Aims: To explore the association between six single-nucleotide polymorphisms in OLR1, PON1, MTHFR gene and the angiographical characteristics of coronary atherosclerosis to determine if any of the conventional factors correlate with genetic polymorphisms in the advent of the disease. Methods: We examined rs1801131, rs1801133, rs3736232, rs3736234, rs854563 and rs662 by TaqMan® SNP Genotyping Assays in 1075 subjects that underwent angiography. The angiographical characteristics of coronary atherosclerosis were defined by the Gensini Score system. Results: The T allele of rs1801133 was associated with coronary atherosclerosis severity with the OR = 1.49, 95% CI = 1.04-2.14. In MTHFR gene, haplotype T-A was a susceptibility haplotype to coronary atherosclerosis (OR = 1.27, 95% CI = 1.06-1.51) whereas haplotype C-A had a protective effect (OR = 0.83, 95% CI = 0.70-0.99). In addition, several synergistic effects between rs1801133 and conventional risk factors such as diabetes and smoking were found. Conclusions: Collectively, the results demonstrate that the T allele of rs1801133 conferred an increased risk for coronary atherosclerosis. The MTHFR C-A haplotype was a protective haplotype, while T-A haplotype was a susceptibility haplotype. The presence of the T allele of rs1801133 increases the odds of coronary atherosclerosis severity when associated with conventional risk factors.
