How new genomic approaches are helping diagnose and treat our tiniest patients

Welcoming a new baby brings boundless love, joy, and the usual sleepless nights of early parenthood. But in the NICU, when a newborn is unexpectedly sick, it’s the uncertainty that keep parents awake.

In this episode, our investigation takes us inside the neonatal intensive care unit, where genomic tools are mapping medical mysteries in record time. You’ll hear the remarkable story of “Baby KJ,” the first newborn to receive a personalized CRISPR treatment; insights from pediatric geneticist Dr. Tara Wenger on how new approaches to testing are changing care; and the story of Meredith Thomas– a mother whose fight for answers helped uncover a diagnosis that saved her daughter’s life.

From faster diagnoses to fairer care, join Dr. Kaylee Byers to learn how these genomic breakthroughs are redefining what’s possible for newborns and their families.
