A baby born with a super rare, deadly disorder just became the first person ever to get a one-of-a-kind, personalized gene therapy—and it’s working! KJ Muldoon was facing a future of strict diets, risky transplants, and scary odds, but thanks to a CRISPR-based treatment made just for him, he’s now thriving and hitting milestones. Even when he got sick (which usually means disaster for kids like him), he bounced back like a champ. This could totally change the game for rare diseases! #GeneTherapy #MedicalBreakthrough #CRISPR #RareDisease #ScienceNews #Health
