On Jul. 15, 2020, A new Cleveland Clinic study identified genetic factors that may influence susceptibility to COVID-19. Published in BMC Medicine, the study findings could guide personalized treatment for COVID-19.

Looking at 81,000 human genomes from three genomic databases, researchers found 437 genetic variants in the protein-coding regions of ACE2 and TMPRSS2. They identified multiple polymorphisms in both genes that offer potential explanations for different genetic susceptibility to COVID-19 as well as for risk factors.
