Alzheimer’s study links 127 DNA regions to risk across analyses, including 48 classified as new

Researchers writing in Nature identified 127 regions of DNA associated with Alzheimer’s risk across their analyses, including 48 they classified as new. The study drew on data from about 2.8 million people, some counted through reports of a parent’s condition. Its cell analyses found a stronger signal in microglia than in specific neuronal subtypes. The findings point to future research, not a treatment.
