Summary:

- The article discusses a new study that has identified a potential genetic driver of Alzheimer's disease. Researchers have discovered a rare genetic variant that appears to increase the risk of developing Alzheimer's by up to 75%.
- The study, published in the journal Nature Genetics, involved analyzing the genomes of over 111,000 people, including those with and without Alzheimer's disease. The researchers found that a specific variant of the TREM2 gene was more common in individuals with Alzheimer's.
- This finding could lead to new avenues for Alzheimer's research and potentially pave the way for the development of targeted therapies. The researchers emphasize the need for further studies to fully understand the role of this genetic variant in the development of the disease.
