Acromesomelic dysplasia (AMD) is characterized by inhibition of growth of certain long bones (i.e. bones of the forearms and lower legs). As a result, affected individuals exhibit unusually short forearms and lower legs and short stature (short-limbed dwarfism).
A dwarf is a person of short stature - under 4' 10" as an adult. More than 200 different conditions can cause dwarfism. A single type, called achondroplasia, causes about 70 percent of all dwarfism. Achondroplasia is a genetic condition that affects about 1 in 15,000 to 1 in 40,000 people.
Campomelic dysplasia is a severe disorder that affects development of the skeleton, reproductive system, and other parts of the body. This condition is often life-threatening in the newborn period. This condition is often life-threatening in the newborn period.
