A new study conducted at the University of Newcastle, English, revealed the reason for the absence of symptoms in some people who catch the infection with the Corona virus, and they discovered that the secret behind this may be the gene. HLA-DRB1 Responsible for providing a certain level of protection to people, according to a report by time now news The degree to which the coronavirus affects people varies from one individual to another, and there is no doubt that understanding the behavior of the virus in different people helps create the best treatment approach.

Corona symptoms

Common symptoms of corona infection include dry cough Fatigue and fever However, while some people clearly showed symptoms and tested positive for the disease, some people who did not display any of the symptoms listed tested positive.

The gene behind asymptomatic corona cases

According to a study published in the journal HLA Entitled “The effect of the genotype of HLA On the severity of Corona infection , may be the gene HLA-DRB1 Responsible for providing a certain level of protection to people without symptoms of corona.

Dr Carlos Echevarria of Newcastle University’s Institute of Editorial and Clinical Research and co-author of the study said: “This is an important finding because it may explain why some people develop corona without symptoms, which could lead us to a genetic test that may indicate who should prioritize future vaccinations.”

The discovered human leukocyte antigen gene is related to HLA-DRB1 , in latitude and longitude, geolocation also plays a role in this gene, which means that this gene is more likely to be present among people in northern and western Europe..

Study author David Langton said: ‘Some of the most interesting findings were the relationship between latitude and longitude and gene frequency HLA It has long been known that the incidence of multiple sclerosis increases with increasing latitude, thus lowering vitamin D levels. However, we were not aware that one of the major risk genes for MS, which is DRB1 , which is directly related to latitude”.

The study sheds light on the complex interaction between environment, genetics and disease, adding that some genes HLA They respond to vitamin D, and that low levels of vitamin D are a risk factor for coronavirus infection.
