The C677T Polymorphism in MTHFR Is Not Associated with Migraine in Portugal
نویسندگان
چکیده
Migraine is a debilitating disorder affecting a large proportion of the population. The effect of methylenetetrahydrofolate reductase (GeneID: 4524) polymorphisms in migraine etiology and development has been a theme of great interest. Several populations were evaluated with contradictory results. In this case-control study, we investigated the effect of the C677T polymorphism in MTHFR, as a genetic risk factor for migraine, in the Portuguese population. We observed that, overall, there was no significant difference in the frequencies of MTHFR C677T genotypes or of the T-allele among the Portuguese migraineurs when compared to controls. There was also no association of migraine with aura with MTHFR genotypes or with the T-allele, in contrast with previous studies. Regarding the risk of the T-allele homozygote carriers, there was an equal probability to develop migraine with aura over migraine without aura in our patients. Thus, we conclude that the C677T MTHFR polymorphism, responsible for a reduction of the MTHFR activity in folate metabolism, is not a major genetic susceptibility factor for migraine in the Portuguese population.

Methylenetetrahydrofolate Reductase Gene Variant (MTHFR C677T) and Migraine: A Case Control Study and Meta-analysis
BACKGROUND Migraine is a common disorder that often coexists with depression. While a functional polymorphism in methyleneterahydrofolate reductase gene (MTHFR C677T) has been implicated in depression; the evidence to support an association of MTHFR with migraine has been inconclusive. We aim to investigate the effect of this variant on propensity for migraine and to perform a systematic review...

Background: The 5, 10-methyleneterahydrofolate reductase (MTHFR) and methionine synthase reductase (MTRR) are two essential enzymes involved in folate metabolism. The relationship between genetic polymorphisms and congenital heart defects (CHDs) is inconsistent. Our aim was to investigate the association between two well-known polymorphisms of MTHFR and MTRR genes, C677T and A66G, respectively,...

Background: Methylenetetrahydrofolate reductase (MTHFR) is one of the key enzymes in the metabolism of folate, and the mutation of C677T leads to reduction of MTHFR enzyme activity and increases the risk of cardiovascular diseases. The aim of this study was to investigate the association between C677T polymorphism in MTHFR gene and some non-genetic factors and varicose veins. Methods: In this ...

Background and purpose: Coronary artery disease (CAD) is a complex disease that is caused by both environmental and genetic factors. Methylenetetrahydrofolate (MTHFR) enzyme is associated with metabolism of homocysteine and its impaired function is considered as a risk factor for developing CAD. Some variants are involved in decreased activity of MTHFR and its deficiency. The polymorphism of C6...
