This is in contrast to another rare but similar premature aging syndrome, dyskeratosis congenita (DKC), which is inheritable and will often be expressed multiple times in a family line. Scientists are particularly interested in progeria because it might reveal clues about the normal process of aging.
The earliest symptoms include failure to thrive and a localized scleroderma-like skin condition.
As the child ages past infancy, additional conditions become apparent. Limited growth, alopecia, and a distinctive appearance (small face and jaw, pinched nose) are all characteristic of progeria. The people diagnosed with this disease usually have small, fragile bodies, like those of elderly people. Later, the condition causes wrinkled skin, atherosclerosis, and cardiovascular problems.
