I saw a movie with a kid who aged more quickly than normal. Was that progeria?
The movie Jack featured Robin Williams playing a boy who aged at four times the normal rate. While this is the general idea of progeroid diseases, Jack lacked all the other symptoms which characterize most progeria, such as short stature, bird-like facial features, etc. The disease that Jack had is fictional, and resembles true progeroid syndromes only superficially. Additionally, the movie Blade Runner featured a child who was prematurely aged, with a disease the movie called Methuselahs Syndrome. This child appears tentatively to be a case of progeria.
