In the study, there was only one ampicillin/sulbactam-induced SJS patient who carried HLA-A*11:01/24:02, HLA-B*18:01/52:01, HLA-C*05:01/12:02, and HLA-DRB1*04:03/04:84 alleles and one meropenem-induced DRESS patient who carried HLA-A*24:02/74:01, HLA-B*15:02/15:02, HLA-C*08:01/08:01, and HLA-DRB1*12:02/14:22 alleles (Singvijarn et al., 2019). Here, HLA-B is linked to Schwartz-Jampel syndrome.
