has found that a group of genes,
dubbed Neanderthal covid genes,
reduce the risk of developing severe Covid-19
by around 20%
and have been inherited from Neanderthals.

Now a new research project in Japan has identified a group of three genes in human DNA, inherited from Neanderthals, that assist the body's cells while attempting to defeat invading viruses.
These genes can reduce the risk of developing severe Covid-19 "by around 20%"...
The scientists have now determined that having this gene can help you fight SARS-CoV-2, which impacts people in different ways ranging from no symptoms at all to respiratory failure and death...
Now, the same group of genes has been found to be beneficial to around 20% of people and it can help reduce their risk of becoming seriously ill and being hospitalized with Covid-19.
This new research (A Genomic Region associated with Protection against severe COVID-19 is Inherited from Neandertals) has just been published in PNAS...
The recent research shows that the
gene dubbed the "Neanderthal Covid gene"
can impact our ability to develop
severe Covid-19 symptoms.

22% Lower Risk of Severe Covid-19 Symptoms
The same pair of scientists have now published a new study based on the findings of a 2020 study by Genetics of Mortality in Critical Care (GenOMICC).
This UK based project analyzed the genome sequences of "2,244 people who developed severe COvid-19" and they identified additional genetic regions on four chromosomes that impact how individuals respond to the virus when they become infected.
The research shows human genes,
However, "surprisingly," this second genetic factor influences Covid-19 outcomes in the opposite direction to the first genetic factor,
For those who like to keep abreast of developments in DNA sciences, this Neanderthal variant was discovered on chromosome 12.
And to be accurate,

How Neanderthal Genetic Variants Affect Us Today
Attempting to understand how this Neolithic genetic variant affects Covid-19 outcomes, the research team looked at three genes located in a newly identified region.
In an Okinawa Institute of Science and Technology (OIST) Graduate University press release Professor Pääbo explained that,
In their new study the researchers also analyzed how the newly discovered Neanderthal-like genetic variants,
Professor Pääbo commented that the enzymes encoded by the Neanderthal variant,
Furthermore, the results of the new study show the Neanderthal variant,
Bad Neanderthal Gene Is Not a Japanese "Thing" at All
The fact that the Neanderthals had developed this gene over 60,000-years-ago suggested to the researchers that it must have been beneficial also in the past,
Returning for a moment to last year's paper which identified a Neanderthal gene that posed "a major health risk" (sic...)
The Japanese scientists must have been somewhat relieved to discover in their new study that this negative genetic variant inherited from Neanderthals, is almost non-measurable in modern Japanese populations...
