Treating 'Fragile X Syndrome' Autism Symptoms

LOS ANGELES -- You've probably never heard of it, but one in three kids with autism has Fragile X Syndrome. It's a disorder involving chromosomes that can be diagnosed while your baby's still in the womb. Now a new treatment is helping kids with Fragile X get rid of some of the symptoms that affect them developmentally.
Holly is her mom's little princess. But this girl's fairy tale started with a scare. While pregnant with Holly, Vicki Davis found out she was a carrier of Fragile X Syndrome.
"I had never heard of it. I had no clue what it was," said Vicki.
It's a mutation of a gene on the X chromosome that leads to a lack of protein production, critical for development. It's one of the most common causes of mental retardation.
