PURPOSE Behcet's disease (BD) is a multisystemic immunoinflammatory disorder characterized by mucocutaneous, ocular, vascular, and central nervous system manifestations. The common methylene tetrahydrofolate reductase (MTHFR) gene C677T mutation is a known risk factor for thrombosis. The aim of this study was to investigate the MTHFR gene C677 mutation in patients with BD and evaluate if there ...
Prostate cancer is the most common cause of cancer death in men and is a major health problem worldwide. Methylene tetrahydrofolate reductase (MTHFR) plays an important role in folate metabolism and is also an important source of DNA methylation and DNA synthesis (nucleotide synthesis). To assess the association and interaction of genotypic polymorphisms in MTHFR and lifestyle factors with pros...
PURPOSE Methylenetetrahydrofolate reductase (MTHFR) has been implicated in lung cancer risk and response to platinum-based chemotherapy in advanced non-small cell lung cancer (NSCLC). However, the results are controversial. We performed meta-analysis to investigate the effect of MTHFR C677T polymorphism on lung cancer risk and response to platinum-based chemotherapy in advanced NSCLC. MATERIA...
Association between neural tube defects (NTDs) and C677T polymorphism of the methylenetetrahydrofolate reductase (MTHFR) gene was suspected, because the MTHFR gene codes for a key enzyme in folate metabolism. Its deficiency usually leads to significant reductions in plasma concentrations of folate, vitamin B(12) and methionine, whereas homocysteine levels are increased. We examined folate, vita...
OBJECTIVE Several studies with contradictory results from different cultures about association of methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism in schizophrenia and bipolar disorders. Little is known about this association in Arab culture and Egypt. So the present study aimed to assess the association of MTHFR C677T polymorphism in bipolar disorder (BD) and schizophrenia in com...
The aim of this study was to examine the association of homozygosity for the methylenetetrahydrofolate reductase (MTHFR) C677T mutation and vitamin B12 deficiency in 360 asymptomatic individuals and to investigate forearm endothelial function in C677T homozygotes. MTHFR C677T mutation and levels of vitamin B12, folic acid, and homocysteine were measured in study participants. Frequency of homoz...
It is suggested that hyperuricemia is a marker of cardiovascular risk in human adults with metabolic syndrome (MS). The C677T polymorphism in the gene encoding the enzyme methylenetetrahydrofolate reductase (MTHFR) is associated with hyperuricemia. Data on factors associated with uricemia in human adults with MS genotyped for this polymorphism are lacking. We aimed to investigate the factors as...
The authors performed a meta-analysis of studies examining the association between polymorphisms in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene, including MTHFR C677T and A1298C, and common psychiatric disorders, including unipolar depression, anxiety disorders, bipolar disorder, and schizophrenia. The primary comparison was between homozygote variants and the wild type for MTHFR ...
The distribution of factor V Leiden G1691A, II G20210A, MTHFR C677T, and H1299R polymorphisms known to predispose thrombophilia in 215 cases 40 controls admitted with indication recurrent pregnancy loss (RPL) was investigated. Genotyping performed by melting curve analysis using simultaneous PCR (RT-PCR). There no difference between genotype allele frequencies the case control groups terms exam...
BACKGROUND/AIMS Hyperhomocyst(e)inaemia has been identified as a strong risk factor for stroke, myocardial infarction, and deep vein thrombosis. A point mutation of methylene tetrahydrofolate reductase (MTHFR C677T) has been associated with increased plasma homocyst(e)ine levels. To investigate whether hyperhomocyst(e)inaemia and/or MTHFR C677T mutation are associated with non-arteritic ischaem...
