A 9-year-old girl, who had no family history of neurologic diseases in the first-degree relatives, had a 3-year history of progressive myoclonus epilepsy (PME). A thorough laboratory investigation was normal. As two sisters of her paternal grandmother were said to have Huntington's disease (HD), the authors looked for HD and found a CAG repeat expansion of 115 repeats. This diagnosis should be considered in addition to other causes in patients with PME. Moreover, the current case further supports the notion that HD should be considered even when a family history is not obvious.

D006816 Huntington Disease A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea.
