CSF1 and COVID-19: Using the cis-pQTL instrument definition and considering a false discovery rate (FDR) < 5%, genetically proxied concentrations of macrophage colony stimulating factor (MCSF) were inversely associated with the risks of SARS-CoV-2 infection and hospitalization due to COVID-19 (odds ratio [OR]: 0.94, 95% confidence interval [CI]: 0.91 to 0.97, p (not FDR corrected) = 1.0 × 10−4 and OR: 0.90, 95%CI: 0.84 to 0.96, p = 1.4 × 10−3, respectively).
