Causes, incidence, and risk factors
Most patients with acrodysostosis have no family history of the disease. However, sometimes the condition is passed down from parent to child. Parents with the condition have a 1 in 2 chance of passing the disorder to their children.
There is a slightly greater risk with fathers who are older.

Problems with the skin, genitals, teeth, and skeleton

Short head, measured front to back (brachycephaly)
Small, upturned broad nose with flat bridge
Unusual features of the face (short nose, open mouth, jaw that sticks out)

Orthopedic care, early intervention, and special education are recommended.
Problems depend on the degree of skeletal involvement and intellectual disability
. In general, patients do relatively well.
