Exome sequencing (ES) and whole genome sequencing (WGS) are transformative new tools for discovery of genetic risk factors for both rare and common diseases and offer the potential of personalized genetic risk profiling in a single, cost-effective test. Because of the large number of variant results simultaneously identified, the number of results with potential clinical utility-including those that are unanticipated, and the evolving utility of results over time-use of these technologies challenges existing models of returning results to research subjects and patients.

Noninvasive prenatal genetic testing, which utilizes cell-free fetal DNA and advances in sequencing technology, is revolutionizing the practice of obstetrics. While currently used as a screen for a limited number of aneuploidies and genetic conditions, noninvasive testing is anticipated to employ whole fetal exome and genome sequencing to identify not only monogenic disorders but also microduplications, microdeletions, and variants of uncertain clinical significance.

Genomics-based technologies are increasingly used in clinical care and are highly relevant to public health because of their potential use in assessing risk, diagnosing, and developing treatment plans. Access to genomic tests often depends on cost and coverage of services by the health plan. No studies, to our knowledge, identify whether access and reimbursement issues relating to guideline-recommended pharmacogenomic tests exist, and what the potential implications of barriers to access and/or differential access for patients, providers, and society are.

Prenatal testing is evolving in two important ways: first, advances in genomic medicine mean that samples of fetal DNA obtained with invasive methods (such as amniocentesis) can be analyzed using microarray analysis or whole genome sequencing, revealing far more information about the fetus's genetic make-up than was previously possible; and second, new, non-invasive prenatal tests have been introduced that isolate fragments of fetal DNA circulating in a pregnant woman's blood, making possible safe, highly accurate genetic testing much earlier in pregnancy than was previously possi

The eMERGE project 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 conduct research in genomics, including discovery, clinical implementation and public resources. The primary goal of eMERGE is to develop, disseminate, and apply approaches to research that combine biorepositories with electronic medical record (EMR) systems for genomic discovery and genomic medicine implementation research.

A big data ecosystem is evolving in our society in which people may have, or feel they have, little control over the flow of their personal health information, and thus their privacy. Further, although there has been significant discussion related to big data and privacy at the highest levels of government, there is little consensus among scholars and stakeholders as to what privacy actually is, not to mention a lack of data from individuals as to personal conceptions of privacy.

Genomic literacy plays a critical role in informed decision-making for genomic testing, in the implementation of the test and the accurate interpretation of the results, and in our policy making process as a society. The National Human Genome Research Institute's 2011 vision for the future of genomic medicine specifically cites the need for both providers and consumers to achieve genomic literacy. Yet despite its importance, there is no effective tool for assessing genomic literacy.

With the dramatic reduction in the cost of whole genome sequencing (WGS), genomic data are becoming increasingly available and have the potential to advance public health and promote personalized medicine. However, human genomic data usually carry sensitive personal information making data owners cautious about sharing it and genomic privacy is emerging as a big challenge for the entire biomedical community. In this proposal, we will develop novel methods for genomic privacy protection, which will facilitate genomic research.

Whole genome sequencing has vast potential to improve the care of generally healthy adults by identifying predispositions for disease to facilitate targeted prevention and screening efforts, by informing treatment options when illnesses do develop, and more. It may also cause more harm than good through false-positive findings, through unnecessary monitoring because of incomplete genetic penetrance, and because the conditions identified by genomic sequencing may lack effective prevention options.

The advent of clinical genome sequencing to identify patients at risk for serious diseases and to tailor treatments promises to greatly improve health outcomes and provide a foundation for the delivery of Precision Medicine. However, even as laboratory methods to perform sequencing become highly efficient, uncertainty around the optimal breadth and economic value of sequencing as well as ambiguity around which individuals should be tested presents a critical barrier to wider use.
