To study genetic mutations of methylenetetrahydrofolate reductase C677T and cystathioinine-β-synthase T833C related to homocysteine metabolism in patients with ischemic stroke, the MTHFR gene C677T gene mutation and the CBS T833C gene mutation were detected by PCR-RFLP or ARMS method in 74 patients with ischemic stroke and 83 normal people for control. Results showed that the frequencies of MTHFR genet homogenetic type(2.7%), heterogenetic type(51.4%) and T allele(28.4%) in ischemic group were higher than those in control group(1.2%, 39.8% and 21.1%, respectively).
