One of the main unanswered questions is why some individuals infected with COVID-19 develop severe disease, whilst others do not. Current evidence suggests that genetic variations influence human immune reactions to microbial infections, including both innate and adaptive immune responses. Here, we aim to evaluate the impact of genetic factors on the variability of the innate immune response to SARS-CoV-2 infection. On top of a large screening of the classical immune response genes (e.g. IFNs, ILs, TLRs, MHCs), we are particularly interested in the IRG1/ACOD1 gene, which we previously di...
