What is MTHFR polymorphism?
A common polymorphism in the gene coding for the 5,10-methylene tetrahydrofolate reductase (MTHFR) (C677T, Ala –> Val) is associated with a decreased activity of the enzyme due to thermolability.
How does folate affect DNA synthesis?
Moreover, folate affects gene expression by regulating cellular S-adenosylmethionine (SAM) levels. There is convincing evidence that folate modulates both DNA synthesis and repair and DNA hypomethylation with altered gene expression in vitro.
What is the MTHFR gene describe its function?
The MTHFR gene provides instructions for making an enzyme called methylenetetrahydrofolate reductase. This enzyme plays a role in processing amino acids, the building blocks of proteins. Methylenetetrahydrofolate reductase is important for a chemical reaction involving the vitamin folate (also called vitamin B9).
Can MTHFR cause autoimmune disorders?
1 The MTHFR mutation is also believed to predispose a person to certain cancers, birth defects, and autoimmune diseases.
What happens if I have MTHFR?
If you have an MTHFR mutation, your MTHFR gene may not work right. This may cause too much homocysteine to build up in the blood, leading to various health problems, including: Homocystinuria, a disorder that affects the eyes, joints, and cognitive abilities. It usually starts in early childhood.
What does folate do to DNA?
Folates are essential for the synthesis of DNA, the modification of DNA and RNA, the synthesis of methionine from homocysteine, and various other chemical reactions involved in cellular metabolism. These reactions are collectively known as folate-mediated one-carbon metabolism.
Does L Methylfolate cause weight gain?
In addition, L-methylfolate augmentation did not lead to any significant differences in terms of gastrointestinal side effects, sedation, weight gain, and sexual dysfunctions.
Can you take folic acid and vitamin B12 together?
No interactions were found between folic acid and Vitamin B12. This does not necessarily mean no interactions exist. Always consult your healthcare provider.
