Wildervanck syndrome is a condition that 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), and hearing loss. Wildervanck syndrome occurs primarily in females. In most cases, Wildervanck syndrome occurs randomly for unknown reasons in a family with no prior history (sporadically), though a deletion on the X chromosome was identified in one individual with Wildervanck syndrome. X-linked dominant inheritance has been suggested due to the high prevalence of affected females. Treatment is specific to each symptom and may include physical therapy, surgical intervention for skeletal, ocular, auditory, and cardiac abnormalities, and utilization of hearing aids.

How is Wildervanck syndrome inherited?
Wildervanck syndrome does not have a clear pattern of inheritance. In most cases, only one person in a family is affected. These cases are called isolated or sporadic because there is no family history of Wildervanck syndrome. Because this syndrome occurs mostly in females, it is possible that this condition has X-linked dominant inheritance. The lack of males with Wildervanck syndrome suggests that affected males have more severe features and do not survive to birth.

Can a person with Wildervanck syndrome have children?
It is not known if Wildervanck syndrome affects a person's ability to have a child. Because the cause of Wildervanck syndrome is also uknown, it is difficult to determine the chance that a child could inherit the condition from an affected parent.  At least one family has affected individuals in five generations.  There is also a report of an affected mother having two sons and a daughter who were not affected. 
To find out your specific risk of having a child with Wildervanck syndrome, we recommend that you consult with a genetics professional.
