\nGeneDx (Nasdaq: WGS), a leader in delivering improved health outcomes through genomic insights, today announced that the GUARDIAN (Genomic Uniform-screening Against Rare Disease In All Newborns) study has been recognized as part of JAMA<\/i>\u2019s annual Research of the Year Roundup<\/b><\/a>. This highly selective honor is reserved for the most impactful scientific contributions published across all JAMA<\/i> journals.\n<\/p>\n
\nThe recognition highlights the significance of GUARDIAN\u2019s peer-reviewed findings, which demonstrate the power of genomic newborn screening to identify serious, actionable childhood conditions more broadly than traditional newborn screening (NBS).\n<\/p>\n
\nThe published analysis from the first 4,000 newborns enrolled in GUARDIAN showed:\n<\/p>\n
- \n
- \nA 72% parental consent rate<\/b>, demonstrating strong family interest in genomic screening\n<\/li>\n
- \nA 3.7% screen-positive rate<\/b><\/li>\n
- 92% of screen-positive newborns had a confirmed diagnosis<\/b> for a condition not included in traditional NBS<\/b><\/li>\n<\/ul>\n
\nConditions identified through the study include long QT syndrome<\/b>, a rare cardiac condition associated with sudden infant death syndrome (SIDS) that can be effectively managed with beta-blockers; Wilson disease<\/b>, which can be treated with a liver transplant or managed through early zinc supplementation and a low-copper diet;1<\/sup> and severe combined immunodeficiency (SCID)<\/b>, which can be treated with stem cell transplantation or gene therapy.2<\/sup> While SCID is included in traditional newborn screening, some variants can be missed. In each case, early diagnosis enables timely intervention and meaningfully improves clinical outcomes.\n<\/p>\n
\n\u201cBeing included in JAMA\u2019s Research of the Year Roundup is a tremendous honor and reflects the dedication of the entire GUARDIAN team and the families who participate,\u201d said Wendy Chung, MD, PhD, GUARDIAN\u2019s principal investigator, clinical and molecular geneticist, and the Chief of Pediatrics at Boston Children\u2019s Hospital and Harvard Medical School. \u201cGUARDIAN demonstrates that genomic screening can identify serious childhood conditions earlier than ever before. This recognition strengthens our commitment to bringing these benefits to all newborns.\u201d Dr. Chung launched the study at NewYork-Presbyterian and Columbia University Irving Medical Center in 2022.\n<\/p>\n
\nGUARDIAN is one of the largest genomic newborn screening studies in the world and is open to all babies born at NewYork-Presbyterian hospitals in New York City. To date, the study has screened more than 20,000 newborns, with a long-term goal of enrolling 100,000 newborns. The program is designed to evaluate the feasibility, clinical impact, and equity considerations of implementing genomic screening alongside existing public health newborn screening programs.\n<\/p>\n
\n\u201cThis recognition from JAMA<\/i> reinforces what families and clinicians are seeing firsthand \u2013 that earlier, more precise genetic diagnosis can fundamentally change the trajectory of a child\u2019s life,\u201d said Katherine Stueland, President and CEO of GeneDx. \u201cGUARDIAN is setting the standard for how genomics can responsibly and effectively complement traditional newborn screening, ensuring more children get answers before symptoms begin and opening the door to earlier intervention, prevention of disease progression, and true precision genomic medicine.\u201d\n<\/p>\n
\n\u201cThe GUARDIAN program reflects the enormous power of the analysis of an individual’s genome in the provision of truly personalized medicine \u2014 delivered at the beginning of a lifetime,” said Rudolph Leibel, M.D., Chief of Pediatric Molecular Genetics at NewYork-Presbyterian\/Columbia University Irving Medical Center and a co-author of the study. \u201cThese same genetic data can ultimately also serve to inform diagnostic and therapeutic decisions throughout that lifetime, and will at some point soon likely become a standard of care. Dr. Chung and her associates have pioneered a remarkable advance.\u201d\n<\/p>\n
\nDiagnosing rare genetic conditions is often slow and complex, with many children waiting five years or more for an accurate diagnosis \u2013 if they receive one at all.3,4<\/sup> During this diagnostic odyssey, pediatric patients typically undergo multiple uninformative tests and incur thousands of dollars in healthcare costs before a diagnosis is reached.5 <\/sup>Earlier genetic diagnosis can fundamentally change this paradigm by enabling timely treatment, guiding clinical management, reducing unnecessary interventions, and connecting families to critical resources and support \u2013 ultimately improving outcomes for children and easing the burden on families and health systems. 6,7<\/sup><\/p>\n
\n\u201cNext-generation sequencing technologies, including whole genome sequencing, have radically improved the diagnostic yield for pediatric genetic disease and will make an equally deep impact in the context of genomic newborn screening, which we believe will save many children’s lives,\u201d said Swaroop Aradhya, PhD, Global Head of Medical Affairs at Illumina. \u201cJAMA’s recognition of the GUARDIAN study underscores this profound importance.\u201d\n<\/p>\n
\nThe GUARDIAN study is an ongoing collaboration between Columbia University Irving Medical Center and NewYork-Presbyterian, and the New York State Department of Health, with GeneDx providing genomic testing and interpretation and Illumina supporting sequencing technology and scientific collaboration. Together, they are generating critical evidence to inform the future of newborn screening and precision medicine.\n<\/p>\n

\n
<\/b>GUARDIAN (Genomic Uniform-screening Against Rare Diseases In All Newborns) is a research study conducted at Columbia University in collaboration with NewYork-Presbyterian, the New York State Department of Health, and Illumina, using whole genome sequencing (WGS) provided by GeneDx to screen 100,000 newborns for more than 250 genetic conditions not currently included in standard newborn screening. The goals of the study are to drive earlier diagnosis and treatment to improve the health of the babies who participate, generate evidence to support the expansion of newborn screening through genomic sequencing, and characterize the prevalence and natural history of rare genetic conditions.
