Although we have detected the association of the rs1333040, rs1333042, rs4977574, rs2066715 and rs2740483 SNPs on chromosome 9p21 and ABCA1 and the risk of CHD and IS, other genetic variants are not detected and analyzed together, and this may result in some misinterpretation of our results. The gene discussed is ABCA1; the disease is coronary artery disorder.
