Researchers are studying the genetic architecture of host proteins involved in SARS-CoV-2 infection, exploring the interplay between host genetics and covid-19. The role of various genetic processes, including glycosylation and chromatin architecture, is being investigated in relation to susceptibility to SARS-CoV-2 infections and covid-19 outcomes. Studies are identifying specific host proteins and genetic variants associated with strong antibody responses and potential risk for covid-19.
