This week on The Genetics Podcast, Patrick is joined by Zornitza Stark, Professor at the University of Melbourne and Co-Group Leader at the Murdoch Children’s Research Institute. Using early findings from the BabyScreen+ genomic newborn screening study, they examine feasibility, clinical impact, and family-wide implications beyond standard screening, and consider what these insights mean for infrastructure, policy, and equitable implementation at scale.
