Gene variation common in South Asians found to double risk of dying from COVID

Scientists identified a specific gene that doubles the risk of respiratory failure from Covid-19 and may go some way to explaining why some ethnic groups are more susceptible to severe disease than others. Researchers from the University of Oxford found that a higher-risk version of the gene most likely prevents the cells lining airways and the lungs from responding to the virus properly. About 60% of people with South Asian ancestry carry this version of the gene, compared with 15% of people with European heritage, according to the study published [November 4]. The findings help explain why higher rates of…
