KCNH8 and schizophrenia: We find dysregulated expression not only as previously reported for the Na + channels SCN2A and SCN3A and the K + channels KCNB1 and ATP1B1, but also for additional channel types not previously implicated in schizophrenia (e.g., SLC4A4, SLC32A1, SLC13A4, SLC1A4, SLC6A1, KCNK10, KCNH8, KCTD2).
