Kind: research · Impact: medium

## In brief

- An international genetic study of more than 2.8 million people identified 127 regions of human DNA associated with Alzheimer's disease.
- 48 of the 127 regions had not previously been linked to the condition.
- The research, published in Nature, indicates that common inherited variants contribute more to Alzheimer's risk than previously thought.

## Why it matters

The findings expand the known genetic map of Alzheimer's risk, which can guide future research into biological pathways and potential drug targets.
