Specifically, LAG3 (IVW, 3 SNPs, p = 0.0069) was found to be a risk factor along with the most notable SNP (rs67706382, p = 6.16 × 10−16), but SLFN5 (IVW, 3 SNPs, p = 0.0012) with the most notable SNP (rs67706382, p = 6.16 × 10−16) was a protective factor against COVID-19 (Figure 5B). The gene discussed is LAG3; the disease is COVID-19.
