Three genetic modifiers may alter inherited Alzheimer's onset and progression

Autosomal dominant Alzheimer's disease (ADAD) is a genetically inherited form of Alzheimer's disease that accounts for only about 1% of Alzheimer's disease cases.

However, because individuals with the gene mutations are extremely likely to develop Alzheimer's disease at an early age, and because the mutation is highly heritable, ADAD is widely studied by Alzheimer's disease researchers. ...
