Risk for leprosy associated with the DRB1*10 allele has been described in Turkish, Vietnamese, and Brazilian populations [17, 36], whereas the HLA-DRB1*14 allele was associated with the TT group in a population from north-eastern Brazil [42] and DRB1*14:01 and DRB1*14:06 were associated with leprosy per se in Argentinean population [37]. This evidence concerns the gene HLA-DRB1 and leprosy.
