STXBP1 and epilepsy: However, other recent gene discoveries, including ALG13, EEF1A2, GNAO1, NECAP1, SNAP25, STX1B, STXBP1, PURA, and WWOX, highlight that epileptogenesis is caused by perturbations in diverse cellular pathways (Table 1), providing further evidence that epilepsy is not explained wholly as a channelopathy.
