A Miracle Baby's Remarkable Recovery: Gene Therapy Breakthrough

First instance of personalized gene therapy administered to a newborn baby in Pennsylvania

In a groundbreaking turn of events, an infant born with a life-threatening genetic condition is not only surviving but thriving after undergoing an experimental gene editing treatment. This medical marvel has researchers buzzing with excitement, as this custom therapy could pave the way for treating various rare genetic disorders that currently lack definitive treatments.

The lucky infant, KJ Muldoon from Clifton Heights, Pennsylvania, is one of the estimated 350 million people globally with rare diseases, many of which are genetic in origin. KJ was diagnosed shortly after birth with severe CPS1 deficiency, a condition affecting approximately one in a million newborns, and for which there is no known cure. Affected infants lack an enzyme necessary to remove toxic ammonia from their bodies, making liver transplants a viable option, albeit an invasive one, for some.

The Muldoons, parents Kyle and Nicole, both 34 years old, weighed the options and feared they might lose their precious baby. "We were like, you know, considering all the options, asking all the questions for either the liver transplant or something that's never been done before," Nicole admitted.

But they didn't settle for the status quo. They took a chance on what some say will revolutionize gene therapy: base editing, a method that flips the mutated DNA "letter" - or base - to the correct type without cutting the DNA strand. This approach, popularized by CRISPR, which won its inventors the Nobel Prize in 2020, reduces the risks of unintended genetic changes that can occur in traditional gene editing methods.

KJ received his first IV infusion with the gene editing therapy at Children's Hospital of Philadelphia and Penn Medicine in February. While he snoozed through the entire procedure, the room buzzed with excitement. Since then, he has made remarkable strides, eating more regularly, recovering well from illnesses, and requiring less medication. For his parents, even the smallest milestones are significant, like waving or rolling over.

Researchers acknowledge that it's still early days, and they will monitor KJ closely for years. But they're hopeful that what they learn from his case will help others battling rare diseases. In fact, scientists argue that creating custom treatments doesn't have to break the bank, as demonstrated by the team's work, which was partly funded by the National Institutes of Health. They claim that the cost was not far off from the average liver transplant and related care.

As the gene therapy field continues to advance, researchers expect that economies of scale will eventually drive down costs, making more personalized treatments accessible to those who need them. The initial work for custom therapies won't need to be repeated each time, either, as researchers can build upon existing knowledge and techniques. This opens the door to treating even the rarest of disorders, bringing hope to families who once felt helpless in the face of genetic diseases.

Carlos Moraes, a neurology professor at the University of Miami, emphasizes that breakthroughs like the one highlighted by KJ's case set the stage for further advances. "There are barriers, but I predict that they are going to be crossed in the next five to 10 years. Then the whole field will move as a block because we're pretty much ready," he said. And as KJ's story demonstrates, the world is eagerly awaiting further progress in gene therapy to help those fighting rare genetic disorders.
