Genome-wide association studies (GWAS) are used to identify common genetic factors that influence health and disease. In January 2008, the NIH implemented a policy for the sharing of data obtained in NIH-supported or conducted GWAS. The purpose of the policy is to foster science for the benefit of the public through the creation of a centralized NIH GWAS data repository. This Website supports the GWAS policy's implementation.

The NIH will continue to release additional information about the NIH GWAS policy on this site. Please e-mail questions about the policy to GWAS@mail.nih.gov.

NIH has implemented a new process for accessing certain aggregate datasets designated as general research use (GRU) through a single request for the Compilation of Aggregate Genomic Data study. These data will continue to remain in controlled access with all the same expectations as other controlled-access data, including data management practices and annual reporting on data use.
