PRIMED has developed a data model that systematically organizes and retains detailed population descriptor data, providing flexibility for downstream analyses and adhering to NASEM recommendations on distinguishing descriptors (axes of measurement) from labels (measured values); see ASHG 2024 abstract.
Social and ethical considerations to responsibly develop and implement PRS
PRIMED is collecting use cases of common applications of PRS in research and healthcare to highlight best practices and practical concerns, with added emphasis on the conceptualization and use of ancestry and on downstream clinical implementation.
PRIMED is collaborating with the eMERGE network on a manuscript that addresses the considerations and concerns of PRS development and implementation, drawing from the experiences of both consortia.
