IFNAR2 and COVID-19: Comforting these results, a recent study detected, validated and replicated the association between COVID-19 severity (i.e., admission to critical care) and rs2236757 (chr21q22.1) in the interferon receptor gene IFNAR2 and rs10735079 in the gene cluster coding for interferon-inducible 2’-5’-Oligoadenylate Synthetase (OAS) 1, 2, and 3 (chr12q24.13) comparing severe COVID-19 patients with controls from the population [117] (Table 3).
