Acrodysostosis is an extremely rare congenital (present at birth) disorder marked by problems in the bones of the hands, feet, and nose, and mental retardation.
Most patients with acrodysostosis have no family history of the disease. But sometimes the condition is passed down from parent to child as an autosomal dominant trait. That means parents with the condition have a 1 in 2 chance of passing the disorder on to their children.
