Abstract

The ongoing pandemic of COVID-19 has elaborated an idiosyncratic pattern of SARS-CoV-2-induced symptoms in the human host. Some populations have succumbed to the SARS-CoV-2 infection in large numbers during this pandemic, whereas others have shown a resilient side by manifesting only milder or no symptoms at all. This observation has relayed the onus of the heterogeneous pattern of SARS-CoV-2-induced critical illness among different populations to the host genetic factors. Here, the evolutionary route was explored and three genetic loci, i.e., rs10735079, rs2109069, and rs2236757, associated with COVID-19 were analyzed. Among the three, the risk allele A at genetic locus rs2236757 residing in the gene was observed to have undergone recent positive selection in the African population.

摘要

持续的新冠疫情展现了新冠病毒在人类宿主中引发症状的独特模式。在此次疫情期间,一些人群大量感染新冠病毒,而另一些人则表现出抵抗力,仅出现较轻微症状或完全无症状。这一观察结果将不同人群中新冠病毒引发重症的异质性模式的责任归咎于宿主遗传因素。在此,探索了进化途径,并分析了与新冠病毒相关的三个基因位点,即rs10735079、rs2109069和rs2236757。在这三个位点中,位于 基因的rs2236757基因位点的风险等位基因A在非洲人群中经历了近期的正选择。
