Data Summary
Funded in 2012, NIAGADS became the NIA-designated national data repository to facilitate data sharing for the study of genetics of Alzheimer’s disease and other related dementias (ADRD). 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. See below for information about data hosted in each database (last updated February 2020).

Future Datasets
17K whole-genomes
GCAD is currently processing an additional 13,000 whole-genomes to be joint-called with the first whole-genome dataset, totaling about 17,000 whole-genomes. Joint calling of this dataset will begin in March 2020.
