Wildervanck syndrome, sometimes called cervico- oculoacoustic syndrome, is a very rare disorder almost exclusively affecting females. Currently, Wilderbank syndrome is thought to be the result of random genetic mutations. According to the National Organization for Rare Disorders (NORD, 2000a), it is comprised of a triad of particular conditions: congenital deafness (caused by a malformed bone in the inner ear), Klippel-Feil syndrome (KFS), and Duane syndrome.
