What causes Beckwith-Wiedemann Syndrome?

Researchers link BWS to changes in the chromosome that regulates growth. Approximately 80% of children born with BWS don’t have a family history of BWS. Studies show 10% to 15% of children have a family history of Beckwith-Wiedemann Syndrome, meaning one parent has passed on genetic changes that drive BWS.
