In view of the prevailing controversy about the role of Methylenetetrahydrofolate reductase (MTHFR) C677T mutation in stroke and paucity of studies from India, this study has been undertaken to evaluate MTHFR C677T gene polymorphism in consecutive ischemic stroke patients and correlate these with folic acid, homocysteine (Hcy) and conventional risk factors.

The folate-sensitive polymorphism methylenetetrahydrofolate reductase (MTHFR) c. 677 C > T (A222V) referred a non-significant risk of ischemic stroke (odds ratio: 1.20) in all patients, and homozygosity for MTHFR c. 677 C > T was associated with an earlier onset of stroke selectively in patients younger than 60 years (38 +/- 3 years vs. 45 +/- 1 years; P = 0.043).
