Abstract

We conducted a study to investigate the role of three IL-17 gene single nucleotide polymorphisms (SNP) (rs2275913G>A, rs3748067C>T, and rs763780 T>C) in the development of gastric cancer. A total of 252 patients with gastric cancer and 252 control subjects were collected between May 2012 and May 2014. The SNP genotyping of IL-17A rs2275913G>A and rs3748067C>T and IL-17F rs763780 T>C was performed using the Sequenom MassARRAY platform (Sequenom, San Diego, CA, USA) according to the manufacturer instructions. By conditional regression analysis, individuals carrying the AA and the GA+AA genotypes of rs2275913G>A were correlated with an elevated risk of gastric cancer when compared with those carrying the GG genotype, and the adjusted ORs (95%CIs) were 2.05 (1.13-3.76) for the AA genotype and 1.45 (1.03-2.08) for the GA+AA genotype. In conclusion, our results suggest that the IL-17A rs3748067C>T and IL-17F rs763780 T>C polymorphisms play an important role in the risk of gastric cancer in a Chinese population.
