NIAGADS, along with a number of NIH initiatives, ensures that genotypic data for the study of Alzheimer’s disease and related dementias (ADRD) is harmonized and shared with the research community at large. The centers and projects listed here work together on data collection and curation from start to finish – through sequencing, processing, storing, and sharing. These collaborations, along with an upcoming machine learning initiative, allow for capacity building and enhanced discovery in the field of ADRD genetics.
