What is the definition of Acrodysostosis?
Acrodysostosis refers to a group of genetic disorders of bone growth. Common signs and symptoms include very short fingers and toes, underdeveloped facial bones, a small nose, and short stature. Many individuals with Acrodysostosis have developmental delays and intellectual disability.

The disease is inherited in an autosomal dominant manner, with most reported cases occurring for the first time in a family due to a new genetic change.
