Other monogenic epilepsies for which a molecular diagnosis may influence the choice of anti-epileptic drugs are KCNQ2-related epilepsies and the use of ezogabine [83, 84], SCN1A-related Dravet syndrome and the use of clemizole [85], and DEPDC5 and the use of the rapamycin derivative everolimus, which has already been effective in early clinical trials [86]. Here, SCN1A is linked to encephalopathy, progressive, early-onset, with brain edema and/or leukoencephalopathy.
