A rare, genetic, movement disorder characterized by early-onset, very slowly progressive choreiform movements that may involve variable parts of the body, typically aggravated by stress or anxiety, in various members of a family. Additional variable manifestations include hypotonia, often resulting in psychomotor delay (including gait disturbances) and dysarthria, as well as myoclonus, dystonia, behavioral symptoms (ADHD, obsessive-compulsive disorder), learning difficulties (particularly in writing) and spasticity with hyperreflexia and/or flexor/extensor plantar reflexes.
