Is JAMA’s GUARDIAN Nod Quietly Reframing GeneDx (WGS) as a Core Newborn Genomics Platform?

• In December 2025, GeneDx announced that its GUARDIAN newborn genomic screening study was selected for JAMA’s highly selective Research of the Year Roundup, recognizing peer-reviewed results showing a 72% parental consent rate, a 3.7% screen-positive rate, and a high rate of diagnoses beyond traditional newborn screening.
