Until now the reason why there are many people with
coronavirus
who are asymptomatic remained one of the big questions about
Covid-19
.
Now, British researchers have found the gene that explains why many people who become infected with the
coronavirus have
no symptoms.
It is the
HLA-DRB1 * 04: 01
gene
.

They discover the gene that makes many people with coronavirus asymptomatic
Researchers at the University of Newcastle (United Kingdom) have discovered that the
HLA-DRB1 * 04: 01 gene
is responsible for many people who become infected with the
coronavirus
do not have symptoms and, if they do, they are mild.
This is the first clear evidence of
genetic resistance
as this study, published in the journal
HLA
, compared severely affected people to a group of
asymptomatic
Covid-19
and used next-generation sequencing to focus on
genes
in detail and at
scale. HLA
that are clustered on chromosome 6.
Genome-wide studies can be compared to a satellite image, although the high density and complexity of the histocompatibility complex and the variation in different populations means that significant variation can be missed.
The identified human leukocyte antigen gene,
HLA-DRB1 * 04: 01
, is known to be directly related to latitude and longitude, meaning that more people in northern and western Europe are likely to have this gene and that therefore, populations of European descent will be more likely to remain asymptomatic.
