Genetic link discovered in loss of smell from COVID-19, scientist says

23andMe researchers surveyed 1.3 million customers to get their data ATLANTA — Over the last 15 months, scientists at 23andMe have been researching why COVID-19 affects people so differently and why some get certain symptoms -- like the loss of smell. Genetics could play a part in the answer. Dr. Janie Shelton, a senior scientist and epidemiologist at 23andMe, said they started genetic research into symptoms, like anosmia (loss of smell), back in March 2020. "About 68 percent of the population who's tested positive has reported losing their sense of smell or taste," Shelton said. They have discovered a genetic link into why some people lose their sense of smell from COVID and others do not. To get their data they sent surveys out through their app to customers across the U.S. More than 1.3 million responded - 80,000 of whom had experienced COVID-19. Since these were all 23andMe customers, the scientists already had their genetic background in their system. "We ran one of these genome association studies on people who had lost her smell compared to people who did …
