ABSTRACT: In order to investigate the association of G+1688A (Ser563Asn) polymorphism of platelet endothelial cell adhesion molecule-1 (PECAM-1) gene with myocardial infarction (MI) in the Chinese Han population, the G+1688A polymorphism in PECAM-1 gene was detected by polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) method among 502 subjects, including 218 patients with MI and 284 controls. The results showed that there was significant difference in AA frequencies of genotype G+1688A polymorphism between case and control groups (39% vs 24%, P<0.001). A similar trend was observed on the allele frequencies (A/G: 62% vs 49%, P<0.001). Among the subjects with high serum total cholesterol level or high systolic blood pressure level, the variant AA genotype was associated with high risk of MI (adjusted OR, 2.13; 95% CI, 1.08-4.41 and adjusted OR, 2.53; 95%CI, 1.63-3.63). The single nucleotide polymorphism (SNP) at position +1688 in the exon 8 of PECAM-1 gene was associated with MI and the allele A might be a risk factor for MI in the Chinese Han population.
