Abstract

Abstract: Background: The aim of our study was to investigate the association of leptin ( LEP) gene (rs11761556, rs12706832, rs2167270), leptin receptor ( LEPR ) gene (rs1137100, rs1137101, rs1805096) variants and pulmonary tuberculosis (PTB) susceptibility, as well as their several clinical manifestations, in a Chinese population. Methods: This study included a cohort of 489 PTB patients and 489 healthy controls, and six SNPs were genotyped by improved multiple ligase detection reaction (iMLDR). Results: We found that there were no significant differences regarding the allele and genotype frequencies of LEP rs11761556, rs12706832, rs2167270, LEPR rs1137100, rs1137101, rs1805096 between PTB patients and healthy controls (all P > 0.05), as well as the results of the dominant model and recessive model (all P > 0.05). In the LEP gene, the rs11761556 AA genotype frequency was significantly associated with the development of fever and pulmonary infection in PTB patients ( P = 0.035, P = 0.049). In addition, the relation between main haplotypes and PTB patients was also analyzed, but only haplotype CAG in LEP was significantly associated with PTB susceptibility ( P = 0.012). Conclusions: LEP and LEPR heritable variation were not contribute to the pathogenesis of PTB in Chinese. While rs11761556 variant might associate with several clinical features of PTB. Highlights: LEP gene rs11761556, rs12706832, rs2167270 variants were not contribute to the pathogenesis of PTB. LEPR gene rs1137100, rs1137101, rs1805096 variants were not related to PTB susceptibility. LEP gene rs11761556 variant might associate with fever and pulmonary infection of PTB.
