Genetic polymorphisms of IL17A, TLR4 and P2RX7 and associations with the risk of chronic obstructive pulmonary disease

Publication date: May–June 2018 Source:Mutation Research/Genetic Toxicology and Environmental Mutagenesis, Volumes 829–830 Author(s): Yaoyao Dai, Zhihai Zhang, Lina Xu, Yunfei Shang, Rongrong Lu, Jie Chen We investigated the association between genetic polymorphisms of IL17A, TLR4 and P2RX7 genes and chronic obstructive pulmonary disease (COPD) in a Han population. We performed a case-control study with 152 COPD subjects from the Third People’s Hospital of Nantong in 2015. Healthy controls were selected from a group of people attending the physical examination and were frequency-matched to the cases by sex and age. Genotyping was performed using TaqMan allelic discrimination technology. A logistic regression model was used to calculated odds ratios (OR) and 95% confidence intervals (CI). After Bonferroni correction, polymorphisms rs2275913 and rs763780 in the IL17A gene, rs10759932 and rs2737190 in the TLR4 gene, and rs1718119 in the P2RX7 gene were significantly associated with altered risk for COPD. Individuals carrying rs2275913 allele A had a reduced risk (OR 0.62; 95% CI: 0.46–0.86). Individuals carrying rs763780 allele C had an increased risk (OR 1.96; 95% CI: 1.29–2.98). Individuals carrying rs10759932 allele C had a reduced risk (OR 0.49; 95% CI: 0.34–0.73). Individuals carrying rs2737190 allele G had a reduced risk (OR 0.51; 95% CI: 0.37–0.71). Individuals carrying rs1718119 allele A had a reduced risk (OR 0.69; 95% CI: 0.45–1.06).Genetic poly...
