductive cells (eggs or sperm) or in early embryonic development. Treatment for ring chromosome 20 is focused on management of seizures and accommodations for learning. </s>

<s>[INST] What are the treatments for Ring chromosome 20 ? [/INST] How might ring chromosome 20 be treated? Treatment of ring chromosome 20 is typically focused on management of seizures. The seizures associated with ring chromosome 20 do not generally respond well to medications. The treatment that is successful varies from person to person. Broad spectrum AEDs are usually tried first since they are active against different seizure types. This includes valproate, levetiracetam, lamotrigine, topiramate and zonisamide. Success has been reported in some people with a combination of valproate and lamotrigine, but so far no single therapy has worked for everyone. Vagus nerve stimulation (VNS) has been tried and a reduction in seizures has been reported in some cases but not in others. This involves implanting a medical device under the skin, similar to a pacemaker that delivers a mild electrical current to the brain via the vagus nerve. The long-term effectiveness of VNS therapy is not yet known. The ketogenic diet, which is high in fat and low in carbohydrate, has been shown to be helpful in other types of epilepsy. However there are no published reports about whether this is successful or not in ring chromosome 20 epilepsy.

Affected individuals have slow growth before birth followed by hyperglycemia, dehydration and failure to thrive in infancy. Approximately 70% of cases are caused by the overactivity of certain genes in a region of the long (q) arm of chromosome 6 called 6q24. These cases are referred to as 6q24-related TNDB; most (but not all) of these cases are not inherited. Other genetic causes include mutations in the KCNJ11 and ABCC8 genes, which usually cause permanent neonatal diabetes.

<s>[INST] What is (are) Schwartz Jampel syndrome type 1 ? [/INST] Schwartz Jampel syndrome type 1 (SJS1) is a genetic disorder that affects bone and muscle development. Signs and symptoms may include muscle weakness and stiffness, abnormal bone development, joint contractures, short stature, small, fixed facial features, and eye abnormalities (some of which may impair vision). SJS1 can be divided into two subtypes differentiated by severity and age of onset. Type 1A, considered classic SJS, is the most commonly recognized type. Individuals with type 1A typically develop more mild symptoms later in childhood, while individuals with type 1B have symptoms that are more severe and are apparent immediately after birth. SJS1 is caused by mutations in the HSPG2 gene which makes a protein called perlecan. SJS1 is thought to be inherited in an autosomal recessive manner; however, some cases reported in the medical literature suggest an autosomal dominant inheritance pattern. Treatment for both type 1A and 1B aims to normalize muscle activity through various methods including massage and stretching, medications such as Botulinum toxin, and surgery. There is a more severe, distinct condition called Stuve-Wiedemann syndrome which is caused by mutations in the LIFR gene. At one time cases of Stuve-Wiedemann syndrome were referred to as Neonatal Schwartz Jampel syndrome type 2. Click on the link above to learn more about this syndrome. </s>

Individuals with Schwartz-Jampel syndrome type 1 (SJS1) have characteristic facial features, muscle weakness (hypotonia), and muscle stiffness (myotonia). Facial features of individuals with SJS1 can seem "fixed" in the same expression with puckered lips due to weakening and stiffening of the facial muscles. Additional facial features may include: Blepharophimosis (narrowing of the eye opening) Epicanthal folds (skin fold of the upper eyelid covering the inner corner of the eye) Blepharospasm (involuntary blinking or spasm of the eyelids) Hypertrichosis (excessive hair) of the eye lashes Micrognathia (small lower jaw) Individuals with SJS1 usually have short stature. Other skeletal and joint findings may include: Shortened neck Pectus carinatum (outward bowing of the chest) Kyphosis (curving of the spine that causes a bowing or rounding of the back) Coxa valga (hip deformity involving an increased neck-shaft angle of the femur) Joint contractures Osteoporosis Widening of the metaphysis (portion of the bone containing the growth plate) Delayed bone age Other less common symptoms include: a high pitched voice, bilateral carpel tunnel syndrome, and malignant hyperthermia.

