Résumé
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 (SNPs:rs4886605,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％CI:0.185-0.530,P=0.018) and in men (OR=0.350,95％CI:0.235-0.568,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％ CI:0.231-0.546,P=0.016) and in men (OR=0.241,95％ CI:0.132-0.478,P=0.002).Conclusion Both rs4886605 and rs12441817 SNPs of the CYP1A1 gene were associated with CAD in the Uygur population of China.
