Gabby Williams has the facial features and skin of a baby, and she needs to be cared for as if she is a newborn, ABC News reported.
The little girl from Billings, Mont., weighs only 11 pounds, and has a mysterious condition, that slows her rate of aging.
Her mother Mary Margret Williams told the publication that Gabby hasn’t changed much over the years.
She said that last time when they weighed her, she was up a pound to 11 pounds and she’s gotten a few more haircuts.
Meanwhile, medical researcher Richard F. Walker, who has been trying to find the genetic off-switch to stop the aging process, has been studying Gabby from last two years along with two other people who have striking similarities.
Walker explained that physiological change, or what he calls “developmental inertia,” is essential for human growth as humans never develop without that process.
The doctor said if they could identify the gene and then at young adulthood they could silence the expression of developmental inertia, they will be able to achieve biological immortality.
