Summary Summary

The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.

Orpha Number: 199351

Disease definition

Adult-onset dystonia-parkinsonism is 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.

Symptoms 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.
