Sharing of samples and data

All of the samples collected to date are located at the NIDDK Genetic Repository. Researchers that are not part of the Consortium can get access to samples and data via the procedures established by the NIDDK for its Central Repositories—Frequently Asked Questions

NIDDK Central Repositories

On July 1, 2003, The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH) established the Central NIDDK Repositories for biosamples and data collected in clinical studies. The purpose of the Central Repositories is to expand the usefulness of these studies by providing access to the biosamples and data to a wider research community beyond the end of the study.
Data Repository: RTI International. RTI receives, archives, maintains and distributes databases or parts of databases from studies.
DNA and Cell Line Repository: Rutgers, The State University of New Jersey.

Genotype data

A subset of samples have been utilized to complete various genome-wide association studies using dense genotyping arrays. This data will be available at dbGAP.

Ancilllary RO1policy

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) invites investigator-initiated research project applications for ancillary studies to ongoing large-scale clinical trials, epidemiological studies and disease databases supported by the Institute. These studies are focused on a wide range of diseases and conditions including diabetes, obesity, acute and chronic liver disease, chronic kidney disease, benign prostatic hyperplasia, among others. The goal of these ancillary study proposals should be to extend our knowledge of the diseases being studied by the parent study investigators under a defined protocol. The proposed studies may require additional data or sample collection but may not interfere with the primary objectives of the main study. An ancillary study may involve either non-IBDGC or IBDGC investigators and is complementary to ongoing Consortium activities. An ancillary study may use IBDGC study participants or related materials including data sets, biospecimens and genetics samples, but is not a part of ongoing IBDGC activities. Old samples and pre-Consortium samples with phenotype data will be available.

Each applicant must abide by the procedures for conducting ancillary studies established by the parent study group. Investigators wishing to conduct an ancillary study must complete an application to the NIDDK IBD Genetics Consortium. Submission of a completed IBDGC Ancillary Study Proposal form to the Ancillary Studies Committee is required. Proposals should be submitted at least 10 weeks before the anticipated grant application date.
