Genetic Polymorphisms of Il-17a in Association With the Risk of Pulmonary Tuberculosis in Iraqi Patients

Abstract

Objectives: Tuberculosis (TB) is an infectious disease that usually affects the lungs caused by Mycobacterium tuberculosis, TB is the second biggest killer, globally. The aim of this study was to examine the association between IL-17A rs2275913 SNP and pulmonary TB susceptibility in Iraqi population.Methods: From January 2017 to April 2017, 80 pulmonary TB patients were selected as the case group, another 40 healthy control were enrolled as the control group. The genotype frequencies of IL-17A rs2275913 was detected using amplification refractory mutation system.Results: The results of IL-17A serum level demonstrated that there were significant differences (p<0.05) between patients groups. The result showed that A allele have a higher frequency (55% vs. 50%) in TB patients than the control sample with OR value of 1.22 and EF value 0.1 and G have lower frequency (45% vs. 50%) in TB patients than control sample with OR value of 0.82 with PF value of 0.09, but this difference was not statistically significant (p>0.05).Conclusion: There were no significant associations between IL-17A rs2275913 polymorphism and risk of TB in Iraqi population.
