A novel protein tyrosine phosphatase gene is mutated in progressive mioclonus epilepsy of the Lafora type EMP2. Hum Mol Genet, 8pp. Differential diagnosis of progressive myoclonic epilepsies. Analytical tests, including a haemogram, renal, liver, and emfermedad profiles, enfermeead, ceruloplasmin, creatine kinase, antineuronal antibodies, and baseline and post-exercise lactate levels, all yielded normal results.
Disease progression was aggressive, with multiple generalised tonic-clonic, myoclonic, and partial seizures accompanied by visual symptoms that persisted in spite of treatment with several drug combinations.
