Epileptic Encephalopathy, Infantile Or Early Childhood; Iecee

Description

IECEE is a neurodevelopmental disorder characterized by delayed psychomotor development apparent in infancy and resulting in severe to profound intellectual disability with poor or absent speech. Most patients never achieve independent walking. Patients typically have onset of refractory multifocal seizures between the first weeks and years of life, and some may show developmental regression. Additional features, such as hypotonia and cortical visual impairment, are more variable (summary by Myers et al., 2017).
