Association of and and methylenetetrahydrofolate reductase C677T allele with type 2 diabetes.

Background And Objectives: Type 2 diabetes is a multifactorial disorder that results from the interaction between genetic predisposition and environmental factors. Different (body constitution) individuals have different susceptibility for the diseases, and this is determined by both genetic and environmental factor. This study was undertaken to determine the association status of Methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C with type 2 diabetes and .

Materials And Methods: After informed consent, 54 patients with type 2 diabetes and 56 individuals as normal controls were analyzed. Their constitution and pathological data were collected and MTHFR C677T and A1298C genotypes were determined.

Results: / were associated and found to be strong risk factors (Chi-square test = 39.67, < 0.00001, odds ratio [OR] = 16.133, 95% confidence interval [CI] = 6.32-41.20) for type 2 diabetes. MTHFR C677T was associated (Chi-square test = 7.743, = 0.02) with type 2 diabetes where the major CC genotype was found to be a risk for type 2 diabetes (OR = 3.78, 95% CI = 1.14-12.45). A1298C was not associated with type 2 diabetes (Chi-square test = 2.264, = 0.322). None of the was associated with C677T and A1298C variants.

Interpretation And Conclusion: In the present study, an extremely strong association between (/) and type 2 diabetes ( < 0.00001) was detected. The present study gives a strong clue for the association of (body constitutional) and clinical phenotype.
