The National Institute on Aging Genetics of Alzheimer's Disease Data Storage Site

NIAGADS is a collaborative agreement between the National Institute on Aging and the University of Pennsylvania that stores and distributes genetics and genomics data from studies on Alzheimer’s disease, related dementias, and aging to qualified researchers globally.

Qualified Access

The NIAGADS Data Sharing Service (DSS) is home to genetics and genomics data from the Alzheimer’s Disease Sequencing project and many other datasets that require qualified access for distribution.

Open Access

In addition to qualified access data housed in the DSS, NIAGADS freely offers any ADRD data we can through our publicly available files portal and annotation resources.
