In previous studies, only HLA-B*13:01 was strongly associated with DHS in leprosy Han Chinese (odds ratio 122.1, p-value = 6.038 × 10−12 and odds ratio 20.53, p-value = 6.84 × 10−25) and dapsone-induced DRESS in non-leprosy Thais (odds ratio = 60.75, p-value = 0.0001) (25–27). This evidence concerns the gene HLA-B and leprosy.
