GRIN1 Mutations in Early-Onset Epileptic Encephalopathy.
Investigators from Yokohama City University and other medical centers in Israel and Japan reported mutations on N-methyl-D-aspartate (NMDA) receptors subunit GRIN1 (GluN1) identified in patients with nonsyndromic intellectual disability and early-onset epileptic encephalopathy.
متن کاملEarly-onset epileptic encephalopathies: Ohtahara syndrome and early myoclonic encephalopathy.
Ohtahara syndrome and early myoclonic encephalopathy are the earliest presenting of the epileptic encephalopathies. They are typically distinguished from each other according to specific clinical and etiologic criteria. Nonetheless, considerable overlap exists between the two syndromes in terms of clinical presentation, prognosis, and electroencephalographic signature. Newer understandings of u...
متن کاملFunctional Analysis of a De Novo GRIN2A Missense Mutation Associated with Early-onset Epileptic Encephalopathy
NMDA receptors (NMDARs), ligand-gated ion channels, play important roles in various neurological disorders, including epilepsy. Here we show the functional analysis of a de novo missense mutation (L812M) in a gene encoding NMDAR subunit GluN2A (GRIN2A). The mutation, identified in a patient with early-onset epileptic encephalopathy and profound developmental delay, is located in the linker regi...
