The HLA-A*24:02 allele was also involved in a study on bronchoalveolar lavage fluid and blood samples of COVID-19 patients [78], while the HLA-A*11:01 allele, together with the HLA-A*02:06 and HLA-B*54:01 alleles, could protect against infection [79]. This evidence concerns the gene HLA-B and COVID-19.