<s>[INST] What causes Schwartz Jampel syndrome type 1 ? [/INST] What causes Schwartz Jampel syndrome type 1? Schwartz Jampel syndrome type 1 (SJS1) is caused by mutations in the HSPG2 gene. The HSPG2 gene codes for the protein perlecan, which is found in muscle and cartilage. Although the role of the perlecan protein is not fully understood, it is thought to play an essential role in many biological activities such as cell signaling and cellular structure. In SJS1, it is suspected that a disturbance in perlecan function leads to a deficiency of acetylcholinesterase, an enzyme involved in breaking down acetylcholine, a neurotransmitter that sends messages between nerves, leading to muscle contraction. If acetylcholine is not broken down, it may lead to an prolonged muscle contraction or stiffening of the muscles (myotonia). </s>

<s>[INST] Is Schwartz Jampel syndrome type 1 inherited ? [/INST] How is Schwartz Jampel syndrome type 1 inherited? The majority of cases of Schwartz Jampel syndrome type 1 (SJS1) are inherited in an autosomal recessive pattern. This means that to have the disorder, a person must have a mutation in both copies of the responsible gene in each cell. Individuals with SJS1 inherit one mutated copy of the gene from each parent, who is referred to as a carrier. Carriers of an autosomal recessive condition typically do not have any signs or symptoms (they are unaffected). Rarely, cases of SJS1 with autosomal dominant inheritance have been reported. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition. </s>

<s>[INST] How to diagnose Schwartz Jampel syndrome type 1 ? [/INST] How is Schwartz Jampel syndrome type 1 diagnosed? The diagnosis of Schwartz Jampel syndrome type 1 (SJS1) is suspected based on clinical findings including characteristic facial features, skeletal features, and muscle stiffness (myotonia). Studies that may be useful in diagnosing SJS1 include: blood tests (which may show elevated serum creatine kinase or adolase); imaging studies; muscle biopsy; and electromyography (EMG)/nerve conduction studies. Genetic testing of the HSPG2 gene may additionally be helpful to confirm the diagnosis. </s>

<s>[INST] What are the treatments for Schwartz Jampel syndrome type 1 ? [/INST] How might Schwartz Jampel syndrome type 1 be treated? Treatment of Schwartz Jampel syndrome type 1 (SJS1) aims to reduce stiffness and cramping of muscles. This might include nonpharmacologic modalities such as massage, warming of muscles, and gradual strengthening exercises. Medications that might be utilized include muscle relaxants and anti seizure medications, particularly Carbamazepine. Botox might additionally be used to relieve eye symptoms such as blepharospasm (involuntary blinking of spasm of eyes).

<s>[INST] What is (are) Pachyonychia congenita ? [/INST] Pachyonychia congenita (PC) is a rare inherited condition that primarily affects the nails and skin. The fingernails and toenails may be thickened and abnormally shaped. Affected people can also develop painful calluses and blisters on the soles of their feet and less frequently on the palms of their hands (palmoplantar keratoderma). Additional features include white patches on the tongue and inside of the mouth (leukokeratosis); bumps around the elbows, knees, and waistline (follicular hyperkeratosis); and cysts of various types including steatocystoma. Features may vary among affected people depending on their specific mutation. PC is divided into 5 types based on the specific keratin gene involved: PC-K6a, PC-K6b, PC-K6c, PC-K16, and PC-K17. All forms are inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person. </s>

<s>[INST] What causes Pachyonychia congenita ? [/INST] What causes pachyonychia congenita? Pachyonychia congenita (PC) is caused by changes (mutations) in one of five genes: KRT6A, KRT6B, KRT6C, KRT16, and KRT17. These genes provide instructions for making a protein called keratin, which is found in the skin, hair, and nails. Mutations in any of these genes alter the structure of keratin proteins which interferes with their ability to provide strength and resilience to various parts of the body. This leads to the many signs and symptoms associated with pachyonychia congenita. PC is divided into 5 types based on the specific keratin gene involved: PC-K6a, PC-K6b, PC-K6c, PC-K16, and PC-K17. </s>

<s>[INST] Is Pachyonychia congenita inherited ? [/INST] How is pachyonychia congenita inherited? Pachyonychia congenita (PC) is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (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 PC has a 50% chance with each pregnancy of passing along the altered gene to his or her child. </s>

