Summaries for Developmental and Epileptic Encephalopathy 41

OMIM® : 57 Developmental and epileptic encephalopathy-41 (DEE41) is a neurologic disorder characterized by the onset of seizures in the first days or weeks of life. Affected infants show severely impaired psychomotor development with hypotonia, spasticity, lack of speech, poor visual fixation, feeding difficulties sometimes necessitating tube feeding, poor overall growth and microcephaly, and contractures. Brain imaging may show delayed myelination, thin corpus callosum, and cerebral atrophy (summary by the EPI4K Consortium, 2016). For a general phenotypic description and a discussion of genetic heterogeneity of DEE, see 308350. (617105) (Updated 05-Mar-2021)

MalaCards based summary : Developmental and Epileptic Encephalopathy 41, is also known as epileptic encephalopathy, early infantile, 41. An important gene associated with Developmental and Epileptic Encephalopathy 41 is SLC1A2 (Solute Carrier Family 1 Member 2). Related phenotypes are spasticity and developmental regression

Disease Ontology : 12 A developmental and epileptic encephalopathy characterized by onset in the first days or weeks of life of seizures, severely impaired psychomotor development, and brain anomalies including delayed myelination, thin corpus callosum, and cerebral atrophy that has material basis in heterozygous mutation in the SLC1A2 gene on chromosome 11p13.

UniProtKB/Swiss-Prot : 73 Epileptic encephalopathy, early infantile, 41: 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. EIEE41 inheritance is autosomal dominant.
