About the Central Repository
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. In 2011, the Central Repository staff authored a manuscript "The NIDDK Repository at 8 Years, Ambition, Revision, Use and Impact" which was published in the journal Database. The peer reviewed article documents the use and impact the Repository continues to have on the scientific community.
There are three Repositories:
- Biosample Repository - Fisher BioServices, Inc
(14665 Rothgeb Drive, Rockville, MD 20850; Lab Address: 20301 Century Blvd., Bldg. 6, Suite 400, Germantown, MD 20874)
Receives biosamples collected in many different studies, stores the samples under optimal conditions, and distributes them to qualified investigators. The Contractor for the Biosample Repository is Fisher Bioservices Corporation of Rockville, MD. A complete statement of work for this contract can be found here.
- Genetics Repository - Rutgers, The State University of New Jersey (Rutgers Lab)
(604 Allison Road, Nelson Labs C112, Piscataway, NJ 08854)
Receives blood samples collected in many different studies, and processes them to create immortalized cell lines, and DNA samples. In addition, the Genetics Repository also cryopreserves blood cells, extracts DNA from blood samples, stores samples of DNA under optimal conditions, and distributes DNA samples to qualified investigators. The Contractor for the Genetics Repository is Rutgers, The State University of New Jersey, New Brunswick, NJ. Here is a complete statement of work for this contract can be found here.
- Data Repository - Information Management Services, Inc (IMS)
(3901 Calverton Blvd, Calverton, MD 20705)
Receives, archives, maintains and dirstributes databases from studies. In addition the Data Repository analyzes stored data in response to inquiries, assists ongoing studies in preparing data for eventual archiving, coordinates cross-referencing between the three Repositories, and maintains the Central Repository website. The Contractor for the Data Repository is Information Management Services, Inc, Calverton, MD. A complete statement of work for this contract can be found here.
The NIDDK Central Repository has four major components:
- An archive of clinical data and documentation from NIDDK-sponsored studies
- A collection of biospecimens and an associated database that identifies specimens collected from ongoing and completed studies funded by NIDDK and links them to the associated phenotypic data
- A web portal that contains study-specific information within the Repository and accepts electronic requests for biospecimens and data
- A collection of genotyping data from GWAS and sequencing studies housed at the National Center for Biotechnology Information's (NCBI) database of Genotypes and Phenotypes (dbGaP)

The NIDDK Central Repository development team would like to acknowledge the National Heart, Lung, and Blood Institute and its BioLINCC Program for the programming code used in the implementation of this website. The NIDDK Central Repository code was based on the BioLINCC framework, which shares many of the same advanced features and a well-defined yet flexible workflow for request submission and fulfillment.
