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.
Achondroplasia (from the Greek for without cartilage growth) is a condition that results in dwarfism. It is caused by a mutation in the FGFR3 (fibroblast growth factor receptor 3) gene.The FGFR3 gene is located on the short arm of chromosome 4 at position 16.3.Click FGFR3 Gene for more detailed information on how a defect in this gene can lead to achondroplasia. This article also discusses the role of FGFR3 in other conditions, such as bladder cancer.).
