What are the signs and symptoms of Leiomyoma of vulva and esophagus? The Human Phenotype Ontology provides the following list of signs and symptoms for Leiomyoma of vulva and esophagus. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Clitoromegaly - Esophageal obstruction - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
KBG syndrome is a rare condition characterized mainly by skeletal abnormalities, distinctive facial features, and intellectual disability. Specific signs and symptoms may include delayed bone age; abnormalities of the bones of the spine, ribs, and/or hands; large teeth (macrodontia); short stature; developmental delay; and behavioral or emotional issues. Less common features may include hearing loss, seizures, and congenital heart defects. In some cases, KBG syndrome is caused by a mutation in the ANKRD11 gene and is inherited in an autosomal dominant manner. In other cases, the genetic cause is unclear. Some affected people inherit the condition from a parent, while in other people it occurs sporadically.

MTHFR gene mutation is a genetic change that disrupts the production of an enzyme that plays an important role in breaking down the amino acid homocysteine (a building block of protein). These mutations may cause a mild to severe loss of activity of this enzyme that can lead to elevated levels of homocysteine in the blood and/or urine. Some rare MTHFR gene mutations severely impair the function of this enzyme and lead to homocystinuria, an autosomal recessive condition characterized by various health problems including abnormal clotting and neurological problems (developmental delay, seizures, intellectual disability and microcephaly). Common MTHFR gene mutations (such as C677T and A1298C) lead to a milder reduction in enzyme function. People with two copies of C677T or one copy of C677T and one copy of A1298C may have an increased risk for cardiovascular conditions such as coronary artery disease, blood clots, and stroke. Many people who inherit these mutations never develop one of the associated conditions.
What are the signs and symptoms of MTHFR gene mutations? People with MTHFR gene mutations may develop elevated levels of homocysteine in their blood (homocysteinemia) or urine (homocystinuria). Risks for health effects vary depending on the levels of homocysteine. A few cases of severe homocysteinemia have been due to rare MTHFR gene mutations (sometimes in combination with a second common MTHFR gene mutation). Symptoms in these patients varied greatly but often involved pronounced neurological symptoms and blood vessel disease. The age of the patients when they first experienced symptoms varied from infancy to adulthood. Common MTHFR gene mutations cause less severe, although still significantly raised levels of homocysteine. The most well studied MTHFR mutation, is C677T. An estimated 11% of Americans carry two copies of this mutation. People with two copies of C677T have higher homocysteine levels, than those without the mutation (people with one copy of C677T may have mildly raised homocysteine levels).  Many studies have investigated the health effects of high homocysteine levels and/or having two C677T MTHFR gene mutations. Some studies suggest that an elevated level of homocysteine in the blood is associated with an increased risk for heart disease, including coronary heart disease and stroke. Specifically, studies have estimated that people with two C677T MTHFR mutations have a 16% higher chance of developing coronary heart disease, when compared to people without these mutations. Weaker associations have been suggested between high homocysteine levels and narrowing of the carotid arteries (the arteries on each side of your neck), blood clots in deep veins (often in the lower leg and thigh), a sudden blockage in a lung artery, and pregnancy complications (such as preeclampsia, placental abruption, fetal growth restriction, stillbirth, and neural tube defects). Studies involving MTHFR and homocysteine and the following conditions have been completed, but with conflicting and varied results:* Hypertension Hyperlipidemia Psoriasis Infertility Recurrent pregnancy loss Downs syndrome Spina bifida Parkinson disease Alzheimer disease Migraine Cerebral venous thrombosis Psychiatric disorders Schizophrenia Breast cancer Cervical cancer Ovarian cancer Esophageal cancer Oral cancer Liver cancer Pancreatic cancer Prostate cancer Bladder cancer Lung cancer Stomach cancer Colorectal cancer Acute lymphoblastic leukemia *This is not an exhaustive list of all studies involving MTHFR and health effects.
How is a MTHFR gene mutation inherited? Because each person has two copies of the MTHFR gene, people can inherit one copy of the MTHFR mutation or two copies (one from each parent). People who inherit two copies of a common MTHFR gene mutation (for example two C677T mutations or a C677T mutation and a A1298C mutation) may have an increased risk for certain conditions such as coronary artery disease, blood clots, and stroke when compared to those without the mutations and elevated homocystine levels. Coronary artery disease, blood clots, and stroke are all complex conditions and are caused by a combination of many genetic and environmental factors. Some rare MTHFR gene mutations can lead to homocystinuria, which is inherited in an autosomal recessive manner. Visit our "Homocystinuria due to MTHFR deficiency" webpage.
Is genetic testing available to detect MTHFR gene mutations? Yes. Genetic testing is available for MTHFR gene mutations. This testing can be used in people with suspected homocystinuria or to determine the cause of elevated homocysteine levels in the blood. Genetic testing for C677T and A1286C may be indicated in a person with elevated homocysteine levels and one or more of the following, coronary artery disease venous thromboembolism stroke heart attack peripheral artery disease aneurysm high blood pressure recurrent pregnancy loss However, the American Heart Association recommends against testing for the common MTHFR gene mutations (C677T and A1298C) as a screen for increased risk of cardiovascular conditions. The College of American Pathologists and the American College of Medical Genetics recommend against testing for C677T and A1298C in people with blood clots. This is because the relationship between C677T and A1298C mutations and risk for cardiovascular disease is not completely understood. 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 might a MTHFR gene mutation be treated? High homocysteine levels in the body may occur if the MTHFR enzyme is not functioning normally due to MTHFR mutations, such as C677T and A1298C. Currently there are no treatments to remove adverse risks associated with MTHFR gene mutations. However, elevated levels of homocysteine can also occur if there is a lack of folate or B vitamins. Homocysteine levels also tend to rise with age, smoking, and use of certain drugs (such as carbamazepine, methotrexate, and phenytoin). It is important to ensure that people with and without MTHFR gene mutations receive adequate amounts of naturally occurring folate, choline, and B vitamins (B12, B6, and riboflavin) to mitigate nutritional risks. If adequate nutrition cannot be attained through diet alone, supplementation with folate (e.g., levomefolate (5-methyl THF) or folinic acid) and B vitamins is considered. We recommend that you talk to your doctor to learn if supplementation would benefit you. Smoking cessation and, when possible, avoidance of medications that adversely affect homocystiene level are additional management strategies.

