Funded in 2012, NIAGADS became the NIA-designated national data repository to facilitate data sharing for the study of the genetics of Alzheimer’s disease and other related dementias (ADRD). NIAGADS is the data coordinating center for ADSP, responsible for collecting phenotypes and consent definitions from 53 ADSP cohorts (26 consent levels consolidated from 58 different definitions/135 institution IRBs), preparing all of the files for release, and coordinating data access by facilitating ADSP analysis workgroups. The NIAGADS Data Sharing Service (DSS) was developed in 2018 to host and share data generated from the Alzheimer’s Disease Sequencing Project (ADSP) with the research community. Qualified investigators can submit Data Access Requests (DARs) through the DAR Management (DARM) system to be reviewed by a Data Access Committee made up of NIH officials and independent UPenn representatives. NIAGADS has processed 374 DARs and renewals since ADSP started in 2012.
