For a few weeks last year, Michael Tranfaglia and Katie Clapp saw a remarkable change in their son, Andy, who'd been left autistic and intellectually disabled by fragile X syndrome. Andy, who is 25, became more social, more talkative and happier. "He was just doing incredibly well," his father says.
