The Genetics Podcast EP 224: Genomic newborn screening in Australia: From pilot studies to population-scale programs with Zornitza Stark of the University of Melbourne
Jan 29, 2026
Zornitza Stark, clinical geneticist and translational genomics leader at the University of Melbourne, talks genomic newborn screening and rapid sequencing. She describes the BabyScreen+ pilot, scaling challenges like automation and AI for variant curation, family-wide cascade testing and psychosocial needs, gene-selection criteria, equity and representativeness concerns, and the infrastructure and policy needed for national programs.

Episode notes
Life-Saving Immunodeficiency Case
- One baby with severe immunodeficiency became unwell within weeks but was monitored and received curative bone marrow transplant.
- The genomic result enabled prompt treatment that was potentially life-saving.
Family-Wide Impact Of Newborn Genomic Results
- Genomic newborn screening will uncover inherited dominant conditions with immediate family implications beyond pediatric care.
- Programs must plan links to adult services and psychosocial support for unexpected parental results.
Huge Variation In Gene Lists Across Studies
- Different pilot studies use widely varying gene lists despite similar selection criteria, limiting cross-study comparisons.
- Only ~80 genes overlapped across four contemporaneous studies, highlighting the need for harmonization.
