All people with achondroplasia have short stature. The average height of an adult male with achondroplasia is 131 centimeters (4 feet, 4 inches), and the average height for adult females is 124 centimeters (4 feet, 1 inch).bout 80 percent of people with achondroplasia have average-size parents; these cases result from new mutations in the FGFR3 gene. In the remaining cases, people with achondroplasia have inherited an altered FGFR3 gene from one or two affected parents.
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.).
