Protective gene variant against COVID-19 identified
An international metastudy led by researchers at Karolinska Institutet in Sweden has identified a specific gene variant that protects against severe COVID-19 infection. The researchers managed to pinpoint the variant by studying people of different ancestries, a feat they say highlights the importance of conducting clinical trials that include people of diverse descents. The results are published in the journal Nature Genetics.In addition to old age and certain underlying diseases, genetics can influence whether we become severely affected or only suffer mild illness from COVID-19.
