Polygenic quantitative traits for Alzheimer and Related Pathologies Lead Investigator: Corey McMillan Institution : University of Pennsylvania E-Mail : mcmillac@pennmedicine.upenn.edu Proposal ID : 1504 Proposal Description: The goal of this project is to relate previous meta-statistics derived from neuropathology and other association studies to tau, amyloid, Lewy body, and TDP-43 pathological load. We then plan to cluster individuals based on several polygenic scores to identify genetic subgroups for those at risk for PART, AD, LATE and related disorders.