<s>[INST] How to diagnose Pachyonychia congenita ? [/INST] Is genetic testing available for pachyonychia congenita? Yes, genetic testing is available for the five genes known to cause pachyonychia congenita. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is pachyonychia congenita diagnosed? A diagnosis of pachyonychia congenita (PC) is often suspected based on the presence of characteristic signs and symptoms. In fact, one study found that approximately 97% of people with genetically confirmed PC have toenail thickening, plantar keratoderma (thickening of the skin on the soles of the feet) and plantar pain by age ten. Identification of a change (mutation) in one of the five genes associated with PC confirms the diagnosis. </s>

Hormones appear to play a role, especially considering that the condition occurs almost entirely in females and often develops after puberty or other periods of hormone change (e.g., pregnancy, menopause). Although people who are obese may be overrepresented among those with lipedema, persons of normal weight are also commonly affected. As a result, obesity alone is unlikely to be a major determinant of this syndrome. Many people with lipedema have a family history of similarly enlarged legs. At this time the role of genetics in the causation of lipedema is unknown. </s>

<s>[INST] What is (are) Factor V Leiden thrombophilia ? [/INST] Factor V Leiden thrombophilia is an inherited disorder that results in an increased risk of developing abnormal blood clots. Factor V Leiden is the name of a specific gene mutation in the F5 gene. This gene plays a critical role in the normal formation of blood clots in response to an injury. People can inherit one or two copies of the factor V Leiden gene mutation. Those who inherit one copy are called heterozygotes. People who inherit two copies of the mutation, one from each parent, are called homozygotes. Having the factor V Leiden mutation increases your risk for developing a clot in your legs called a deep venous thrombosis (DVT). It also increases your risk of developing a clot that travels through the bloodstream and lodges in the lungs, called a pulmonary embolism (PE). </s>

<s>[INST] What are the symptoms of Factor V Leiden thrombophilia ? [/INST] What are the signs and symptoms of factor V Leiden thrombophilia? Individuals affected by factor V Leiden thrombophilia have an increased risk of developing blood clots. The severity of factor V Leiden thrombophilia is extremely variable. Many individuals with the factor V Leiden allele never develop a blood clot. Although most individuals with factor V thrombophilia do not experience their first thrombotic event until adulthood, some have recurrent thromboembolism before age 30 years. The chance a person will develop a blood clot is affected by the number of factor V Leiden mutations, the presence of coexisting genetic abnormalities, and non-genetic risk factors. Non-genetic risk factors include surgery, long periods of not moving (like sitting on a long airplane ride), birth control pills and other female hormones, childbirth within the last 6 months, and traumas or fractures. Individuals who inherit one copy of the factor V Leiden mutation have a fourfold to eightfold increase in the chance of developing a clot. Homozygotes (people who inherit two factor V Leiden mutations) may have up to 80 times the usual risk of developing a blood clot. Considering that the risk of developing an abnormal blood clot averages about 1 in 1,000 per year in the general population, the presence of one copy of the factor V Leiden mutation increases that risk to 4 to 8 in 1,000, and having two copies of the mutation may raise the risk as high as 80 in 1,000. People with factor V Leiden have an increased chance of having a blood clot that forms in large veins in the legs (deep venous thrombosis, or DVT) or a clot that travels through the bloodstream and lodges in the lungs (pulmonary embolism, or PE). Symptoms of deep vein thrombosis usually include leg pain, tenderness, swelling, increased warmth or redness in one leg. The symptoms of pulmonary embolism usually include cough, chest pain, shortness of breath or rapid heartbeat or breathing. To learn more about the symptoms of DVT and PE, click here. </s>

<s>[INST] What causes Factor V Leiden thrombophilia ? [/INST] What causes factor V Leiden thrombophilia? Factor V Leiden thrombophilia is caused by a specific mutation in the Factor V gene. Factor V plays a critical role in the formation of blood clots in response to injury. Genes are our bodys instructions for making proteins. The factor V gene instructs the body how to make a protein called coagulation factor V. Coagulation factor V is involved in a series of chemical reactions that hold blood clots together. A molecule called activated protein C (APC) prevents blood clots from growing too large by inactivating factor V. </s>

