Wildervanck syndrome is a condition that occurs almost exclusively in females and affects the bones in the neck, the eyes, and the ears.  It is characterized by Klippel-Feil anomaly (in which the bones of the neck fuse together), Duane syndrome (an eye movement disorder that is present from birth), and hearing loss. [1]  The cause of Wildervanck syndrome is unknown.  In most cases, affected individuals have no family history of the condition.
