The observed association of the rs3750920 T allele to CL in this study is in line with the association with leprosy [34] Shah et al. showed that the rs5743899 GG genotype is associated with increased levels of the proinflammatory cytokine IL-6, low levels of IL-10 and decreased TOLLIP mRNA expression while the rs3750920 TT genotype was associated with high TOLLIP mRNA expression but with no correlation with the levels of either IL-6 or IL-10 [23]. Here, IL10 is linked to leprosy.
