ELF5 and COVID-19: We prioritised ELF5 as the causal gene at this locus through a cluster of colocalising phenotypes, including three different COVID-19 outcomes, ELF5 expression in the lung, and ELF5 abundances in plasma (PP = 93% for a shared signal across all outcomes), with rs766826 being the most likely (PP = 99%) underlying causal variant (Fig. 3).
