Uniprot Description A form of dystonia that responds to L-DOPA treatment without side effects. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures.

It is characterized by postural and motor disturbances showing marked diurnal fluctuation. Torsion of the trunk is unusual. Symptoms are alleviated after sleep and aggravated by fatigue and exercise.
