TWAS-based translational genomics approach identifies IL10RB as the top candidate gene for COVID-19 host susceptibility and severity

ABSTRACT: Recent efforts have identified genetic loci that are associated with coronavirus disease 2019 (COVID-19) infection rates and disease outcome severity. Translating these genetic findings into druggable genes that regulate COVID-19 host susceptibility is a critical next step. Using a translational genomics approach that integrates COVID-19 genetic susceptibility variants, multi-tissue genetically regulated gene expression (GReX) and perturbagen signatures, we identify IL10RB as the top key regulator of COVID-19 host susceptibility. In a series of validation steps we show that predicted GReX up-regulation of IL10RB and higher IL10RB expression in COVID-19 patient blood is associated with worse COVID-19 outcomes, and that in vitro IL10RB overexpression is associated with increased viral load and activation of disease-relevant molecular pathways.
