A newly discovered Alzheimer’s gene may drive the first appearance of amyloid plaques in the brain, according to a study led by researchers at Columbia University Irving Medical Center.
Some variants of the gene, RBFOX1, appear to increase the concentration of protein fragments that make up these plaques and may contribute to the breakdown of critical connections between neurons, another early sign of the disease.
The finding could lead to new therapies that prevent Alzheimer’s and better ways of identifying people with the greatest risk of developing the disease.
