CBZ‐induced SJS/TEN is strongly associated with HLA‐B*15:02 in Han Chinese, Thais, and Malays,6 whereas HLA‐A*24:02 has also recently been identified as a risk factor in Han Chinese.7HLA‐A*31:01 is associated with a variety of CBZ‐SCAR phenotypes and maculopapular exanthema in Japanese,8 Korean,9 and European‐descent populations.10 Several other HLA loci have been suggested as susceptibility loci, including HLA‐A*02:06,8HLA‐B*15:11,11 and HLA‐B*51:01,12, 13, 14 but the findings have not always been replicated.15 Currently, we have limited knowledge of susceptibility loci for CBZ‐DILI. The gene discussed is HLA-B; the disease is Schwartz-Jampel syndrome.
