To date, GWASs on schizophrenia have identified several genome-wide significant associated variants located in the zinc finger protein 804A (ZNF804A), neurogranin (NRGN), transcription factor 4 (TCF4) genes and a major histocompatibility complex (MHC) region [3,4]. The gene discussed is ZNF804A; the disease is schizophrenia.
