To assess the association of variations in chemokines (CCL5, CCL2), chemokine receptor (CCR5 and CCR2) genes with susceptibility to myocardial infarction (MI) through a case-control study.


Genotypes of patients with MI (n = 634) were compared with those of controls (n = 601). Genetic polymorphisms of CCL5 rs2107538 (-403G > A), CCL2 rs1024611 (-2518A > G), CCR5 rs333 ( δ 32 ins or del) and CCR2 rs1799864 (190G > A) of 1235 individuals were determined with polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Particular genotypes were confirmed with DNA sequencing.


No subject was found to carry the CCR5 - δ 32 allele. No association was found between CCL2 rs1024611 and CCR2 rs1799864 polymorphisms and MI. For CCL5 rs2107538 polymorphism, the A allele has occurred at a higher frequency in MI patients than controls, and its AA genotype has been associated with a significantly increased risk of MI independent of conventional risk factors (OR = 3.346, 95%CI = 1.938-5.775, P < 0.01, AA vs. GG). Further analysis indicated that MI patients had significantly more A-403 - A-2518 haplotype (CCL5 -403G > A and CCL2 -2518A > G, 21.8% vs. 26.6%, OR = 1.229, 95%CI = 1.012-1.493, P = 0.038) and AA or AA genotype (CCL5 -403G > A - CCL2 -2518A > G, 5.0% vs. 12.1%, OR = 3.245, 95%CI = 1.780-5.914, P < 0.01).


Although our data dose not support an association between CCL2 rs1024611, CCR2 rs1799864 and CCR5 rs333 polymorphisms and MI, genetic variation in CCL5 gene may still be a useful marker for assessing susceptibility to MI in ethnic Han Chinese population.
