Acrodysostosis also known as Arkless-Graham syndrome[1] or Maroteaux-Malamut syndrome[2][3] is a rare congenital malformation syndrome which involves shortening of the interphalangeal joints of the hands and feet, mental deficiency in approximately 90% of affected children, and peculiar facies. Other common abnormalities include short head (as measured front to back), small broad upturned nose with flat nasal bridge, protruding jaw, increased bone age, Intrauterine growth retardation, juvenile arthritis and short stature. Further abnormalities of the skin, genitals, teeth, and skeleton may occur.
Most reported cases have been sporadic, but it has been suggested that the condition might be genetically related i.e. in a autosomal dominant mode of transmission. Both males and females are affected. The disorder has been associated with older parental age.
A PRKAR1A mutation has been identified in acrodysostosis with hormone resistance.[4]
