Genomic Newborn Screening Could Identify Childhood Cancer Predisposition

Genomic testing added to routine newborn screening of nearly 2,000 archived dried blood spots successfully identified children at increased risk for childhood cancer predisposition syndromes. The approach could enable earlier surveillance and intervention for hereditary cancers such as retinoblastoma and other pediatric malignancies. While promising, the study is relatively small and further validation in larger prospective cohorts is needed before integration into population-level screening programs.
