In terms of immunity, expression changes in CD151, PIDD1, and DPP9—genes involved in immune cell activation and NF-kB-mediated immune response (Okondo et al., 2017; Rocha-Perugini et al., 2014; Tinel et al., 2007)—were associated with two distinct COVID-19 hg-replicated SNPs (rs3934992, rs12610495). Here, PIDD1 is linked to COVID-19.
