Familial Spinocerebellar Ataxia Type 2 Parkinsonism Presenting as Intractable Oromandibular Dystonia

We have previously described a Korean family afflicted with spinocerebellar ataxia type 2 (SCA2) parkinsonism in which genetic analysis revealed CAG expansion of 40 repeats in the ATXN2 gene. The affected members presented with levodopa-responsive parkinsonism without cerebellar ataxia. Some show...

Summary:We have previously described a Korean family afflicted with spinocerebellar ataxia type 2 (SCA2) parkinsonism in which genetic analysis revealed CAG expansion of 40 repeats in the ATXN2 gene. The affected members presented with levodopa-responsive parkinsonism without cerebellar ataxia. Some showed motor fluctuation and dyskinesia, further mimicking idiopathic Parkinson’s disease (PD). Herein, we report a member of this family who developed jaw-opening and lingual-protrusion dystonia as the chief presentation
