Research on Sars-CoV pathogenesis which might be very similar to Sars-CoV-2 pathogenesis has focused the discussion on ACE inhibitors, recombinant ACE2, and ARBs and how they could fit in the pathogenesis of COVID-19, since these pathways were extensively studied in SARS (Fang et al., 2020; Batlle et al., 2020). The gene discussed is ACE2; the disease is severe acute respiratory syndrome.
