What is Progeria exactly?

Progeria rapidly ages children due to a point mutation in the LMNA gene. A protein made by this gene controls the structure and frame of the cells' membrane. With this disease, Lamin A's production does not occur. Therefore, the cells take on a warped appearance. The exact reason for the disease remains debatable. Evidence points to heredity, but not enough is known to be certain. Progeria somehow hinders the development of most body systems, while negatively aging them.
