In this study, HLA class II alleles (HLA-DPA1*01:03/DPB1*02:01, HLA-DPA1*02:01/DPB1*01:01, HLA-DPA1*02:01/DPB1*05:01, HLA-DPA1*02:01/DPB1*05:01, HLA-DPA1*02:01/DPB1*14:01, HLA-DQA1*01:02/DQB1*06:02, HLA-DRB1*04:01, HLA-DRB1*04:05, HLA-DRB1*07:01, and HLA-DRB1*15:01) that can be associated with post-COVID-19 autoimmunity were predicted based on bioinformatics analysis. The gene discussed is HLA-DQA1; the disease is Autoimmunity.
