No Association of MicroRNA-146a rs2910164 Polymorphism and Risk of Primary Gout Development in Chinese Han Populations: A Case-control Study

Previous studies demonstrated that MicroRNA-146a (miR-146a) plays an important role in the regulation of autoinflammatory diseases including primary gout. The G/C polymorphism (rs2910164) in the precursor sequence of miR-146a caused its stem region to change from G: U to C: U,which can contribute to the susceptibility of human diseases. However, no genetic relevance studies of miR-146a gene polymorphisms to gout have been reported by now.The purpose of this study was to analyze the association between the miR-146a rs2910164 genetic polymorphism and the susceptibility of the Chinese Han population to primary gout.1130 Chinese Han participants (including 606 primary gout patients and 524 gender and age-matched healthy control subjects) were recruited and the 5'exonuclease TaqMan® technology was used to perform miR-146a rs2910164 genotyping.After statistical analysis, no significant differences were observed between gout patients and healthy controls in genotype and allele frequency.Our results indicate that there is no evidence for the involvement of the miR-146a rs2910164 polymorphisms in susceptibility to primary gout in the Chinese Han population.
