Progeria is a very rare genetic disorder in children characterized by dramatic premature aging. Newborns with progeria may appear normal for up to a year, but then will begin to exhibit symptoms like balding, aged-looking skin, a pinched nose, a small face, and a sudden halt in height and weight gain. They may also suffer from a myriad of problems experienced by the elderly, such as stiffness and dislocation of joints and cardiovascular disease. Despite stunted growth and rapid deterioration, these children often have an average intelligence comparable to their peers.
There is limited knowledge about Progeria because it is so rare, but it is known to be a new mutation in the LMNA gene that happens spontaneously. There is no cure for progeria, but medications may alleviate symptoms or delay its progression. Due to the severity of this disorder, the average lifespan is usually only 13 years.
