Electronic Medical Records and Genomics (eMERGE) Network


The Electronic Medical Records and Genomics (eMERGE) Network was announced in September 2007 (RFA HG-07-005). It is a National Institutes of Health (NIH)-organized and funded consortium of U.S. medical research institutions. The Network brings together researchers with a wide range of expertise in genomics, statistics, ethics, informatics, and clinical medicine from leading medical research institutions across the country to achieve its overall goals.

The primary goal of the eMERGE Network is to develop, disseminate, and apply approaches to research that combine DNA biorepositories with electronic medical record (EMR) systems for large-scale, high-throughput genetic research. In eMERGE Phase I (September 2007 - July 2011), each institution participating in the consortium led the studies of the relationship between genetic variation and at least two common human traits among the network participants, using the technique of genome-wide association analysis. Such studies involve testing hundreds of thousands of genetic variants called single nucleotide polymorphisms (SNPs) throughout the genome in people with and without a condition of interest. A fundamental question is whether electronic medical record (EMR) systems can serve as resources for such complex genomic analysis of disease susceptibility and therapeutic outcomes, across diverse patient populations. In addition, the consortium includes a focus on social and ethical issues such as privacy, confidentiality, and interactions with the broader community. During the past four years, the network has established a rich culture of collaboration. During Phase I, the network established a rich culture of collaboration.

Given the success of eMERGE Phase I, the eMERGE Network has transitioned to Phase II (August 2011 - July 2015). A key goal of eMERGE Phase II is to explore the best avenues to incorporate genetic variants into EMR for use in clinical care such as improvement of genetic risk assessment, prevention, diagnosis, treatment, and/or accessibility of genomic medicine (RFA-HG-10-009 and RFA-HG-10-010). Consent, education, regulation and consultation issues related to the use of genomic data in clinical care will also be studied. eMERGE continues to discover genomic variants associated with clinical conditions identified using EMRs and to develop algorithms for electronic phenotyping. To expand the number and diversity of participating eMERGE sites under the currently available budget, two new sites that include racial/ethnic minorities and rural populations were included in the eMERGE Network in 2011. In August 2012, two new sites that include pediatric populations were included in the eMERGE Network.

As eMERGE has become increasingly known in the scientific community, a wide range of institutions are interested in collaboration with eMERGE given that genomic research in biorepositories linked to electronic medical records and application of genomic results to clinical care has been or will be initiated in those institutions. To facilitate collaboration, external institutions may apply for affiliate membership to the eMERGE Network. Information about affiliate membership such as benefits, criteria for participation, and application process can be found at the eMERGE webpage.
