The Dwarf Don Sebastián de Morra, by Velázquez.

Dwarfism is used to describe a person of short stature, less than 4 feet, 10 inches (147 cm). This is often, though not always, because of a medical condition. People with this condition are called dwarves or little people. A similar term for short people is midget; however, dwarves and midgets are not the same. Midgets are perfectly proportioned humans, while dwarves have a large head and misshapen limbs and torsos.

Dwarfism is usually caused by the person inheriting an allele (a mutant gene), which produces a defect in development. Defects caused by genetics are the main kind of congenital defects, and usually cannot be cured.

The most common cause of dwarfism is a defect in bone development called achondroplasia, in which the limbs are short in proportion to the body. This accounts for 70% of cases.

Extreme shortness, but with body parts of normal proportions, may be caused by growth hormone deficiency, once known as pituitary dwarfism.[1]

There are more than 200 other conditions which may cause dwarfism.[2]

In the 19th century in the United States, people with dwarfism were a major attraction of many circus sideshows. The most famous little people in the history of the American circus are General Tom Thumb and Michu.[3]
