So far, dozens of variants associated with leprosy have been identified through Genome-wide association studies (GWAS) and candidate-gene studies in the Chinese population, such as those in CCDC122, LACC1 (previously C13orf31), NOD2, TNFSF15, HLA-DR-HL-DQ, RIPK2, IL23R, RAB32, BCL10, IL18RAP/IL18R1, and IL12B [16–22]. Here, LACC1 is linked to leprosy.
