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).

NIAGADS DSS Data Summary

Data Numbers

The ADSP has released whole-genomes for 4,750 subjects which include CRAMs, gVCFs, a quality-controlled project level VCF, and phenotypes as well as whole exomes for 19,705 subjects including CRAMs, gVCFs, and phenotypes. These data are available for qualified researchers to access. More information can be found on the ADSP Umbrella dataset page.

Sample Composition

NIAGADS DSS is currently hosting 4,789 whole genomes and 19,922 whole exomes from the ADSP and other AD and Related Dementia’s studies. A breakdown by affection status and Ethnicity is shown here.

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.
