Description:Progeria is an extremely rare disease that afflicts about 200 kids in the world. But there's some hope for one teen who's participating in a new drug trial.
The disease causes rapid aging, a decrease in bone and muscle density, and increases the risk of stroke and heart attack in the children who are born with it.
The average age of death for these children is 13 years old. This boy is now 16 year old.(1:02)
