What causes achondroplasia?

How does achondroplasia affect a person?
Achondroplasia impairs the growth of bone in the limbs and causes abnormal growth in the spine and skull. Although the cause is a genetic mutation, only about one out of five cases is hereditary (passed down by a parent).
Can achondroplasia be cured?
Currently there are no treatments able to reverse achondroplasia, which is caused by mutations in a gene — called FGFR3 — that result in the excess production of proteins that slow bone growth, nor are there ways to treat the genetic culprit itself.
How is achondroplasia diagnosed?
Achondroplasia can be diagnosed before birth by fetal ultrasound. This test uses sound waves and a computer to create images of the baby growing in the womb. DNA testing can also be done before birth to confirm fetal ultrasound results. The condition can also be diagnosed after birth with a physical exam.
