Objective: To investigate the association of programmed cell death 1(PD-1), T cell immunoglobulin mucin 3 (TIM-3) and triggering receptor expressed on myeloid cells-1 (TREM-1) genes polymorphisms with pulmonary tuberculosis susceptibility. Methods: In this case-control study, peripheral venous blood of 100 pulmonary tuberculosis patients (pulmonary tuberculosis group) in the Jintan People's Hospital of Changzhou and of community physical examination volunteers (health control group) was collected from Mar 2015 to Sep 2016. A total of 66 single nucleotide polymorphisms (SNP) in PD-1, TIM-3 and TREM1 sequences were selected and SNP genotype and allele frequency were analyzed using the next-generation sequencing technology. Association of these SNP with pulmonary tuberculosis susceptibility was investigated using linkage disequilibrium (LD) analysis and genetic models. Results: Among these 66 SNP, 24 SNP with Hardy-Weinberg equilibrium P (HWE-P) value <0.001 or minimum allele frequency (MAF) <0.05 were kicked out. The remaining 42 SNP were analyzed with LD analysis and genetic models. There was no significant difference in genotype frequencies between pulmonary tuberculosis group and health control group (all P>0.05). Five SNP (rs41435650, rs28539662, rs13023138, rs75565781, rs36084323) in PD-1 were identified in a significant haplotype (TACGC) between pulmonary tuberculosis group and health control group (P=0.014). Among these haplotypes, strong LD was observed between rs28539662 and rs75565781 (r(2)=0.871), as well as rs36084323 (r(2)=0.864). Rs75565781 showed highest correlation with rs36084323 (r(2)=0.966). Conclusion: These SNP in PD-1, TIM-3 and TREM-1 genes are not associated with the susceptibility of pulmonary tuberculosis.
