AIM:To study the relation of cystathionine β-synthase(CBS)G919A and C572T gene mutations with coronary heart disease(CHD).METHODS:Sixty-four CHD patients and thirty healthy subjects from Guangxi were recruited.CBS G919A and C572T genotypes were analyzed by Allele-specific amplification(ASA).RESULTS:Significant differences in the genotype and A alleles frequency distribution of CBS G919A between the two groups were observed(P<0.01).No significant difference in the genotype and T alleles frequency distributio...