<s>[INST] Is Factor V Leiden thrombophilia inherited ? [/INST] How is factor V Leiden inherited? Factor V Leiden is a genetic condition and can be inherited from a parent. It is important to understand that each person inherits two copies of every gene, one from their mother and the other copy from their father. Individuals who inherit one copy of the factor V Leiden mutation from a parent are called heterozygotes. Heterozygotes have a 50% chance with each pregnancy of passing the mutated gene to their offspring (and therefore they also have a 50% chance of having a child who does not inherit the gene mutation). People who inherit two copies of the mutation, one from each parent, are called homozygotes. Homozygotes will always pass one copy of the mutated gene to their offspring. If both parents are heterozygotes (carry one factor V Leiden mutation) than they would have a 25% chance of having a child with two factor V Leiden mutations, a 25% chance of having a child with no mutations, and a 50% chance of having a child with one mutation. </s>

<s>[INST] How to diagnose Factor V Leiden thrombophilia ? [/INST] How is factor V Leiden thrombophilia diagnosed? No clinical features (signs and/or symptoms) are specific for factor V Leiden thrombophilia. The diagnosis of factor V Leiden thrombophilia requires a coagulation screening test or DNA analysis of F5, the gene for factor V, to identify the specific mutation that causes this condition. The APC (activated protein C) resistance assay, a coagulation screening test, measures the anticoagulant response to APC. This screening test has a sensitivity and specificity for factor V Leiden approaching 100%. The sensitivity of a test is a measure of the test's ability to detect a positive result when someone has the condition, while the specificity is a measure of the test's ability to identify negative results.Targeted mutation analysis (a type of DNA test) of the F5 gene for the Leiden mutation is considered definitive and has a mutation detection frequency of approximately 100%. This means that approximately all individuals who have the factor V Leiden mutation will be detected by this genetic test. It is generally recommended that individuals who test positive by another means should then have the DNA test both for confirmation and to distinguish heterozygotes (individuals with a mutation in one copy of the gene) from homozygotes (individuals with mutations in both copies of the gene). </s>

<s>[INST] What are the treatments for Factor V Leiden thrombophilia ? [/INST] How might factor V Leiden be treated? The management of individuals with factor V Leiden depends on the clinical circumstances. People with factor V Leiden who have had a deep venous thrombosis (DVT) or pulmonary embolism (PE) are usually treated with blood thinners, or anticoagulants. Anticoagulants such as heparin and warfarin are given for varying amounts of time depending on the person's situation. It is not usually recommended that people with factor V Leiden be treated lifelong with anticoagulants if they have had only one DVT or PE, unless there are additional risk factors present. Having had a DVT or PE in the past increases a person's risk for developing another one in the future, but having factor V Leiden does not seem to add to the risk of having a second clot. In general, individuals who have factor V Leiden but have never had a blood clot are not routinely treated with an anticoagulant. Rather, these individuals are counseled about reducing or eliminating other factors that may add to one's risk of developing a clot in the future. In addition, these individuals may require temporary treatment with an anticoagulant during periods of particularly high risk, such as major surgery. Factor V Leiden increases the risk of developing a DVT during pregnancy by about seven-fold. Women with factor V Leiden who are planning pregnancy should discuss this with their obstetrician and/or hematologist. Most women with factor V Leiden have normal pregnancies and only require close follow-up during pregnancy. For those with a history of DVT or PE, treatment with an anticoagulant during a subsequent pregnancy can prevent recurrent problems. </s>

<s>[INST] What is (are) Loeys-Dietz syndrome ? [/INST] Loeys-Dietz syndrome is a connective tissue disorder that causes aortic aneurysms, widely spaced eyes (hypertelorism), cleft palate and/or split uvula (the little piece of flesh that hangs down in the back of the mouth) and twisting or spiraled arteries (arterial tortuosity). Other findings include craniosynostosis, extropia (eyes that turn outward), micrognathia, structural brain abnormalities, intellectual deficit, and congenital heart disease. Signs and symptoms vary among individuals. This condition is inherited in an autosomal dominant manner with variable clinical expression. This condition is called Loeys-Dietz syndrome type 1 when affected individuals have cleft palate, craniosynostosis, and/or hypertelorism. Individuals without these features are said to have Loeys-Dietz syndrome type 2. The disease is caused by mutations in the TGFBR1, the TGFBR2, the SMAD3 or the TGFB2 genes. It is important to have an early and adequate treatment for the heart problems because the chance for aortic dissection and other vascular problems may be high in some patients. Many specialists may be involved for the best managment of the patient. </s>

