A team of researchers at genomics and biotechnology company 23andMe have found that people with a certain genetic locus are 11% more likely to lose the ability to smell or taste due to a COVID-19 infection. In their paper published in the journal Nature Genetics, the group describes studying the genomes of 70,000 adults from the U.S. and the U.K., looking for genes associated with taste and smell loss during COVID-19 infections.
