What does it mean to be heterozygous for MTHFR?
Some people have a genetic mutation in 1 or both of their MTHFR genes. People with a mutation in 1 MTHFR gene are are said to be heterozygous; if mutations are present in both genes, the person is said to be homozygous or compound heterozygous for the mutation(s).
What is A1298C heterozygous mutation?
The A1298C mutation, like the C677T mutation, results in a decrease in MTHFR activity that is more pronounced in the homozygous (CC) than in the heterozygous (AC) or normal (AA) states, and does not result in a thermolabile protein.
Is MTHFR gene mutation hereditary?
Everyone has two MTHFR genes, one inherited from your mother and one from your father. Mutations can occur in one or both MTHFR genes. There are different types of MTHFR mutations. An MTHFR test looks for two of these mutations, also known as variants.
How serious is MTHFR mutation?
At least 40 mutations in the MTHFR gene have been identified in people with homocystinuria, a disorder in which the body is unable to process homocysteine and methionine properly. People with this condition often develop eye problems, abnormal blood clotting, skeletal abnormalities, and learning problems.
How is MTHFR A1298C treated?
How to treat the MTHFR gene mutation? The doctor may suggest supplementation to address deficiencies, along with medications or treatments to address the specific health condition. Treatments for any disease caused by the MTFR mutation (e.g., for depression antidepressants) may be prescribed.
How common is A1298C?
7 to 14 percent
However, a 2015 study found that A1298C is found in 7 to 14 percent in North American, European, and Australian populations. In comparison, the variant is far less common in Hispanic and Asian populations.
What happens if you have the C677T gene mutation?
If you have the C677T gene mutation only you will have predominate problems such as: Folate metabolism (using your folate and other synergistic nutrients or nutrients that work with folate. Such as your other b vitamins for example) Homocysteine cycle (very important chemical reactions that protect the body from serious diseases.
Is C677T homozygous or heterozygous?
Other research confirms that both homozygous C677T (T677T) and compound heterozygous (C677T + A1298C) are linked with higher homocysteine concentrations and greater risk of heart disease ( 10 ). It was concluded that a heterozygous A1298C mutation on its own does not influence heart disease risk.
What is the c667t and A1298C gene mutation?
Some people are diagnosed with both the C667t and the A1298C gene mutations, simply put this means that they have a combination of the above problems which means that the right treatments are even more important.
What are the treatment recommendations for C677T MTHFR mutations?
Here are the common recommendations for supporting those with C677T MTHFR mutations: Limit ingestion of folic acid in fortified foods as you cannot process folic acid well. Limit or cease taking supplements or drugs with folic acid in them. Talk with your doctor before stopping. Avoid folic acid blocking drugs such as birth control or Methotrexate.
