Association between CYP1A1 genetic polymorphisms and coronary artery disease in Uygur population in Xinjiang, China / 中华流行病学杂志

ABSTRACT

Objective To assess the association between human CYP1A1 gene polymorphisms and coronary artery disease (CAD) among the Uygur population of China.Methods Genotypes of CYP1A1 single nucleotide polymorphisms (SNPsrs4886605,rs 12441817,rs4646422 and rs1048943) were detected by real-time PCR in 293 CAD patients and 408 controls.Results Among the Uygur group,distribution of genotypes and allele of rs4886605 were both significantly different between CAD and the controls (all P＜0.05).The dominant model (CC vs.CT + TT) of rs4886605 was significantly lower among CAD patients than in controls.Significant differences were retained after the adjustment was made in all the participants (OR=0.368,95％CI0.185-0.530,P=0.018) and in men (OR=0.350,95％CI0.235-0.568,P=0.015).Distributions of genotypes and allele of rs12441817 were both significantly different between CAD and the controls (all P＜0.05).The dominant model (TT vs.CT+CC) of rs12441817 was significantly lower among patients CAD than in controls.Significant difference were retained after the adjustment was made,in total participants (OR=0.253,95％ CI0.231-0.546,P=0.016) and in men (OR=0.241,95％ CI0.132-0.478,P=0.002).Conclusion Both rs4886605 and rs12441817 SNPs of the CYP1A1 gene were associated with CAD in the Uygur population of China.
