GNB3 and COVID-19: We found that a younger patient age (<62 years; p < 0.0001), erythrocyte (≥4.0/nl; p = 0.02), platelet (≥133.5/nl; p < 0.0001), neutrophil (<6.6/nl; p < 0.0001), and lymphocyte (≥0.9/nl; p < 0.0001) counts above these respective thresholds at the time of admission to hospital, and the GNB3 rs5443 TT genotype (p = 0.03) remained independent predictors for protection against COVID-19 fatality (Table 3).
