In this study, the occurrence frequency of HLA-A*11:01, B*46:01, B*13:01, C*01:02, C*03:04, C*06:02, DRB1*04:05, DRB1*12:01, DRB1*16:02, DQB1*03:01, DQB1*03:03, and DQB1*04:01 in COVID-19 patients were higher than in Chinese population (19), but its significance needs to be verified in a larger sample. Here, HLA-A is linked to COVID-19.
