ABSTRACT
One of the important causes of developmental epileptic encephalopathy (DEE) is the mutation of ion channel genes, including the mutation of the CACNA1E gene. CACNA1E-related DEE cases were first reported in 2018.The mutation types include new missense mutations, nonsense mutations and frameshift mutations, but the correlation between mutation sites and types with the phenotype of DEE is not clear.This review aims to summarize the reported CACNA1E-related DEE cases, and explore the correlation between the clinical phenotype of CACNA1E-related DEE and gene mutation sites and mutation types.Meanwhile, possible pathogenesis of CACNA1E-related DEE and the progress of drug intervention were reviewed to provide references for the diagnosis and precise treatment of DEE.
