There are currently over 9000 participants enrolled, with an ultimate goal of 50,000 participants. This registry includes self-reported information, baseline biospecimens, annual follow-up, access to electronic health records, and permission to re-contact.

The Study comprises a series of stages or “horizons”. Horizon 1 involved the generation and analysis of omics data in four existing disease cohorts. Horizon 1.5 is a community-based registry and biorepository. Horizon 2 leverages the Horizon 1.5 registry for validation studies and recruitment of target populations, and Horizon 3 expands the scope of the study to include populations from around the region and the world. Genomic, transcriptomic, metabol-omic, and/ or proteomic data has been generated for a number of disease-focused cohorts, and data collection is ongoing for additional disease areas and healthy controls from a 50,000 person community-based registry (9000 enrolled to date). This valuable data resource is available for translational research collaborations. Enabling novel analyses The generation of multi-modal omics datasets on the same samples will enable a systems biology approach to biomarker discovery through integrative analyses. For example, genomic and transcriptomic data may be combined to enable “eSNP” analysis. (19 additional diseases not shown) The MURDOCK Integrated Data Repository (MIDR) is the informatics core of the study, and provides the ability to store, manage, retrieve, and query study-related data and metadata. Version 1.0 contains clinical data only from Horizon 1. Version 2 planning is underway.

Murdock Institute for Business and Culture and receives support from NCRR: UL1 RR024128. Discussion Utility of the tools and data assets generated through each horizon of the MURDOCK Study will be measured in terms of uptake by the research community and generation of currency ranging from impact in peer review publication, to products launched from commercial sector collaboration. The authors invite interested investigators to take full advantage of this rich resource by contacting the MURDOCK Study team (murdock-study@duke.edu) to explore opportunities for collaboration. Horizon 1 In Horizon 1, investigators generated metabolomics, proteomics, gene expression, and genotype data for existing cohorts from several different disease areas. These data, along with clinical outcomes, were used to perform biomarker discovery to predict events, disease progression, and response to therapy. Overview of Horizon 1 Studies