<s>[INST] What is (are) Ovarian sex cord tumor with annular tubules ? [/INST] An ovarian sex cord tumor with annular tubules (SCTAT) is a tumor that grows from cells in the ovaries known as sex cord cells. As these cells grow, they form tube-like shapes in the tumor. SCTATs can develop in one or both ovaries, and may cause symptoms such as puberty at an exceptionally young age (precocious puberty), irregular menstrual cycles, or post-menopausal bleeding. Most ovarian SCTATs are benign. However, because there is a chance that an SCTAT may be malignant, treatment may include surgery to remove the tumor. </s>

<s>[INST] What causes Ovarian sex cord tumor with annular tubules ? [/INST] What causes an ovarian sex cord tumor with annular tubules? Approximately one third of ovarian sex cord tumors with annual tubules (SCTATs) develop because of an underlying genetic condition called Peutz Jeghers syndrome (PJS), which is caused by a mutation in the STK11 gene. In these genetic cases, many small SCTATs develop in both ovaries and are almost always benign. The remaining two thirds of ovarian SCTATs are not related to a genetic condition and develop as a single tumor in one ovary; up to 25% of SCTATs in this group may be malignant. Ovarian SCTATs not related to PJS have no known cause and are believed to occur by chance. </s>

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

<s>[INST] What causes Charcot-Marie-Tooth disease type 2F ? [/INST] What causes Charcot-Marie-Tooth disease type 2F? Charcot-Marie-Tooth disease type 2F (CMT2F) is caused by mutations in the HSPB1 gene. This gene provides instructions for making a protein (heat shock protein beta-1) which helps protect cells under adverse conditions. Heat shock proteins appear to be involved in activities such as cell movement, stabilizing the cell's framework, folding and stabilizing new proteins, repairing damaged proteins, and muscle contraction. Heat shock protein beta-1 is particularly abundant in nerve and muscle cells. In nerve cells, it helps to organize a network of threads that maintain the diameter of axons (neurofilaments), which are needed to transmit nerve impulses efficiently. It is unclear exactly how HSPB1 mutations lead to the axon abnormalities characteristic of CMT2F. Researchers suggest that mutations lead to an altered protein which clusters together and interferes with nerve cell function. Another possibility is that the altered protein disrupts the assembly of neurofilaments, which in turn may impair the transmission of nerve impulses. </s>

<s>[INST] Is Charcot-Marie-Tooth disease type 2F inherited ? [/INST] How is Charcot-Marie-Tooth disease type 2F inherited?

<s>[INST] What is (are) Metachromatic leukodystrophy ? [/INST] Metachromatic leukodystrophy is an inherited condition characterized by the accumulation of fats called sulfatides in cells, especially cells of the nervous system. This accumulation results in progressive destruction of white matter of the brain, which consists of nerve fibers covered by myelin. Affected individuals experience progressive deterioration of intellectual functions and motor skills, such as the ability to walk. They also develop loss of sensation in the extremities, incontinence, seizures, paralysis, inability to speak, blindness, and hearing loss. Eventually they lose awareness of their surroundings and become unresponsive. This condition is inherited in an autosomal recessive pattern and is caused by mutations in the ARSA and PSAP genes. </s>

<s>[INST] Is Metachromatic leukodystrophy inherited ? [/INST] How is metachromatic leukodystrophy inherited? Metachromatic leukodystrophy is inherited in an autosomal recessive manner. This means that both copies of the disease-causing gene in each cell must have a mutation for an individual to be affected. Individuals inherit two copies of each gene - one copy from each parent. Typically, an individual is affected because they inherited a mutated copy of the gene from each parent. Individuals with one mutated copy of the gene (such as an unaffected parent of an affected individual) are referred to as carriers; carriers typically do not have any signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) chance to have the condition, a 50% (1 in 2) chance to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier. </s>

<s>[INST] How to diagnose Metachromatic leukodystrophy ? [/INST] Who might consider genetic carrier testing for a family history of metachromatic leukodystrophy? If someone has a family history of metachromatic leukodystrophy (MLD) or someone is known to be a carrier for MLD, individuals who are biologically related to the affected individual or carrier are at risk to be a carrier. Generally speaking, the more closely related an individual is to the affected individual or carrier, the greater the chance for that person to be a carrier. Prior to genetic testing, the chance to be a carrier for some biological relatives of an affected individual are as follows: Parent of affected individual: assumed to be 100% (called an obligate carrier) Unaffected sibling of affected individual: 2 in 3 (~66.6%) Aunt or uncle of affected individual: 1 in 2 (50%) First cousin of affected individual: 1 in 4 (25%) If someone has carrier testing and is found to be negative (not a carrier), that person's children are typically assumed to be negative also. More information about the use of genetic carrier testing is available on GeneTests' Web site and can be viewed by clicking here. Individuals who are interested in learning about genetic testing and about their specific risk to be a carrier should speak with a genetics professional. </s>

