Three different groups conducted association analyses against a healthy control group to identify susceptibility of infection to SARS-CoV-2: Wang et al. (2020b) compared 82 COVID-19 vs 3,548 controls from China and found HLA-B*15:27 as associated (p-value = 0.001, OR 3.6), Novelli et al. (2020) compared 99 COVID-19 vs 1,017 controls from Italy and found 3 significant association (HLA-B*27:07, p-value = 0.00001; HLA-DRB1*15:01, p-value = 0.002; HLA-DQB1*06:02, p-value = 0.0001), and Yung et al. (2020) compared 190 COVID-19 vs 3892. This evidence concerns the gene HLA-B and COVID-19.
