A genetic variant that raises one’s risk of developing Alzheimer’s disease may also make people more susceptible to COVID-19.  People with two copies of a version of the APOE gene called APOE4 are 14 times as likely to develop Alzheimer’s disease as people with two copies of the APOE3 version of the gene (SN: 9/22/17). Those people were also more than twice as likely to test positive for the coronavirus than people with two copies of the APOE3 version, researchers report May 26 in the Journals of Gerontology: Series A. The results come from a study of more than 600 people in England diagnosed with COVID-19 from March 16 to April 26. Two previous studies showed that people with dementia were more likely to have severe cases or to die of COVID-19. This new study found that even people with no signs of dementia or other diseases associated with having APOE4 were still more susceptible to COVID-19 than people with the APOE3 version.  Sign up for...