<s>[INST] What is (are) Pili torti ? [/INST] Pili torti is a rare hair condition characterized by fragile hair. In pili torti hair has a flattened shaft with clusters of narrow twists at irregular intervals. Some cases may be inherited in autosomal dominant or autosomal recessive patterns, while others are acquired. In the inherited form, symptoms tend to be present from early childhood. It can occur alone or as part of other diseases like ectodermal dysplasias, Menke disease, Bjornstand syndrome, or Bazex syndrome. Acquired cases of pili torti may be associated with anorexia nervosa, malnutrition, oral retinoid treatment, or inflammatory scalp conditions (e.g., cutaneous lupus erythematousus). If pili torti is detected, it is necessary to investigate possible neurological disorders, hearing loss, and defects in the hair, nails, sweat glands and teeth. There is no specific treatment for this condition, but it may improve spontaneously after puberty. Click here to visit Medscape and view an image of a child with pili torti. </s>

<s>[INST] What is (are) Liddle syndrome ? [/INST] Liddle syndrome is a rare, inherited form of high blood pressure (hypertension). The condition is characterized by severe, early-onset hypertension associated with decreased levels of potassium, renin and aldosterone in blood plasma. Children usually have no symptoms; adults can present with symptoms of low potassium levels (hypokalemia) such as weakness, fatigue, muscle pain (myalgia), constipation or palpitations. It is caused by mutations in either the SCNN1B or SCNN1G genes and is inherited in an autosomal dominant manner. Treatment may include a low sodium diet and potassium-sparing diuretics to reduce blood pressure and normalize potassium levels. Conventional anti-hypertensive therapies are not effective. </s>

<s>[INST] What causes Liddle syndrome ? [/INST] What causes Liddle syndrome? Liddle syndrome is caused by mutations (changes) in either of two genes: SCNN1B and SCNN1G . The SCNN1B gene provides instructions for making one piece (the beta subunit) of protein complexes called epithelial sodium channels (ENaCs). The SCNN1G gene provides instructions for making a different piece (the gamma subunit) of ENaCs. These channels are found at the surface of certain cells called epithelial cells in many tissues of the body, including the kidneys, lungs, and sweat glands. The ENaC channel transports sodium into cells. Mutations in the SCNN1B and SCNN1G genes associated with Liddle syndrome affect an important region of the protein involved in signaling for its breakdown (degradation). As a result of the mutations, the protein is not tagged for degradation, and more ENaC channels remain at the cell's surface. The increase in channels at the cell surface abnormally increases the reabsorption of sodium, which leads to hypertension. Removal of potassium from the blood is linked with reabsorption of sodium into the blood, so excess sodium reabsorption leads to hypokalemia. </s>

<s>[INST] Is Liddle syndrome inherited ? [/INST] How is Liddle syndrome inherited? Liddle syndrome is inherited in an autosomal dominant manner. This means that only one mutated copy of the disease-causing gene in each cell is sufficient to cause the condition. The mutated copy of the gene may be inherited from an affected parent or occur for the first time in an affected individual. Individuals with an autosomal dominant condition have a 50% (1 in 2) risk to pass the mutated copy of the gene on to each of his/her children. </s>

<s>[INST] How to diagnose Liddle syndrome ? [/INST] How is Liddle syndrome diagnosed? A diagnosis of Liddle syndrome may first be suspected by the detection of early-onset hypertension (high blood pressure), especially in the presence of family history. The diagnosis may then be confirmed by special blood and urine tests which show hypokalemia (low blood potassium levels), decreased or normal plasma levels of renin and aldosterone, metabolic alkalosis with high sodium plasma levels, and low rates of urinary excretion of sodium and aldosterone with high rates of urinary potassium excretion. The diagnosis can be further confirmed by genetic testing. </s>
