- There are many combinations of MTHFR: 1  Homozygous: means you have both copies of either the 677 mutation, or the 1298 mutation, one from from each parent. 2  Heterozygous: means you have one copy of either the 677 mutation, or the 1298 mutation, plus a normal one from the other parent.ore than one mutation of the MTHFR gene. Genes are passed down by your mother and your father. Most literature states there are a good 40-50 different mutations of this important gene which could be passed down by one, or both or your parents.

MTHFR C677T Mutation Basics The MTHFR C677T mutation affects the enzyme methylenetetrahydrofolate reductase, which is the rate-limiting enzyme in the formation of 5-methyltetraydrofolate (5-MTHF), or methylfolate.If you have the C677T mutation, your ability to convert folic acid into methylfolate is significantly reduced.levated homocysteine levels can cause oxidative stress and increase your risk of heart disease. Genetic Testing You can easily find out if you have the MTHFR C677T mutation by ordering a DNA test kit from 23andMe ($99). Once you receive your results, go to Genetic Genie for methylation analysis (free).

Useful For Direct mutation analysis for the MTHFR A1298C mutation should be reserved for patients with coronary artery disease, acute myocardial infarction, peripheral vascular artery disease, stroke, or venous thromboembolism, who have increased basal homocysteine levels or an abnormal methionine-load test.MTHFR C677T).he MTHFR A1298C reduces MTHFR activity to a lesser extent than C677T, but compound heterozygous A1298C/C677T may develop hyperhomocysteinemia. Hyperhomocysteinemia is an independent risk factor for coronary artery disease, acute myocardial infarction, peripheral arterial disease, stroke, and venous thromboembolism.

MTHFR Mutation If a person has two copies (homozygous) of MTHFR C677T, or has one copy of C677T and one of A1298C, then it is likely that elevated homocysteine levels are due to these inherited mutations, or that the mutations are contributing to them.he MTHFR mutation test may sometimes be ordered when a person has elevated homocysteine levels, especially when the person has a personal or family history of premature cardiovascular disease or thrombosis.

MTHFR Mutation Symptoms, Diagnoses & Natural Remedies According to the Genetics Home Reference Library, MTHFR is a gene that provides the body with instructions for making a certain enzyme called methylenetetrahydrofolate reductase. In fact, “MTHFR” is the shortened name for this enzyme. There are two main MTHFR mutations that researchers focus on most often.

Methylenetetrahydrofolate reductase At nucleotide 1298 of the MTHFR, there are two possibilities: A or C. 1298A (leading to a Glu at amino acid 429) is the most common while 1298C (leading to an Ala substitution at amino acid 429) is less common. 1298AA is the normal homozygous, 1298AC the heterozygous, and 1298CC the homozygous for the variant.he MTHFR nucleotide at position 677 in the gene has two possibilities: C (cytosine) or T (thymine). C at position 677 (leading to an alanine at amino acid 222) is the normal allele.

- MTHFR gene mutation is a genetic change that affects an enzyme involved in breaking down the amino acid homocysteine. About 33% of Americans have one copy of a common MTHFR gene mutation (C677T). Having one copy of C677T or one copy of another common mutation A1298C is not associated with significant health risks.

A year and a half ago I was tested and the papers read Homozygous MTHFR C677T: To copies of the MTHFR gene mutation C677T were detected but the A1298C mutation was not identified.So now I do not know what to do. It is revision sinus surgery and the Dr told me it would take about an hour. year and a half ago I was tested and the papers read Homozygous MTHFR C677T: To copies of the MTHFR gene mutation C677T were detected but the A1298C mutation was not identified.

MTHFR gene variant Coronary artery disease, blood clots, and stroke are conditions 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.

- If you see a +/+ for any mutation, this means you are homozygous for that mutation. If you see +/- for a mutation, this means you are heterozygous for that mutation. A -/- means you do not have that mutation. Overview of MTHFR Mutations The two most common MTHFR mutations are C677T and A1298C.ere is a brief overview of each type of mutation: MTHFR C677T If you are either heterozygous or homozygous for the MTHFR C677T mutations, your body has trouble converting folic acid into the active form of folate in the body.

Diabetes, Type 2  In-Depth Report Polymorphisms in the MTHFR gene have also been studied as possible risk factors for a variety of common conditions. These include heart disease, stroke, high blood pressure (hypertension), high blood pressure during pregnancy (preeclampsia), an eye disorder called glaucoma, psychiatric disorders, and certain types of cancer.

If the MTHFR mutation test is negative, then the C677T and A1298C mutations were not detected and the tested person's elevated homocysteine level is likely due to another cause.

Homocystinuria due to MTHFR deficiency Homocystinuria due to MTHFR deficiency is caused by mutations in the MTHFR gene. This gene tells the body how to make an enzyme, also called MTHFR. MTHFR is important for a chemical reaction in the body involving forms of the vitamin folate.

- What you have are two copies of the A1298C MTHFR mutation which means you have a defective BH4 pathway and this can lead to a multitude of symptoms. Neurological, mental, muscular and sensitivity to chemicals are common for this mutation.ou are right – each of you donated one copy each of C677T to your son. What you don’t know is if you have another copy of C677T making your MTHFR mutation more severe. You also may have a copy of A1298C which would make you compound heterozygous.

The fastest, easiest way to test for MTHFR mutations. In addition, individuals with mutations in the MTHFR gene often have elevated levels of homocysteine in their blood. This is related to a deficiency of folic acid (folate or Vitamin B) and is connected to increased risk of cardiac events.he MTHFR enzyme helps the body to manufacture proteins. Mutations in the MTHFR gene are associated with thromboembolic and cardiovascular disease, which can lead to blood clots, strokes, embolisms, and heart attacks. Two mutations of MTHFR are the most common.

MTHFR Mutation When a person has two copies of the MTHFR C677T gene mutation (homozygous) or one copy of MTHFR C677T and one copy of A1298C (compound heterozygous), decreased MTHFR enzyme activity slows down the homocysteine-to-methionine conversion process and can lead to a buildup of homocysteine in the blood.he methylenetetrahydrofolate reductase (MTHFR) gene contains the DNA code to produce the MTHFR enzyme. This test detects two of the most common mutations. When there are mutations or variations in the MTHFR gene, it can lead to serious genetic disorders such as homocystinuria, anencephaly, spina bifida, and others.
