Administrative and Enrollment Core (Core A) Abstract The Administrative and Enrollment Core (Core A) is mandated by the PAR and will oversee, facilitate and coordinate all ACAD activities carried out by other Cores and Projects. Using a robust administrative structure, the Core directs the ACAD’s activities to ensure maximal coordination and produce cutting-edge science to support the ACAD project. Core A will identify relevant ADRD data sets (ADGC, ADSP and non-ADSP data), and coordinate acquisition, processing, and harmonization of these data with the Data Management and Analysis Core (Core D) and Projects. Data will include: 1) genetic data (GWAS SNP array data), 2) biomarker and functional genomics (FG) data, and 3) phenotype data from ACAD participants and other non-ACAD datasets. Core A will coordinate transfer of ACAD data and analysis results to National Institute on Aging Genetics of Alzheimer’s Disease Storage site (NIAGADS) for sharing with the general scientific community.
