CORE C: PROJECT SUMMARY/ABSTRACT The overall goal of the Adjudication and Phenotype Harmonization Core (Core C) is to generate the high quality, analysis ready, clinical diagnoses and harmonized phenotypes. needed to develop the READD-ADSP resource. Developing this resource is in line with NIA's mission to ensure that Alzheimer's disease gene discovery represents all groups including those that have been traditionally underrepresented. Further, the clinical deliverables from Core C will be invaluable to qualified investigators who access the READD-ADSP resource. To produce these clinical deliverables, Core C will adjudicate 13,000 participants (cases/controls) from US sites (n=8,000) and AfDC sites (n=5,000) and harmonize multi-domain phenotype data from the US and African cohorts. The adjudication and harmonization objectives will be accomplished via two aims: (1) Acquisition and processing of clinical data (e.g., data dictionaries and operation manuals) and metadata for adjudication and harmonization; (2) Adjudication and harmonization of clinical data from US and AfDC sites and delivery clinical diagnoses to Core E for distribution to Projects 1 & 2 and both clinical diagnoses and harmonized data to NIAGADS for distribution to the ADSP-Phenotype Harmonization Consortium and the broader scientific community. Ultimately, the value of the READD-ADSP resource resides in its potential to expand understanding of AD genetics in underrepresented groups with implications for therapies that integrate personalized information.
