Unlikely gene variants work together to raise Alzheimer’s risk

Studying spinal fluid from people at risk for Alzheimer’s disease, School of Medicine researchers have found that a gene variation that had not been considered risky actually can increase the chances of developing Alzheimer’s disease when it occurs in tandem with another gene variant known to elevate risk. Shown is an image of a brain with a buildup of amyloid deposits (highest amounts in yellow and red) that collect to form senile plaques in patients with Alzheimer’s.
