I met a little person the other day who said that he was a achondroplastic dwarf. I know there are different types of dwarfism; what is this type?

A person with achondroplasia, or an achondroplastic dwarf, is a person who is on average, less than four feet, four inches tall. Their limbs (arms and legs) are short, not in proportion with their trunk. They usually have a large head, flattened nose, and a curved spine and legs, as their most obvious signs.

The dwarfism is caused by a gene passed down from a parent.
