Our aim is to investigate the correlation between 9p21 chromosome rs4977574 polymorphism genotypes and the development of coronary artery heart disease (CHD). Two hundred and eighty-nine patients with angiography-confirmed CHD were recruited as the CHD group, while 338 subjects without CHD symptoms were enrolled as the control group. For all participating subjects, the genotypes of rs4977574 polymorphism were examined by the real-time PCR analysis. Analyses acquired from single-locus technique showed that genotype distribution of rs4977574 polymorphism was significantly different (p = 0.041) between CHD group and the control group. Logistic regression analysis demonstrated that rs4977574 polymorphism in a dominant mode significantly increased (p = 0.038) the risk of CHD, where odds ratio (OR) was 0.71 and the 95 % confidence interval (CI) 0.58–0.97 was applied. 9p21 chromosome rs4977574 polymorphism genotypes are associated with the incidence and development of CHD. The presence of C allele may reduce the risk of CHD.
