<front><div type="abstract" xml:lang="en"><p id="P3">Progressive myoclonus epilepsies (PMEs) are a group of rare, inherited disorders manifesting with action myoclonus, tonic-clonic seizures, and ataxia. We exome-sequenced 84 unrelated PME patients of unknown cause and molecularly solved 26 cases (31%). Remarkably, a recurrent <italic>de novo</italic>
mutation c.959G>A (p.Arg320His) in <italic>KCNC1</italic>
was identified as a novel major cause for PME. Eleven unrelated exome-sequenced (13%) and two patients in a secondary cohort (7%) had this mutation. <italic>KCNC1</italic>
encodes K<sub>V</sub>
3.1, a subunit of the K<sub>V</sub>
3 voltage-gated K<sup>+</sup>
channels, major determinants of high-frequency neuronal firing. Functional analysis of the p.Arg320His mutant channel revealed a dominant-negative loss-of-function effect. Ten patients had pathogenic mutations in known PME-associated genes (<italic>NEU1, NHLRC1, AFG3L2, EPM2A, CLN6, SERPINI1</italic>
). Identification of mutations in <italic>PRNP, SACS</italic>
, and <italic>TBC1D24</italic>
expand their phenotypic spectrum to PME. These findings provide important insights into the molecular genetic basis of PME and reveal the role of <italic>de novo</italic>
mutations in this disease entity.</p>

<abstract><p id="P3">Progressive myoclonus epilepsies (PMEs) are a group of rare, inherited disorders manifesting with action myoclonus, tonic-clonic seizures, and ataxia. We exome-sequenced 84 unrelated PME patients of unknown cause and molecularly solved 26 cases (31%). Remarkably, a recurrent <italic>de novo</italic>
mutation c.959G>A (p.Arg320His) in <italic>KCNC1</italic>
was identified as a novel major cause for PME. Eleven unrelated exome-sequenced (13%) and two patients in a secondary cohort (7%) had this mutation. <italic>KCNC1</italic>
encodes K<sub>V</sub>
3.1, a subunit of the K<sub>V</sub>
3 voltage-gated K<sup>+</sup>
channels, major determinants of high-frequency neuronal firing. Functional analysis of the p.Arg320His mutant channel revealed a dominant-negative loss-of-function effect. Ten patients had pathogenic mutations in known PME-associated genes (<italic>NEU1, NHLRC1, AFG3L2, EPM2A, CLN6, SERPINI1</italic>
). Identification of mutations in <italic>PRNP, SACS</italic>
, and <italic>TBC1D24</italic>
expand their phenotypic spectrum to PME. These findings provide important insights into the molecular genetic basis of PME and reveal the role of <italic>de novo</italic>
mutations in this disease entity.</p>
