Arkless-Graham; Acrodysplasia; Maroteaux-MalamutDefinition Return to top
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.
Causes Return to top
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.
Symptoms Return to top
Exams and Tests Return to top
A physical exam confirms the symptoms and signs of this disorder.
Findings may include:
In the first months of life, x-rays may show spotty calcium deposits, called stippling, in bones (especially the nose). Infants may also have short bones, early growth of bones of the hands and feet, shortening of the forearm bones near the wrist, and abnormally short fingers and toes (brachydactyly).
Treatment Return to top
Treatment depends on what physical and cognitive problems are present.
Orthopedic care as well as early intervention and special education are recommended.
Outlook (Prognosis) Return to top
Problems depend on the degree of skeletal involvement and mental retardation. In general, patients do relatively well.
Possible Complications Return to top
When to Contact a Medical Professional Return to top

Prevention Return to top
