TMPRSS2 and COVID-19: The differential genetic susceptibility to COVID-19 as well as for risk factors, including those with cancer, may be explained at least in part by unique but prevalent polymorphisms, including p.Val160Met (rs12329760), an expression quantitative trait locus (eQTL) in TMPRSS2. The likely adverse effect of the rs12329760 polymorphism in the coding region of the TMPRSS2 gene was corroborated by a recent study that used data of the 1000 Genome Project and web-based tools [51].
