Study of 2.8 Million People Maps New Alzheimer’s Risk Genes
An international team identified new genetic clues to Alzheimer’s disease in the largest study of its kind so far.
Led by Vrije Universiteit Amsterdam, researchers analyzed genetic data from about 2.8 million people, including 183,620 with Alzheimer’s.
The study linked 127 DNA regions to Alzheimer’s risk, and 48 of those regions had not previously been mapped in this context.
It strengthened evidence that microglia, immune cells in the brain, are involved in the disease.
Genetic signals also pointed to several specific types of neurons, extending the clues beyond the immune system.
Alzheimer’s is the leading cause of dementia, and the findings give researchers more biological processes to investigate.
Further research must test whether these links are causal and whether acting on them could lead to safe, beneficial treatments.
An international study analyzed genetic data from approximately 2.8 million people and identified 127 DNA regions associated with Alzheimer’s risk.
Forty-eight of the regions had not previously been mapped in this context.
The findings point to roles for brain immune cells and specific types of neurons in Alzheimer’s disease.
Researchers say the results provide leads for further study, but do not prove that targeting any gene will produce an effective treatment.
The study was led by Vrije Universiteit Amsterdam and published in Nature.

What people are saying
What makes this study particularly valuable is that we can now connect new genetic risk factors to more specific biological processes, while also uncovering evidence pointing to the involvement of other brain cell types.
This exciting new genetic analysis has uncovered new information on how our genes influence our risk of Alzheimer’s disease.
