Achondroplasia

Achondroplasia is one of the most common causes of short stature. People with this condition have an average body size, but shorter limbs. This is because the bones in their arms and legs grow more slowly, both in the womb and throughout childhood. Most people with achondroplasia do not consider themselves disabled, just different. Young children with achondroplasia may have hearing, speech or breathing problems but all of these can be treated.
