COVID-19: impact on Public Health and hypothesis-driven investigations on genetic susceptibility and severity

Immunogenetics. 2022 Aug;74(4):381-407. doi: 10.1007/s00251-022-01261-w. Epub 2022 Mar 29.

Abstract

COVID-19 is a new complex multisystem disease caused by the novel coronavirus SARS-CoV-2. In slightly over 2 years, it infected nearly 500 million and killed 6 million human beings worldwide, causing an unprecedented coronavirus pandemic. Currently, the international scientific community is engaged in elucidating the molecular mechanisms of the pathophysiology of SARS-CoV-2 infection as a basis of scientific developments for the future control of COVID-19. Global exome and genome analysis efforts work to define the human genetics of protective immunity to SARS-CoV-2 infection. Here, we review the current knowledge regarding the SARS-CoV-2 infection, the implications of COVID-19 to Public Health and discuss genotype to phenotype association approaches that could be exploited through the selection of candidate genes to identify the genetic determinants of severe COVID-19.

Keywords: COVID-19; Candidate gene association studies (CGAS); Genetic determinants of severe disease; Genetic susceptibility to infection; Genome-wide association studies (GWAS); Public Health.
