Abstract

Since the outbreak of COVID-19, genome-wide association studies have tried to discover the role of genetic predisposition in the clinical variability of this viral infection. The findings of various investigations have led to several loci for COVID-19 genetic susceptibility. Among candidate regions, the 3p21.31 locus has been in the spotlight among scientists, as it can increase the risk of severe COVID-19 by almost two fold. In addition to its substantial association with COVID-19 severity, this locus is related to some common diseases, such as diabetes, malignancies, and coronary artery disease. This locus also harbors evolutionary traces of Neanderthal genomes, which is believed to be the underlying reason for its association with COVID-19 severity. Additionally, the inheritance of this locus from Neanderthals seems to be under positive selection. This review aims to summarize a collection of evidence on the 3p21.31 locus and its impact on COVID-19 outcomes by focusing on the risk variants originated from the Neanderthal genome. Moreover, we discuss candidate genes at this locus and the possible mechanisms by which they influence the progression of COVID-19 symptoms. Better insights into human genetic susceptibility to newly emerging diseases such as COVID-19 and its evolutionary origin can provide fundamentals for risk assessment of different populations as well as the development of personalized prevention and treatments based on genomic medicine. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
