Altered folate and vitamin B12 metabolism in families with spina bifida offspring.
Folic acid intake reduces the risk of neural tube defects (NTDs). Although the 677C-->T mutation in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene is a risk factor for NTDs, it only partly explains the elevated homocysteine levels in mothers of children with NTDs. We measured vitamin B12, folate and homocysteine in patients with spina bifida (SB), their parents, and in controls, to i...
متن کاملMyocardial Infarction in a Young Patient with Methylene Tetrahydrofolate Reductase (mthfr) Gene Mutation
Modifiable risk factors for CHD include high blood pressure, high blood cholesterol, smoking, obesity, physical inactivity, diabetes, and stress. When a patient presents with the typical features of CHD (like ours) but do not have the modifiable risk factors, genetic causes should be considered. A limited number of genetic variants are proven to be independent risk factors for thromboembolism. ...
متن کاملMethylene-tetrahydrofolate reductase contributes to allergic airway disease
RATIONALE Environmental exposures strongly influence the development and progression of asthma. We have previously demonstrated that mice exposed to a diet enriched with methyl donors during vulnerable periods of fetal development can enhance the heritable risk of allergic airway disease through epigenetic changes. There is conflicting evidence on the role of folate (one of the primary methyl d...
متن کاملSegmental renal artery thrombosis secondary to methylene tetrahydrofolate reductase mutation: an unusual presentation.
Methylene tetrahydrofolate reductase (MTHFR) is an enzyme involved in the metabolism of homocysteine to methionine, and folic acid is an essential cofactor. Mutations in the MTHFR gene lead to hyperhomocysteinemia and vascular thrombosis. Heterozygous mutation involving a single nucleotide polymorphism in the MTHFR gene leading to vascular thrombosis is very rare. We present a case of segmental...
متن کاملMethylene tetrahydrofolate reductase gene mutation together with anticardiolipin antibody during pregnancy: a case report.
CONTEXT High plasmatic homocysteine levels have been associated with arterial and venous thrombosis. The C677T methylene tetrahydrofolate reductase (MTHFR) gene mutation is one of the known causes for high homocysteine levels in plasma. Anticardiolipin antibody (ACA) is also associated with thrombosis and, along with other clinical complications such as recurrent abortion and stillbirth, is par...
