Abstract:
Schizophrenia is a severe psychiatric disorder characterizedby a complex mode of inheritance. Forebrain-specific CNB knockoutmice display a spectrum of behavioral abnormalities relatedto altered behaviors observed in schizophrenia patients. Toexamine whether calcineurin dysfunction is involved in schizophreniaetiology, we undertook studies of an initial subset of calcineurin-relatedgenes, prioritizing ones that map to loci previously implicatedin schizophrenia by linkage studies. Transmission disequilibrium studies in a large sample of affected families detected associationof the PPP3CC gene, which encodes the calcineurin catalyticsubunit, with disease. Our results identify PPP3CC, locatedat 8p21.3, as a potential schizophrenia susceptibility geneand support the proposal that alterations in calcineurin signalingcontribute to schizophrenia pathogenesis.
