Orpha Number: 199351

Definition
A rare neurodegenerative disease usually presenting before the age of 30 and which is characterized by dystonia, L-dopa-responsive parkinsonism, pyramidal signs and rapid cognitive decline.

Epidemiology
Prevalence is unknown. Only 14 cases have been reported to date.

Clinical description
Disease onset occurs in late adolescence or early adulthood (usually before the age of 30) and usually presents with parkinsonism (tremor, rigidity, bradykinesia), dystonia and rapid cognitive decline. Eye movement abnormalities (supranuclear vertical gaze palsy, eyelid opening apraxia), pyramidal tract signs, and psychiatric features such as depression and personality changes have also been reported in some patients. Dopaminergic treatment is initially successful with regard to parkinsonism, but the development of prominent dyskinesias often follows.

Etiology
Adult-onset dystonia-parkinsonism is caused by mutations in the phospholipase A2, group VI (PLA2G6) gene located on chromosome 22q13.1.

Genetic counseling
Adult-onset dystonia-parkinsonism is inherited in an autosomal recessive manner, and genetic counseling is possible and recommended.

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.

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.
