HLA-DRB1 and infection: Remarkably, the alleles HLA-B*51:01, HLA-C*06:02, HLA-C*07:01, HLA-C*12:03, and HLA-DRB1*11:04 were associated with protection against SARS-CoV-2 infection, while the alleles HLA-B*08:01, HLA-B*44:03, DRB1*11:01, DRB1*11:04, DRB1*13:01, DRB1*15:01, DQB1*06:03, and DQB1*06:02 were associated with susceptibility to infection with SARS CoV-2 [59].
