A fifteen year old male standing full length next to a dog sitting on a chair. He suffers from progeria. Progeria is an extremely rare genetic condition wherein symptoms resembling aspects of aging are manifested at an early age. Those born with progeria typically live to their mid teens and early twenties. It is a genetic condition that occurs as a new mutation (de novo), and is rarely inherited. No treatments have been proven effective. As there is no known cure, few people with progeria exceed 20 years of age. At least 90% of patients die from complications of atherosclerosis, such as heart attack or stroke.
