We sought to detect rearrangements affecting DISC 1 in 347 individuals meeting the DSM3R criteria for schizophrenia or schizoaffective disorder, 70 subjects with bipolar disorder and 377 psychiatrically healthy controls, but failed to detect any pathological rearrangement.
Based on the genetic and functional evidence that DISC1 may be associated with schizophrenia, we sequenced portions of DISC1 in 28 unrelated probands with schizophrenia and six unrelated probands with schizoaffective disorder, ascertained as part of a large sibpair study.
The phenotype associated with DISC1 in the t (1;11) translocation family includes schizophrenia, schizoaffective disorder, recurrent major depression and bipolar disorder.
The Disrupted in Schizophrenia 1 (DISC1) gene has been associated with the risk of schizophrenia, schizoaffective disorder, bipolar disorder, major depression, autism, and Asperger syndrome in different populations.
Disrupted in schizophrenia 1 (DISC1) has been associated with risk of schizophrenia, schizoaffective disorder, bipolar disorder, major depression, autism and Asperger syndrome, but apart from in the original translocation family, true causal variants have yet to be confirmed.
Genomewide linkage scan in schizoaffective disorder: significant evidence for linkage at 1q42 close to DISC1, and suggestive evidence at 22q11 and 19p13.
These findings implicate DISC1 in variation of prefrontal cortical volume and positive symptoms, thus providing a potential mechanism through which DISC1 may confer increased risk for schizophrenia or schizoaffective disorder.
