Somatosensory evoked potentials indicated a cortical origin of the myoclonus. There were no associated seizures. Some severely affected individuals developed signs of progressive cerebellar ataxia of variable severity late in the course of their illness. The phenotype was inherited in an autosomal dominant fashion. We demonstrated linkage to chromosome 16q21\u201022.1. We then sequenced all coding sequence in the critical region, identifying only a single cosegregating, novel, nonsynonymous mutation, which resides in the gene\n                      <jats:italic>NOL3<\/jats:italic>\n                      .
