Some genetic risk factors for alcohol use disorder overlap with those for neurodegenerative diseases like Alzheimer’s, scientists reported in Nature Communications on August 20. The study, which relied on a combination of genetic, transcriptomic, and epigenetic data, also offers insight into the molecular commonalities among these disorders, and their connections to immune disfunction.

“By meshing findings from genome wide association studies . . . with gene expression in brain and other tissues, this new study has prioritized genes likely to harbor regulatory variants influencing risk of Alcohol Use Disorder,” writes David Goldman, a neurogenetics researcher at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), in an email to The Scientist. “Several of these genes are also associated ...
