Influence of interleukin-17 gene polymorphisms on the development of pulmonary tuberculosis.
We conducted a case-control study in a Chinese population to examine the correlations between interleukin (IL)-17 gene polymorphisms and tuberculosis (TB) development. The study population included 336 TB subjects and 351 control subjects who were enrolled between June 2012 and June 2014. Genotyping analyses of IL-17A rs2275913 and rs3748067 and IL-17F rs763780 were analyzed using polymerase chain reaction-restriction fragment length of polymorphism. The genotype distributions of IL-17 rs2275913 were found to be in Hardy-Weinberg equilibrium in the controls, while the IL-17 rs3748067 and rs763780 were not. Based on unconditional logistic regression, individuals carrying the AA genotype and GA + AA genotype of rs2275913 were more likely to have a significantly increased risk of TB compared to subjects with the GG genotype. The ORs (95%CI) for the AA genotype and GA + AA genotype were 2.20 (1.35-3.60) and 1.52 (1.11-2.09), respectively. The CC genotype and TC + CC genotype of rs763780 were associated with increased risk of TB when compared with the TT genotype. The ORs (95%CI) for the CC genotype and TC + CC genotype were 1.99 (1.05-3.87) and 1.58 (1.07-2.33), respectively. In conclusion, rs763780 may play a critical role in the etiology of TB.
