ICAM1 and COVID-19: ICAM1 showed strong effect on COVID-19 severity in Europeans (OR=1.113, 95%CI=1.075 to 1.152, P = 1.5 × 10−9) and a suggestive effect in Africans (OR=1.275, 95%CI=1.031 to 1.575, P = 0.025) using GenOMICC v2 data, with little evidence of heterogeneity of the effect estimates across ancestries (P of pair-wise Z-score test=0.215; Table S8E).
