GRIN1 and schizophrenia: Similarly, this study identified DMP- and DMR-overlapping genes integral to synaptic vesicle exocytosis, presynapse, excitatory postsynaptic potential, regulation of neurotransmitter secretion, neurotransmitter transmembrane transporter activity (e.g., GRIN1, TUBB3, CPLX1, CYP46A1) and risk for schizophrenia (e.g., DLGAP2, EHMT1, CPLX1, GRIN1).
