How genetic changes lead to familial Alzheimer's disease

Wednesday, March 11, 2015 - 14:20 in Biology & Nature

Mutations in the presenilin-1 gene are the most common cause of inherited, early-onset forms of Alzheimer's disease. In a new study, scientists replaced the normal mouse presenilin-1 gene with Alzheimer's-causing forms of the human gene to discover how these genetic changes may lead to the disorder. Their surprising results may transform the way scientists design drugs that target these mutations to treat inherited or familial Alzheimer's, a rare form of the disease.
