Scientists have been looking at genetic factors to try to determine why some people who contract with the new CORONAVIRUS experience no symptoms, while other become gravely I’ll.
In April, 23 and Me launched a study that sought to use the millions of profiles in its DNA database to shed light on the genetic role play in the disease.
Preliminary results from more than 7,50,000 participants suggests that the O blood group is especially protective against SARS-COV-2, the virus that causes COVID-19.
The researchers found that individuals with type O blood are between 9% and 18% less likely than individuals with other blood types to have tested positive for COVID-19.
Studying the genetics of the people who are more susceptible to SARS-COV-2 could help to identify and protect those more at risk ,as well as help speed treatment and drug development.
Several other studies looking at both severity of illness and susceptibility to disease have also suggested blood type plays a role.
The 23 and Me study ,which looked at suspectibility rather, than severity of illness, included 10,000 participants who told the company they had COVID-19.
It’s early day’s , even with these sample sizes, it might not be enough to find genetic associa6,he said. ” we are not the only group looking at this, and ultimately the scientific community may need to pool their resources to really address questions surrounding the links between genetic and COVID-19 .” – Bloombery
Another study conducted by a group of INTERNATIONAL RESEARCHERS IN GERMANY said the pateints with blood group A+ are more likely to need oxygen support and suffer serious illness if they contract the COVID-19.
“Association signal at 9q34 was located at the ABO blood group locus and a blood group specific analysis showed higher risk for A- positive individually and a protective effect for blood group O” , the study results started.
