Furthermore, HLA-DRB1*1601 (9.0% vs. 1.8%; P = 0.0016; OR = 5.81; CI = 2.05–16.46) was associated with susceptibility to borderline leprosy compared to control group, and while HLA-DRB1*08 (11.2% vs. 1.2%; P = 0.0037; OR = 12.00; CI = 1.51 – 95.12) was associated with susceptibility to lepromatous leprosy, when compared to tuberculoid leprosy, DRB1*04 was associated to protection. This evidence concerns the gene HLA-DRB1 and lepromatous leprosy.
