Genomic epidemiology of acute respiratory distress syndrome and fibrosis in patients with COVID-19

COVID-19 is an infectious respiratory disease with a global devastating health impact. Genetic and environmental factors influence COVID-19 susceptibility and outcomes, including the development of acute respiratory distress syndrome (ARDS) and pulmonary fibrosis. These lung pathologies have a high mortality and there are no specific treatment options or effective prognostic methods for patients. Therefore, there is an urgent need to identify effective biomarkers of disease prognosis. The aim of this research is to perform a genomic epidemiology study of ARDS and pulmonary fibrosis in patients with COVID-19. For that purpose, we will perform genetic overlap studies that will include genetic correlation analyses, polygenic risk score approaches, and assessments of overlap of individual genetic variants, followed by fine mapping studies, bioinformatic approaches to identify the likely causal genes, and further experiments to evaluate their role in disease and their potential as drug targets. Results of these analyses will allow us to identify novel genetic risk factors and to develop risk prediction models, which could enhance COVID-19 patient stratification for those at increased risk of lung sequela. Furthermore, the project will reveal novel therapeutic strategies, which would translate into improved and more personalised clinical care for patients at risk of lung fibrosis.
