This includes genes associated with the most common “classical” PMEs (e.g. Unverricht‐Lundborg disease (CSTB), Lafora disease (EPM2A, NHLRC1), neuronal ceroid lipofuscinoses (TPP1, DNAJC5, CLN5, CLN6) and myoclonic epilepsy with ragged red fibres (MT-TK)), rarer PME genes reported in only a small number of individuals, and genes typically associated with other epilepsy phenotypes but where PME phenotypes have also been reported (e.g. CHD2) [77–79]. Here, DNAJC5 is linked to progressive myoclonus epilepsy.
