To investigate the single and combined associations between single-nucleotide polymorphisms (SNPs) and the development of leprosy, we therefore performed generalized multi-analytical (GMDR) analysis in Chinese leprosy household contacts and constructed a risk prediction model.Patients and Methods: This case–control study included 229 leprosy cases and 233 healthy household contacts in Zhejiang province, China. Participants were genotyped for 17 polymorphisms selected from GWAS. The Pearson χ2 test, logistic regression and GMDR analysis were performed to investigate gene–gene interactions and construct a risk prediction model for leprosy.Results: The genotype and the allele distributions of rs142179458, rs2275606, rs663743 and rs73058713 were significantly different between patients and controls. rs2275606, rs6478108, rs663743 and rs73058713 showed an association after adjusting for sex and age in the logistic regression. A five-way interaction model consisting of rs2058660, rs2275606, rs4720118, rs6478108 and rs780668 was chosen as the optimal model for determining leprosy susceptibility. The model classified 237 (51.3%) into the low-risk group and 225 (48.7%) individuals into the high-risk group. The area under the curve (AUC) of this model was 0.757 (95% CI: 0.712– 0.803), and the odds ratio for leprosy between the high- and low-risk groups was 9.733 (95% CI: 6.384– 14.960; P< 0.001). The sensitivity and specificity of the model were observed to be 74.7% and 76.8%, respectively.Conclusion: Our results suggest that rs2058660, rs2275606, rs4720118, rs6478108 and rs780668, five SNPs with a significant sole effect on leprosy, interact to confer a higher risk for the disease in leprosy household contacts (HHCs).Keywords: leprosy, gene–gene interactions, generalized multi-analytical, risk stratificationhttps://www.dovepress.com/single-nucleotide-polymorphisms-in-genes-predisposing-to-leprosy-in-le-peer-reviewed-article-PGPMleprosygene–gene interactionsgeneralized multi-analyticalrisk stratification |
