Similar results for DRB1*04 were reported by Joko et al. (2000) for leprosy per se in a Japanese population [30] and, more recently, by both Vanderborght et al. (2007) in both Brazilian and Vietnamese populations [14] and Motta et al. (2007) in an Argentinean population [31]. This evidence concerns the gene HLA-DRB1 and leprosy.
