Abstract:
One hundred sixty-two patients with Korean primary dystonia patients were screened for DYT1 mutation. Five patients were positive for DYT1 mutation. Generalized dystonia patients have higher rate of DYT1 mutation (3/7). Their onset age is young (7-20; mean 13.4). Two patients were found to have segmental dystonia. Like Japanese patients with DYT1 mutation, axial muscle involvement is notable.
