Summary

Developmental and epileptic encephalopathy-3 (DEE3) is an autosomal recessive neurologic disorder characterized by onset of refractory seizures in the first weeks to months of life. The prognosis is poor, and affected children either may die within 1 to 2 years after birth or survive in a persistent vegetative state. The EEG pattern often shows a suppression-burst pattern with high-voltage bursts of slow waves mixed with multifocal spikes alternating with isoelectric suppression phases; these features are reminiscent of a clinical diagnosis of Ohtahara syndrome. Some patients may have hypsarrhythmia on EEG, consistent with a clinical diagnosis of West syndrome (summary by Molinari et al., 2005, Molinari et al., 2009). For a discussion of genetic heterogeneity of DEE, see 308350. [from OMIM]
