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).
