Polymyoclonus, Infantile

Robinson et al. (1977) described 2 second cousins with infantile polymyoclonus. No other familial cases have been described. The main clinical features are chaotic rapid conjugate ocular movements, ataxia, somatic myoclonus, and irritability. The syndrome is not progressive. It runs a protracted course with exacerbations and remissions. It has been called the 'dancing eyes, dancing feet syndrome.'
