Myoclonus-dystonia and spinocerebellar ataxia type 14 presenting with similar phenotypes: trunk tremor, myoclonus, and dystonia

Abstract

We describe three genetically confirmed myoclonus dystonia (M-D) patients and one spinocerebellar ataxia type 14 (SCA14) patient, presenting with a combination of trunk tremor, multifocal myoclonus and axial dystonia as predominant clinical features. We suggest that in patients with this M-D phenotype, without a mutation in the DYT11 gene, SCA14 should be considered.
