GENE VARIANT FROM NEANDERTHALS DECREASES SEVERE COVID-19 RISK

Half of all people outside Africa carry a gene variant inherited from Neanderthals that reduces the risk of needing intensive care for Covid-19 by 20 per cent, says a new study.According to the scientists, this variant, which reduces the risk of needing intensive care upon infection with the virus by 20 percent, is inherited from Neanderthals.

The genes, called OAS, regulate the activity of a protein that breaks down viral genomes, and the study noted that the Neanderthal variant of this protein does this more efficiently.The study also shows that the protective variant from Neanderthals has increased in frequency since the last Ice Age so that it is now carried by about half of all people outside Africa.
