This rare inherited condition affects the development of bones.
People with acrodysostosis have certain bones that mature rapidly, before they've had enough time to grow fully. The bones most often affected are those of the nose and jaw, and the long tubular bones of the hands and feet.
Abnormal bone development results in a collection of characteristic features, including a typical facial appearance (short nose, open mouth and prominent jaw), small hands and feet.
The gene responsible for acrodysostosis has not yet been identified and the condition may result from different genetic problems rather than one specific condition.
It appears to be inherited in an autosomal dominant fashion, and seems to be more common among older fathers.
There's no cure for acrodysostosis, but appropriate support, especially for learning disabilities, is important.
