[17] The SDF1 SNP rs1801157 is associated with premature CAD in Chinese patients.[18] Since SDF1 and its cognate receptors CXCR4 and CXCR7 are involved in myocardial repair and are associated with outcome in cardiovascular patients we aimed to investigate clinically significant SDF1 SNPs for their prognostic impact in patients with cardiovascular disease. The gene discussed is CXCR4; the disease is coronary artery disorder.
