Data Repositories

Prechter Bipolar Genetics Repository
The Prechter Bipolar Genetics Repository (PBGR) was established in March of 2007 to give researchers the tools to study and conquer bipolar illness. The Prechter Program's repository is the nation’s largest privately-funded bipolar genetics repository and holds DNA samples from people who have been diagnosed with bipolar disorder as well as healthy individuals.

The University of Michigan is collaborating on this effort with our independently approved partner sites: Johns Hopkins, Penn State, Stanford and Weill Cornell Universities. The investigators have worked to collect phenotypic information, or observable traits, and DNA on thousands of bipolar individuals and control participants. The PBGR also holds additional data and biological material on a subset of these participants, including imaging data, electrophysiology, nutrition, stem cells, sleep, and medication data. The repository data has a richness unlike any other collection of bipolar research data in the world.

The PBGR is a vitally important tool to rapidly accelerate genetic research, one of the most significant areas of study today.

University of Michigan Medical School Central Biorepository (CBR)
In January 2016, the Prechter Longitudinal Study of Bipolar Disorder began to store biospecimens in the world-class, UMMS Central Biorepository. The Central Biorepository provides a standardized and accredited system to safely process, store and distribute biospecimens, along with associated clinical data, that have been donated for research. The quality and accessibility of these samples and the accompanying data will enhance and inform basic, clinical and translation research in bipolar disorder in this country and across the globe.

TamNet Data Repository
The TamNet Data Repository was established by the Prechter Bipolar Research Program in October, 2016 to safely store, process and distribute mobile or electronically-captured health information, including de-identified speech data. This repository is a vital component of the Prechter Program’s mobile health research project, PRIORI, which is currently being used in multiple studies at the University of Michigan and collaborating institutions.
