This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Pulmonary inflammation drives critical illness in Covid-19, creating a clinically homogeneous extreme phenotype, which we have previously shown to be highly efficient for discovery of genetic associations. Despite the advanced stage of illness, we have found that immunomodulatory therapies have strong beneficial effects in this group. Further genetic discoveries may identify additional therapeutic targets to modulate severe disease. In this new data release from the GenOMICC (Genetics Of Mortality in Critical Care) study we include new microarray genotyping data from additional critically-ill cases in the UK and Brazil, together with cohorts of severe Covid-19 from the ISARIC4C and SCOURGE studies, and meta-analysis with previously-reported data. We find an additional \numconvincingnew new genetic associations. Many are in potentially druggable targets, in inflammatory signalling (JAK1, PDE4A), monocyte-macrophage differentiation (CSF2), immunometabolism (SLC2A5, AK5), and host factors required for viral entry and replication (TMPRSS2, RAB2A). As with our previous work, these results provide tractable therapeutic targets for modulation of harmful host-mediated inflammation in Covid-19.
