Genome Sequencing for Expanded Newborn Screening and Early Intervention: Study Sheds Light
Advertisement
Early results from a study of newborn screening methods show that DNA analysis picks up many more preventable or treatable serious health conditions than standard newborn screening and is favored by most parents who are offered the option. The findings were published in the JAMA network.
The study called GUARDIAN is one of the first large-scale studies in the world to use genome sequencing as a method for newborn screening and is the first to publish preliminary results.
“The results show us that genome sequencing can radically improve children’s medical care,” says Joshua Milner, professor of Pediatrics, director of Allergy/Immunology and Rheumatology at Columbia University Vagelos College of Physicians and Surgeons, and one of the study’s co-authors.
“Genome sequencing allows us to detect things that cause serious illness and take action to prevent those illnesses in a significant number of children, not just a few rare cases,” says Milner, who is also the chief of the allergy, immunology and rheumatology services at NewYork-Presbyterian Morgan Stanley Children’s Hospital. “It should be instituted as the next standard for newborn screening because it can detect so much more than current methods.”
