The methylenetetrahydrofolate reductase (MTHFR) 677C %26gt; T and 1298A %26gt; C polymorphisms, which are associated with hyperhomocysteinemia and nitric oxide (NO) deficiency (which is related to atherothrombosis and cerebral ischemia), have not been studied in moyamoya disease. A case-control study was performed to investigate whether the MTHFR 677C %26gt; T and 1298A %26gt; C polymorphisms contribute to moyamoya disease (MMD). %26lt;br%26gt;One hundred and seven Korean patients with MMD (mean age, 20.85 +/- 15.89 years; 66.4 % female) and 232 healthy control subjects (mean age, 23.99 +/- 16.16 years; 56.8 % female) were included. Genotyping for the MTHFR 677C %26gt; T and 1298A %26gt; C polymorphisms and measurements of homocysteine, folate, vitamin B-12, and NO in the cerebrospinal fluid (CSF) were performed. The statistical analysis was performed by multivariate linear regression and logistic regression. %26lt;br%26gt;The MTHFR 677CT+TT genotype frequency was significantly increased with early-onset MMD (%26lt; 10 years) compared with late-onset MMD (a parts per thousand yen10 years) (adjusted odds ratio, 3.392; 95 % confidence interval, 1.294-8.893, P = 0.013). The MTHFR 677C-1298C/677T-1298A diplotype (1.71 +/- 1.23 arbitrary units) presented significantly lower NO levels in the CSF compared with the 677C-1298A/677C-1298A diplotype (11.40 +/- 12.24 arbitrary units). %26lt;br%26gt;The MTHFR 677C %26gt; T and 1298A %26gt; C polymorphisms have restricted roles in the Korean MMD population. Therefore, further studies involving larger and more heterogeneous cohorts are needed to extend our understanding of the influence of polymorphisms in MTHFR and other thrombophilic genes on MMD.
