HLA-A and toxic epidermal necrolysis: In this study, we analyzed both class I and class II HLA types focused on acetaminophen-related SJS/TEN with SOC and found that there was also no association between HLA class II (HLA-DQB1, DQB1) and acetaminophen-related SJS/TEN with SOC and confirmed the strong association with HLA-A*02:06 and the significant association with HLA-B*44:03, as in our previous study6.
