Abstract
Three common variants of NPAS3, also found in controls, showed a positive association with schizophrenia (NM_001164749: rs12434716, c.1654G>C, p = 0.009; rs10141940, c.2208C>T, p = 0.01; rs10142034, c.2262C>G, p = 0.01). The c.1654G>C variant, results in an p.Ala552Pro change and may affect NPAS3 protein function directly. Alternatively, the three SNPs may affect the splicing of NPAS3 transcripts, as they are each located within putative exonic splicing enhancer (ESE) motifs (ESEFinder). A c.726C>T variant, identified in three patients, is located in an ESE element and is predicted to reduce the function of the motif. Other variants, identified in controls, included c.2089G>A (p.Gly697Ser) and c.2097T>C. Our identification of potentially defective NPAS3 variants supports recent studies that implicate perturbations in NPAS3 pathways in impaired neurogenesis and psychosis.
