摘要: Paroxysmal nonkinesigenic dyskinesia (PNKD) is characterized by attacks of dystonia or chorea lasting minutes to hours. Recently, mutations in the myofibrillogenesis regulator 1 gene (MR-1) have been identified 10 unrelated PNKD kindreds. The authors describe a Canadian family who does not MR-1 and links separate locus at 2q31. This indicates that there are least two different genes responsible for PNKD.
