Abstract

Vascular inflammation has been shown to be involved in the pathogenesis of intracranial aneurysms (IA). MiRNAs are key molecules that participate in the regulation of many important biological processes including inflammation. Studies on the hsa-miR-146a rs2910164 polymorphism and its association with different inflammatory related diseases have engendered inconsistent results, and until now, there have been no reports on the association between this polymorphism and the susceptibility to IA. In this study, we aimed to investigate whether the rs2910164 polymorphism is involved in the process of IA. We genotyped 164 patients with IA and 478 healthy controls using a polymerase chain reaction-restriction fragment length polymorphism assay. All subjects were Chinese. The distributions of rs2910164 genotypes and alleles between patients with IA and healthy controls were similar [CG vs CC: odds ratio (OR) = 0.701, 95% confidence interval (CI) = 0.456-1.080; GG vs CC: OR = 0.920, 95%CI = 0.524-1.617; G vs C: OR = 0.939, 95%CI = 0.731-1.208, respectively]. No association was found between the hsa-miR-146a rs2910164 polymorphism and the risk of IA in the analyzed population.
