Objective: Chronic inflammation play an important role on abdominal aortic aneurysms (AAA) formation. Chemokine receptor-2 (CCR2) is involved in regulation of the inflammatory response. However, relation between CCR2 polymorphism and AAA formation in human has not yet been investigated. In this study, we aimed to investigate the relationship between AAA and CCR2-V64I gene polymorphism. Methods: In this study, 100 consecutive patients with AAA and 138 individuals with normal aortic diameter were included. CCR2-V64I gene polymorphism were analyzed by PCR-RFLP technique. Genotype distribution and allele frequencies of CCR2-V64I gene polymorphism in patients with AAA and healthy subjects were compared. Results: CCR2 heterozygote V64I polymorphism and allele frequency were more frequently observed in the AAA group (p = 0.01, p = 0.004). Significant relationship was observed between CCR2 V64I polymorphism (OR:2.31, 95% CI:1.19-4.46, p = 0.01) and presence of AAA in multivariate regression analysis. Conclusion: The present study, showed us a relationship between CCR2-V64I polymorphism and AAA.
