Abstract
Recurrent mutations at Arg1617 and Arg1872 lead to elevated Nav1.6 channel activity by impairing channel inactivation. Channel hyperactivity is the major pathogenic mechanism for gain-of-function mutations of SCN8A. EIEE13 differs mechanistically from Dravet syndrome, which is caused by loss-of-function mutations of SCN1A. This distinction has important consequences for selection of antiepileptic drugs and the development of gene- and mutation-specific treatments.
