Topic: MTHFR gene mutation
Question: What is (are) MTHFR gene mutation ?
Answer: 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.

Topic: MTHFR gene mutation
Question: What are the symptoms of MTHFR gene mutation ?
Answer: 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.

Topic: MTHFR gene mutation
Question: Is MTHFR gene mutation inherited ?
Answer: 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.

Question: How to diagnose MTHFR gene mutation ?
Answer: 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.

Question: What are the treatments for MTHFR gene mutation ?
Answer: 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.

Topic: Myelofibrosis
Question: What is (are) Myelofibrosis ?
Answer: Myelofibrosis is a disorder of the bone marrow, in which the marrow is replaced by fibrous (scar) tissue. Scarring of the bone marrow causes anemia, which can lead to fatigue and weakness, as well as pooling of the blood in abnormal sites like the liver and spleen, causing these organs to swell. Although myelofibrosis can occur at any age, it typically develops after the age of 50. In most cases, myelofibrosis gets progressively worse. Treatment is aimed at relieving signs and symptoms and may include medications, blood transfusions, chemotherapy, radiation therapy and surgery.

Topic: Achondrogenesis
Question: What is (are) Achondrogenesis ?
Answer: Achondrogenesis is a group of severe disorders that are present from birth and affect the development of cartilage and bone. Infants with achondrogenesis usually have a small body, short arms and legs, and other skeletal abnormalities that cause life-threatening complications.  There are at least three forms of achondrogenesis, type 1A, type 1B and type 2, which are distinguished by signs and symptoms, pattern of inheritance, and the results of imaging studies such as x-rays (radiology), tissue analysis (histology), and genetic testing.  Type 1A and 1B achondrogenesis are both inherited in an autosomal recessive pattern.  Type 1B may be caused by mutations in the SLC26A2 gene.  Type 2 achondrogenesis is inherited in an autosomal dominant pattern and is caused by new (de novo) mutations in the COL2A1 gene.

Topic: Achondrogenesis
Question: What causes Achondrogenesis ?
Answer: What causes achondrogenesis? Research has shown that changes (mutations) in the SLC26A2 and COL2A1 genes cause achondrogenesis types 1B and 2, respectively. The genetic cause of achondrogenesis type 1A remains unknown.  The SLC26A2 gene provides instructions for making a protein that is important for the normal development of cartilage and for the conversion of cartilage to bone. The COL2A1 gene provides instructions for making a protein that forms a type of collagen found mostly in cartilage and in the clear gel that fills the eyeball (vitreous).  Mutations in these genes result in the production of proteins that are unable to properly perform their jobs within the body.

Topic: Achondrogenesis
Question: Is Achondrogenesis inherited ?
Answer: How is achondrogenesis inherited? Achondrogenesis type 1A and type 1B are believed to be inherited in an autosomal recessive pattern.  Autosomal recessive inheritance means both copies of the gene in each cell have mutations.  Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show signs and symptoms of the condition. Achondrogenesis type 2 is considered an autosomal dominant disorder because one copy of the altered gene in each cell is sufficient to cause the condition. It is almost always caused by new (de novo) mutations and typically occurs in people with no history of the disorder in their family.
