MTHFR C677T Polymorphism and Migraine Risk: A meta-analysis.

This meta-analysis was undertaken to review the current evidence available examining the link between the MTHFR C677T polymorphism and migraine risk across numerous populations. 17 studies were used for this review, with a total of 8903 cases and 27, 637 controls. Collective results showed the 677T allele was significantly associated with an increased risk for total migraine in Asian populations.
