It has been recognized that some people have a genetic variant which leads to elevated levels of homocysteine and impairs ability to process folate. This condition was recognized as independent risk factor of coronary heart disease. Recently, connection between this termolabile mutation of the methylenetetrahydrofolate reductase and numerous conditions and diseases has been established. Aim of ...
Periconceptional folate supplementation reduces the risk of neural-tube defects. We studied the frequency of the 677C-->T mutation in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene in 55 patients with spina bifida and parents of such patients (70 mothers, 60 fathers). 5% of 207 controls were homozygous for the 677C-->T mutation compared with 16% of mothers, 10% of fathers, and 13% of...
C entral retinal vein occlusion (CRVO) in the young is also known as papillophlebitis and is a rare presentation.1 Retinal vein occlusion has been known to be associated with many systemic conditions.1,2 Association of hyperhomocysteinemia with retinal vein occlusion was reported in the literature.2-4 There was controversy, however, over whether there was correlation between methylenetetrahydro...
Statistical studies have demonstrated that various agents may reduce the risk of cancer's development. One of them is activity of flavin-dependent enzymes such as flavin-containing monooxygenase (FMO)(GS-OX1), FAD-dependent 5,10-methylenetetrahydrofolate reductase and flavin-dependent monoamine oxidase. In the last decade, many papers concerning their structure, reaction mechanism and role in t...
The activities of 5-methyltetrahydrofolate (5-CH3THF) related enzymes and DNA polymerase alpha were determined in bone marrow cells obtained from patients with vitamin B12 deficient megaloblastic anemia and compared with those from healthy volunteers and patients with hemolytic anemia. 5-CH3THF homocysteine methyltransferase activity was significantly lower than that in the control subjects. 5,...
