Coming to Grips with Genetic Exceptionalism: Roots and Reach of an Explanatory Model

Precision medicine at the crossroads

There are bioethical, institutional, economic, legal, and cultural obstacles to creating the robust-precompetitive-data resource that will be required to advance the vision of “precision medicine,” the ability to use molecular data to target therapies to patients for whom they offer the most benefit at the least risk. Creation of such an “information commons” was the central recommendation of the 2011 report Toward Precision Medicine issued by a committee of the National Research Council of the USA (Committee on a Framework for Development of a New Taxonomy of Disease; National Research Council. Toward precision medicine: building a knowledge network for biomedical research and a new taxonomy of disease. 2011). In this commentary, I review the rationale for creating an information commons and the obstacles to doing so; then, I endorse a path forward based on the dynamic consent of research subjects interacting with researchers through trusted mediators. I assert that the advantages of the proposed system overwhelm alternative ways of handling data on the phenotypes, genotypes, and environmental exposures of individual humans; hence, I argue that its creation should be the central policy objective of early efforts to make precision medicine a reality.

Captious certainties: makings, meanings and misreadings of consumer-oriented genetic testing

Members of the scientific and medical communities concerned with genetic testing might wonder, why cultural and ethical analyses of genetic testing are increasing again, especially since legal frameworks have, by now, come to provide more solid grounds for the routine application of genetic testing on both levels of application, diagnostics, and prediction. This contribution aims to shed light on the changing concept of genetic testing as it is raised by novel cultural practices and perceptions mainly triggered by direct-to-consumer predictive testing, including the phenomenon of a new genetic exceptionalism "from below". We are seeking to determine what is at stake in this practice and what consequences arise from it for the medical and scientific community. What exactly happens as we move from diagnostic to prognostic medicine? Above all, this article pivots on the notion of captious certainties, a concept, which we will elaborate on as our argument progresses.