Juvenile primary lateral sclerosis is a rare disorder characterized by progressive weakness and stiffness of muscles in the arms, legs, and face. This disorder damages motor neurons, which are specialized nerve cells in the brain and spinal cord that control muscle movement. Symptoms begin in early childhood and progress over a period of 15 to 20 years. Juvenile primary lateral sclerosis is caused by mutations in the ALS2 gene. It is inherited in an autosomal recessive pattern.

What causes juvenile primary lateral sclerosis? Juvenile primary lateral sclerosis is caused by mutations in the ALS2 gene. The ALS2 gene provides instructions for making a protein called alsin. Alsin is abundant in motor neurons, but its function is not fully understood. Mutations in the ALS2 gene alter the instructions for producing alsin. As a result, alsin is unstable and decays rapidly, or it is disabled and cannot function properly. It is unclear how the loss of functional alsin protein damages motor neurons and causes juvenile primary lateral sclerosis.
Sarcoidosis is an inflammatory disease characterized by the development and growth of tiny lumps of cells called granulomas. If these tiny granulomas grow and clump together in an organ, they can affect how the organ works, leading to the symptoms of sarcoidosis. The granulomas can be found in almost any part of the body, but occur more commonly in the lungs, lymph nodes, eyes, skin, and liver. Although no one is sure what causes sarcoidosis, it is thought by most scientists to be a disorder of the immune system. The course of the disease varies from person to person. It often goes away on its own, but in some people symptoms of sarcoidosis may last a lifetime. For those who need treatment, anti-inflammatory medications and immunosuppressants can help.
What are the signs and symptoms of Sarcoidosis? Many people who have sarcoidosis don't have symptoms. Others may feel like they are coming down with the flu or a respiratory infection. While almost any body part or system can be affected, the lungs are most commonly involved. If granulomas form in the lungs, symptoms may include shortness of breath (dyspnea), a cough that won't go away, and chest pain. Some people feel very tired, uneasy, or depressed. Night sweats and weight loss are also common.      Sarcoidosis can also cause the following:   Skin rashes, ulcers or discoloration   Joint stiffness or pain   Enlarged lymph nodes   Enlarged liver or spleen   Vision problems, eye dryness or irritation   Headaches, seizures, or weakness on one side of the face   Aches and pains in the muscles and bones   Abnormal heart beats   Kidney stones The Human Phenotype Ontology provides the following list of signs and symptoms for Sarcoidosis.

What causes sarcoidosis? No one yet knows what causes sarcoidosis. It is thought by most scientists to be a disorder of the immune system, where the body's natural defense system malfunctions. Some physicians believe that sarcoidosis may result from a respiratory infection caused by a virus. Others suspect that exposure to toxins or allergens in the environment is to blame. It's also possible that some people have a genetic predisposition to developing sarcoidosis, which, when combined with an environmental trigger, produces the disease. Studies are ongoing to investigate the genetic and environmental components of this disease.
