According to the researchers, the carriers of the second group of blood are more vulnerable to coronavirus due particular mutation.
Carriers of the second group of blood are more vulnerable to coronavirus due particular mutations, the researchers found. In the electronic scientific library medRxiv published the preliminary results of the study.
the Team of physicians and molecular biologists under the guidance of Professor Kiel University (Germany), Andre Franke has held the scale at the moment genomic analysis of carriers of the coronavirus. This was decoded the genomes of 1 980 inhabitants in Spain and Italy, caught in seven different hospitals with severe infection.
the Researchers were interested in which factors can help the virus and contribute to complications COVID-19. They compared the sets of mutations in the genes of the subjects among themselves and with how such “typos” in the DNA are common among healthy people of their regions. Scientists have studied how more than 8.5 million variations in the structure of genes influence the probability and character of the course COVID-19.
the First increased the chances of severe disease approximately 1.77 times, while the second increased the probability of infection of 1.32 times. Found that based on the location of mutations within chromosomes, the first was in the SLC6A20 gene, and the second part of the genome that determines the blood type of the person.
the Researchers explain that the SLC6A20 gene directly associated with the receptor ACE2 used by the coronavirus to penetrate into human cells. due similar mutation in the ninth chromosome usually increases blood clotting, which is dangerous for the infected COVID-19.
it is also Noted that this article was not refereed by independent experts and editors of scientific journals, so you should be wary of conclusions from it and similar materials.
Earlier, the head of the Federal biomedical Agency (FMBA) Veronika Skvortsova said that among people infected with coronavirus most patients with the second group of blood.
