Myoclonus-dystonia (DYT11, DYT-SGCE) - a channelopathy?
Forskningsoutput: Tidskriftsbidrag › Debate/Note/Editorial
INTRODUCTION: Kaczyńska et al. reported a family with myoclonus-dystonia (M-D) caused by a truncating SGCE mutation, in which two members had epilepsy. Further, patients had mild psychiatric and developmental deficits. CLINICAL REFLECTIONS: Characteristic motor features of M-D include myoclonus, dystonia and tremor. A wide range of additional disease manifestations are known. A few patients with M-D have seizures. CLINICAL IMPLICATIONS: Altered neuronal excitability has been found in the pathogenesis of M-D. This may explain the partial effectiveness of antiepileptics and a lower seizure threshold, and could encourage trials of other membrane stabilisers. Careful clinical observations of seemingly well-known diseases remain important.
