OAS1 and COVID-19: The genetically-predicted protein levels of OAS1 (OR=0.440, 95%CI=0.315 to 0.615, P = 1.57 × 10−6), FCRL3 (OR=1.032, 95%CI=1.030 to 1.034, P = 2.40 × 10−191) and ICAM5 (OR=0.780, 95%CI=0.691 to 0.880, P = 5.74 × 10−6) showed MR association with COVID-19 severity (Table S8B) using data from GENOMICC.
