NAPB and developmental and epileptic encephalopathy: Description of the electroclinical profile associated with a novel pathogenic variant

ABSTRACT

Developmental and epileptic encephalopathies (DEE) are a group of neurodevelopmental disorders characterized by epileptic seizures associated with developmental delay or regression. DEE are genetically heterogeneous, and the proteins involved play roles in multiple pathways such as synaptic transmission, metabolism, neuronal development or maturation, transcriptional regulation, and intracellular trafficking. We performed whole exome sequencing on a consanguineous family with three children presenting an early onset (
