Abstract

We investigated polymorphisms of methylenetetrahydrofolate reductase (MTHFR) and cystathionine &bgr;-synthase (CBS) genes in Korean patients with coronary artery disease (CAD) and identified a new polymorphism (c→t) in intron 7 of the CBS gene using the single-strand conformation polymorphism method. No significant differences were found in allele frequencies for either gene between the CAD and normal groups although the frequency of the so-called thermolabile MTHFR polymorphism, a proposed risk factor for CAD, was higher in Koreans than in other populations studied. The relatively low incidence of CAD in Korea suggests that this MTHFR polymorphism is not causative in this population.
