Further, G protein subunit alpha 15 (GNA15), one of the 11 genes discerned here, is associated with G-protein signalling and has enhanced expression in immune cells according to The Human Protein Atlas (http://www.proteinatlas.org, last accessed on 1 August 2021) [40] and therefore might play a role in the progression of COVID-19. This evidence concerns the gene GNA15 and COVID-19.
