Background: Tuberculosis remains a global public health problem. Genetic polymorphisms may affect the susceptibility, clinical characteristics, and adverse drug reactions of patients with TB. The present study aimed to examine the association of single nucleotide polymorphisms of lncRNA-HNF1B-3:1 with the clinical manifestation of TB in a Western Chinese population.
Method: A total of 526 tuberculosis patients and 561 healthy subjects were recruited in Western China. The correlation between lnc-HNF1B-3:1 polymorphism and tuberculosis susceptibility was investigated. Moreover, the influence on adverse drug reactions following treatment was explored. A total of 7 SNPs within the lnc-HNF1B-3:1 locus was genotyped by the improved multiplex ligation detection reaction method.
Results: No significant associations were noted between TB susceptibility and the presence of all 7 SNPs of the lnc-HNF1B-3:1 as determined by single-locus analysis (All P > .05). The AA genotype of rs12939622 (in the dominant model) and the AA genotype of rs4262994 (in the recessive model) caused increased susceptibility of the subjects to fever (P < .001 and P = .008, respectively). The Rs2542670 G allele was associated with increased risk of thrombocytopenia, leukopenia, and chronic kidney damage following drug administration (P = .007, .029, .003, respectively).
Conclusion: The present study reported for the first time that the rs12939622, rs4262994 and rs2542670 genotypes in lnc-HNF1B-3:1 locus may influence the clinical manifestations of tuberculosis.
