We resequenced the exonic regions of DLGAP3 gene, which encodes SAP90/PSD95-associated protein 3, in 215 schizophrenic patients and 215 non-psychotic controls. Seven known single-nucleotide polymorphisms (SNPs) were identified, but not associated with schizophrenia. Nevertheless, we identified several rare missense mutations and some of them might be associated with the pathogenesis of schizophrenia.
