Evaluation of the Association between the C677T Polymorphism of Methylenetetrahydrofolate Reductase Gene and Recurrent Spontaneous Abortion
Introduction: One factor known to cause thrombophilia in women with unexplained recurrent spontaneous abortion (RSA) is C677T polymorphism of methylenetetrahydrofolate reductase gene. This study aimed to determine the association between RSA and MTHFR C677T polymorphism in Iranian patients. Methods: In this case-control study, 30 patients with previous history of two or more consecutive unexpla...
متن کاملMethylenetetrahydrofolate reductase C677T polymorphism and cognitive function in older women.
Homocysteine may play a causal role in cognitive decline. The authors analyzed the 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T genotype, a correlate of plasma homocysteine levels, among 6,653 participants in the Study of Osteoporotic Fractures, a community-based, prospective cohort study of older women in four US states. During the years 1986-1998, the authors assessed whether the di...
متن کاملMethylenetetrahydrofolate reductase (MTHFR) C677T polymorphism in psoriasis in southern Turkey*
Background: Psoriasis is a multigenic and multifactorial dermatological disease linked to cardiovascular diseases. Increased levels of homocysteine in patients with psoriasis have been demonstrated in many studies. The most frequently investigated genetic defect that plays a role in homocysteine metabolism is single point substitution (C to T) located on the 677th nucleotide of the methylenetet...
متن کاملIs methylenetetrahydrofolate reductase C677T polymorphism associated with hyperuricemia?
Several epidemiological studies have examined the relationship of the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism with hyperuricemia. However, the results were controversial. We therefore conducted a large cross-sectional study (2,219 subjects) and an updated meta-analysis by combining previous studies (9,502 subjects) to provide more empirical evidence for the association. A...
متن کاملC677T gene polymorphism of methylenetetrahydrofolate reductase (MTHFR) in meningiomas and high-grade gliomas.
BACKGROUND Methylenetetrahydrofolate reductase (MTHFR) plays a role in DNA biosynthesis, methylation and repair in actively dividing cells by acting on folate metabolism. A common C677T polymorphism in the gene for MTHFR leads to an enzyme with decreased activity. MTHFR polymorphisms have been studied in various cancers but not in primary brain tumors. The purpose of this case-control study was...
