Subsequently, associations between leprosy and the HLA-DR-DQ region, LACC1, CCDC122, and the I602S functional SNP in the Toll-like receptor 1 (TLR1) gene were replicated in an Indian population [108, 109] and between the HLA-DR-DQ, RIPK2, CCDC122, LACC1, and NOD2 in Vietnam [110]. This evidence concerns the gene TLR1 and leprosy.
