ACE2 and infection: We can conclude that genetic susceptibility to infection with SARS-CoV-2 mainly involves ACE2 and TMPRSS2. Torre-Fuentes et al. [6], Hussain et al. [11], Gomez et al. [9], Wang et al. [12], Fujikura et al. [15], Yamamoto et al. [16], Sienko et al. [17], Paniri et al. [18], Nguyen et al. [10], Senapati et al. [19], Novelli et al. [20], Vargas-Alarcon et al. [21], Benetti et al. [22], Strafella et al. [13], Shikov et al. [23], Srivastava et al. [14], and Kim et al. [24] mention ACE2 as SARS-CoV-2 susceptibility related gene.
