Furthermore, a number of variants in HLA alleles/haplotypes are known to be associated with susceptibility and progression of various infections, including SCOV2, with some of the most indicative summarized in (107), namely: HLA-A*11:01/24:02 with protective role against SCOV2 infection; HLA‐A*24:02 and HLA-B*22 with SCOV2 infection susceptibility; HLA-A*25:01 with moderate disease outcomes; and HLA-A*01:01/02:01, HLA-B*15:03/27:07, HLA-C*05 and HLA-E*01:01 with severe outcomes. The gene discussed is HLA-E; the disease is infection.
