Summaries for Developmental and Epileptic Encephalopathy 68

UniProtKB/Swiss-Prot : 73 Epileptic encephalopathy, early infantile, 68: A form of epileptic encephalopathy, a heterogeneous group of severe childhood onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. EIEE68 is an autosomal recessive form characterized by onset of twitching and/or myoclonic jerks in infancy. The disorder progresses to refractory generalized tonic-clonic seizures, often resulting in status epilepticus, loss of developmental milestones, and early death. Other features include delayed development, axial hypotonia, spasticity of the limbs, and clonus.

MalaCards based summary : Developmental and Epileptic Encephalopathy 68, is also known as developmental and epileptic encephalopathy, 68. An important gene associated with Developmental and Epileptic Encephalopathy 68 is TRAK1 (Trafficking Kinesin Protein 1). Related phenotypes are microcephaly and flexion contracture

Disease Ontology : 12 A developmental and epileptic encephalopathy characterized by progressive development of seizures starting in infancy, developmental delay, axial hypotonia, spasticity of the limbs, clonus, and cortical atrophy that has material basis in homozygous or compound heterozygous mutation in TRAK1 on chromosome 3p22.1.

OMIM® : 57 Developmental and epileptic encephalopathy-68 (DEE68) is an autosomal recessive neurologic disorder characterized by onset of twitching and/or myoclonic jerks in infancy. The disorder progresses to refractory generalized tonic-clonic seizures, often resulting in status epilepticus, loss of developmental milestones, and early death. Other features include delayed development, axial hypotonia, spasticity of the limbs, and clonus. Brain imaging may show cortical atrophy (summary by Barel et al., 2017).
