Further evidence for this finding was provided by Chung et al. (2004) in the Han-Chinese population, where presence of HLA-B*15:02 was strongly associated with CBZ-related SJS/TEN, and HLA-B*58:01 with allopurinol-related SJS/TEN (Hung et al., 2005b). Here, HLA-B is linked to toxic epidermal necrolysis.
