Summaries for Developmental and Epileptic Encephalopathy 67

OMIM® : 57 Developmental and epileptic encephalopathy-67 (DEE67) is characterized by the onset of various types of seizures in the first months of life, although later onset may occur in milder cases. The seizures tend to be resistant to treatment. Affected individuals have global developmental delay with impaired motor and intellectual development, poor or absent speech, movement disorders, and stereotypic or autistic behavior (summary by Chatron et al., 2018). For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350. (618141) (Updated 05-Mar-2021)

MalaCards based summary : Developmental and Epileptic Encephalopathy 67, also known as developmental and epileptic encephalopathy, 67, is related to thrombocythemia 1 and essential thrombocythemia. An important gene associated with Developmental and Epileptic Encephalopathy 67 is CUX2 (Cut Like Homeobox 2). Affiliated tissues include eye, and related phenotypes are hypsarrhythmia and gait disturbance

Disease Ontology : 12 A developmental and epileptic encephalopathy characterized by onset in the first months of lifes of seizures, global developmental delay with impaired motor and intellectual development, poor or absent speech, movement disorders, and stereotypic or autistic behavior that has material basis in heterozygous mutation in CUX2 on chromosome 12q24.11-q24.12.

UniProtKB/Swiss-Prot : 73 Epileptic encephalopathy, early infantile, 67: 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. EIEE67 is an autosomal dominant form characterized by onset of seizures in infancy. Later onset of seizures in childhood may occur in some patients.
