An anti-viral gene that impacts the risk of both Alzheimer’s disease and severe Covid-19 has been identified by a UCL-led research team.
The researchers estimate that one genetic variant of the OAS1 gene increases the risk of Alzheimer’s disease by about 3-6% in the population as a whole, while related variants on the same gene increase the likelihood of severe Covid-19 outcomes.
The findings, published in Brain, could open the door for new targets for drug development or tracking disease progression in either disease, and suggest that treatments developed could be used for both conditions. The findings also have potential benefits for other related infectious conditions and dementias.
