Scientists use shared genome data to confirm SORL1 gene linked to Alzheimer's
October 29, 2007
Until recently, only one of the approximately 30,000 genes in the human genome has been linked to risk of late-onset Alzheimer’s disease (AD). Now, a new NIH-supported study in the Nov. 19, 2007, issue of NeuroReport (now online) used a...
