OBJECTIVE Neuregulin-1 (NRG1) has been put forward as a susceptibility gene for schizophrenia. We investigated the association between Neuregulin-1 and the P300 wave, a schizophrenia endophenotype. METHODS Participants were 64 patients with DSM-IV schizophrenia or schizoaffective disorder, 97 of their non psychotic relatives and 35 unrelated controls. The P300 wave was extracted from the elec...

BACKGROUND Neuregulin1 (NRG1) influences the development of white matter connectivity and is implicated in genetic susceptibility to schizophrenia. The cingulum bundle is a white matter structure implicated in schizophrenia. Its anterior component is especially implicated, as it provides reciprocal connections between brain regions with prominent involvement in the disorder. Abnormalities in th...

schizophrenia is a severe neuropsychiatric disorder with symptoms such as hallucination, delusion and mental disorder. it is a complex disorder, in which genetic components play a crucial role in its pathogenesis. among candidate genes for schizophrenia, neuregulin 1 (nrg1) gene is the most important gene,  association of which with the illness has been confirmed in several studies. single nucl...

D ata from twin, family, and adoption studies provide strong evidence that genetic factors play a major aetiological role in schizophrenia. By a series of linkage studies, chromosome 8p has been implicated as a region harbouring a schizophrenia susceptibility gene. Recently, Stefansson and colleagues reported that neuregulin 1 (NRG1), located in 8p21-12, may be involved in the aetiology of schi...

The neuregulin 1 (NRG1) gene has been the subject of considerable excitement within the psychiatric genetics literature since it was originally identified as a potential susceptibility locus for schizophrenia. Here we provide an update of our first meta-analysis of this association. Case-control and family-based genetic association studies of the NRG1 gene in healthy control groups and clinical...
