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.
