The Genetics Podcast
EP 123: The ethics of newborn genome screening: Actionable insights and beyond with Holly Peay, Senior Research Scientist at the Research Triangle Institute
February 22, 2024
This week we’re joined by Holly Peay, Senior Research Scientist in Bioethics and Genetic Counseling at the Research Triangle Institute (RTI), and Director of the pioneering Early Check Study. Holly and Patrick discuss the Early Check programme, which is offering whole genome screening to newborns and has successfully screened 1,100 babies to date. They talk about the ethical challenges raised by comprehensive newborn screening, the intersection of bioethics, genetics, and genomics, and how to approach healthcare decisions against a backdrop of complex phenotypes and multiple risk factors.
