A crucial role of ACE2 has been suggested in the development of lung injury in the context of the SARS‐CoV outbreak of 2003 (Kuba et al., 2005), and the use of recombinant ACE2 (rACE2) protein has been reported to have a protective effect on ARDS in animal models (Zou et al., 2014). The gene discussed is ACE2; the disease is acute respiratory distress syndrome.
