Gene that raises risk of Covid-19 affects many of South Asian ancestry


About 60% of people with South Asian ancestry carry the high-risk gene, according to researchers at Oxford University. The discovery partly explains the high number of deaths seen in some British communities, and the effect of Covid-19 in the Indian sub-continent, reported Reuters (5 Nov 2021). The scientists found that the increased risk is not because of a difference in genetic coding of the proteins, but because of differences in the DNA that makes a kind of “switch” to turn a gene on.
