Colton Nover, 10, works on a report for school with his mother, Holly Nover in their kitchen Wednesday, Feb. 16, 2022, in St. Johns, Fla. Both mother and son have an issue with stuttering. University of Delaware speech disorder researcher Ho Ming Chow says, “We know stuttering has a really strong genetic component,” Though several genes may be involved and the exact genetic causes may vary by child, “they probably affect the brain in a similar way.”
