Progeria or meaning prematurely old is a rare and fatal genetic condition in which children exhibit symptoms resembling aging. It is also known as Hutchinson–Gilford progeria syndrome, Hutchinson–Gilford syndrome and Progeria syndrome.

Jonathan Hutchinson was the first to describe progeria in 1886. Later, in 1897, Hastings Gilford independently recorded the syndrome. The name Hutchinson–Gilford progeria syndrome came to being because of this. Researchers have great interest in progeria as it can shed light on  the normal process of aging which can be observed at an accelerated pace in progeria patients.

Progeria is extremely rare and currently there are about 35-45 known cases in the world. About 100 cases have been identified in medical history. Progeria is not hereditary and cannot be carried forward from parent to child as affected children do not usually live long enough to have children themselves.
