COVID-19 infections are also affected by human ACE1 D/I polymorphism

The number of victims of the COVID-19 pandemic shows important geographical differences. In this study, a number of human genetic polymorphisms were compared to the number of Covid-19 patients and Covid-19 mortality. Data from 33 countries were analyzed. Among the polymorphisms tested, the human angiotensine converting enzyme (ACE) polymorphism turned out to be a determinant factor in both prevalence and mortality. The present findings may partly explain why some countries are more affected than others by the Covid-19 pandemic.
