Lee et al. (2016) reviewed several cases in Singapore and found the association between HLA-A*33:03 as well as HLA-B*58:01 and SR-induced SJS/TEN in Chinese population. Recently, Chen et al. (2021b) demonstrated that there is an association between HLA-A*33:03 and SR-induced SJS in Taiwanese population. Here, HLA-A is linked to toxic epidermal necrolysis.
