We report a 63 year old woman with familial HH with a four year history of progressive gait disturbance, chorea, and mild cervical and laryngeal dystonia. Her movement disorder was thought to be related to the haemochromatosis. On further investigation, analysis for the Huntington’ s disease expansion was positive. A review of the seven published cases of movement disorders associated with HH as well as data concerning brain iron deposition in this condition leads us to debate the causal link between movement disorders and HH. We suggest that ovement disorders are rare in association with HH, and that such patients should be thoroughly investigated for another cause for their movement diorder.展开更多

We screened 58 individuals with a range of myoclonic/dystonic syndromes fo r SGCE mutations. We found mutations (four of them novel) in six (21%) of the 2 9 patients with essential myoclonus and myoclonic dystonia, but did not find mut ations in the 29 patients with other phenotypes.展开更多
