Abstract:

Developmental and epileptic encephalopathy (DEE) is a clinically and genetically heterogeneous group of age-dependent neurological disorders characterized by onset of refractory seizures in infancy or early childhood and affected individuals with delayed or regressive psychomotor development. With the development of next-generation sequencing technology, especially the application of whole-exome sequencing technology, more and more genes have been found to be associated with DEE.These discoveries provide a basis for the detection of pathogenic genes for DEE in clinical work, and also help to deepen our understanding of the pathogenesis of DEE. In this review, we provide a comprehensive review of the genetic etiology, diagnosis and treatment of DEE, in order to assist clinicians in early identification of relevant gene mutations, thereby expediting disease diagnosis and timely implementation of optimal treatment.

Key words: genetic variation, DEE, OMIM database
