Summaries for Epileptic Encephalopathy, Early Infantile, 81

OMIM : 56 Early infantile epileptic encephalopathy-81 (EIEE81) is an autosomal recessive neurodevelopmental disorder characterized by onset of severe refractory seizures soon after birth. Affected individuals show little developmental progress with no eye contact and no motor or cognitive development. Other features may include facial dysmorphism, such as hypotonic facies and epicanthal folds, as well as sensorineural hearing loss and peripheral neuropathy. Brain imaging shows cerebral atrophy, impaired myelination, thin corpus callosum, and progressive leukoencephalopathy (summary by Esposito et al., 2019). For a discussion of genetic heterogeneity of EIEE, see EIEE1 (308350). (618663)

MalaCards based summary : Epileptic Encephalopathy, Early Infantile, 81, is also known as eiee81. An important gene associated with Epileptic Encephalopathy, Early Infantile, 81 is DMXL2 (Dmx Like 2). Affiliated tissues include eye and brain.
