Relationship of MTHFR Gene 677C→T Polymorphism, Homocysteine, and Estimated Glomerular Filtration Rate Levels With the Risk of New-Onset Diabetes

Abstract: East Asian patients with diabetes have a higher risk for renal complications and strokes than Europeans. We aimed to evaluate the effect of methylenetetrahydrofolate reductase (MTHFR) gene 677C→T polymorphism, which was associated with a higher stroke risk and was common in the Chinese population, as well as homocysteine and estimated glomerular filtration rate (eGFR) levels on the risk of new-onset diabetes (NOD). A total of 2422 subjects without diabetes were followed-up for 7 years. NOD was defined as fasting plasma glucose ≥7.0 mmol/L or self-reported physician diagnosis of diabetes. Compared with subjects with MTHFR 677CC genotype, those with TT genotype had a higher risk of NOD in females (odds ratio 2.78, 95% confidence interval 1.39–5.56) but not in males (0.80, 0.40–1.61, P for interaction = 0.008). Furthermore, MTHFR 677C→T polymorphism was more strongly associated with the risk of NOD among females with higher body mass index (BMI, ≥23 vs
