Description. While dwarfism is sometimes used to describe achondroplasia, a condition characterized by short stature and disproportionately short arms and legs, it is also used more broadly to refer to a variety of conditions resulting in unusually short stature in both children and adults.
There are two possible causes of achondroplasia. One possible cause is a genetic mutation in the fibroblast growth factor receptor 3 (FGFR3) gene located on chromosome 4. The other possible cause is that the condition can be inherited from a parent with achondroplasia.
