ELF5 and COVID-19: Of the 6 refined or suggestive candidates, ELF5 showed significant and directionally consistent associations across all four COVID-19 outcomes included as part of the COVID-19 HGI15, with the strongest effects for more severe outcomes (Fig. 2 and Supplementary Data 5) and strong evidence for a shared genetic signal for outcomes indicating a poorer prognosis (hospitalisation and severe COVID-19; Posterior probability (PP) > 80%).
