Wildervanck syndrome

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease

no.svg

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype

no.svg

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

no.svg

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder

no.svg

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

no.svg

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

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.[1][2] 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.[3][4] 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.[2]

Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause

The exact cause of Wildervanck syndrome is not known. It is suspected to be a polygenic condition, meaning that many genetic factors may be involved.[2][3] Environmental factors may also be involved, indicating that this condition may be due to many factors (multifactorial).[2]

Organizations

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
