PTPRZ1 and epilepsy: Over-representation analysis of genes that are deleted in both GGE and RE together (134 genes) showed significant over-representation (empirical p-value = 0.012) of epilepsy-associated genes (APBA2, CHRNA7, CNTNAP2, F5, GABRA5, GABRB3, GRIN2A, KCNQ1, MT1E, PTPRZ1, SCN1A, SGCG, SSTR4).
