Two international teams of researchers, with NIH scientists and support, have separately identified a rare variation in the TREM2 gene as a moderate risk factor for late-onset Alzheimer’s disease. TREM2 is a gene involved in inflammation and immune response, and this discovery provides an important clue for researchers seeking a better understanding of the Alzheimer’s disease process. Researchers have hypothesized for many years that a rare genetic variant can confer moderate risk for disease. These are the first studies to identify such a variant related to Alzheimer’s disease.
