          Abstract

          LA EPILEPSIA GENERALIZADA CON CONVULSIONES FEBRILES PLUS (EGCF+), es una entidad relativamente común. Se caracteriza por convulsiones de tipo generalizado con una gran variabilidad fenotípica; se presenta desde los 3 meses de edad y persiste más allá de los 6 años; las convulsiones pueden ser precipitadas por fiebre pero se presentan también sin ella. La enfermedad se ha asociado a herencia autosómica dominante con penetrancia incompleta, en la que intervienen mutaciones de los genes que codifican los canales iónicos de sodio dependientes del voltaje y de los canales iónicos de cloro en las neuronas del Sistema Nervioso Central (SNC). El amplio fenotipo de la EGCF+ se ha encontrado en asociación con otras entidades como la Epilepsia Mioclónica Severa del Lactante (EMSL) y la Epilepsia Generalizada Tónico-Clónica Intratable de la Infancia (EGTCII), las cuales han presentado mutaciones comunes con las de la EGCF+, según informes recientemente publicados. Esta revisión pretende recopilar información de la literatura publicada sobre la EGCF+, con el objeto de brindar al lector un mejor conocimiento de esta entidad y de su asociación con las mutaciones que participan en su patogenia.

          Translated abstract

          Generalized Epilepsy with Febrile Seizures Plus (GEFS+) is a frequent entity characterized by generalized seizures with a wide phenotypic variety; the age of onset is 3 months and it persists beyond 6 years. Seizures may or may not be induced by fever. The disease has shown an autosomic dominant trait, incomplete penetrance and association with mutations on the genes that encode voltage-dependent sodium channels and the chloride neuronal channels on the central nervous system. The wide spectrum GEFS+ phenotype has been related with others entities such as Severe Myoclonic Epilepsy of Infancy (SMEI) and Intractable Childhood Epilepsy with Frequent Generalized Tonic-Clonic Seizures (ICEGTC); they have mutations in common with GEFS+ according to several recently published articles. This review compiles up to date information about EGCF+ with the aim of giving the reader a knowledge of this entity and of its association with mutations that participate in its pathogenesis.

          Mutant GABA(A) receptor gamma2-subunit in childhood absence epilepsy and febrile seizures.

          Epilepsies affect at least 2% of the population at some time in life, and many forms have genetic determinants. We have found a mutation in a gene encoding a GABA(A) receptor subunit in a large family with epilepsy. The two main phenotypes were childhood absence epilepsy (CAE) and febrile seizures (FS). There is a recognized genetic relationship between FS and CAE, yet the two syndromes have different ages of onset, and the physiology of absences and convulsions is distinct. This suggests the mutation has age-dependent effects on different neuronal networks that influence the expression of these clinically distinct, but genetically related, epilepsy phenotypes. We found that the mutation in GABRG2 (encoding the gamma2-subunit) abolished in vitro sensitivity to diazepam, raising the possibility that endozepines do in fact exist and have a physiological role in preventing seizures.
