In 2003, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at NIH established Data, Biosample, and Genetic Repositories to increase the impact of current and previously funded NIDDK studies by making their data and biospecimens available to the broader scientific community. These Repositories enable scientists not involved in the original study to test new hypotheses without any new data or biospecimen collection, and they provide the opportunity to pool data across several studies to increase the power of statistical analyses. In addition, most NIDDK-funded studies are collecting genetic biospecimens and carrying out high-throughput genotyping making it possible for other scientists to use Repository resources to match genotypes to phenotypes and to perform informative genetic analyses.
45 studies available for request and 49 ongoing studies being tracked or curated. There are more than 40 sample types with over 6 million biospecimens from 94 studies/networks stored in the sample repositories
The NIDDK Central Repositories are three separate contract-funded components that work together to store data and samples from significant, NIDDK-funded studies. More Information regarding each repository is available at: https://www.niddkrepository.org/pages/about/
