To identify susceptibility loci for schizophrenia, we performed a two-stage genome-wide association study (GWAS) of schizophrenia in the Han Chinese population (GWAS: 746 individuals with schizophrenia and 1,599 healthy controls; validation: 4,027 individuals with schizophrenia and 5,603 healthy controls). We identified two susceptibility loci for(More)
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(More)
Several lines of evidence suggest that efficient information integration between brain regions is disrupted in schizophrenia. Abnormalities in white matter tracts that interconnect brain regions may be directly relevant to this pathophysiological process. As a complex mental disorder with high heritability, mapping abnormalities in patients and their(More)
Numerous single nucleotide polymorphisms (SNPs) associated with complex diseases have been identified by genome-wide association studies (GWAS) and expression quantitative trait loci (eQTLs) studies. However, few of these SNPs have explicit biological functions. Recent studies indicated that the SNPs within the 3’UTR regions of susceptibility genes could(More)
To explore the effect of G72/G30 polymorphisms on the clinical manifestations of schizophrenia, especially on the age at onset and sex of patients, we examined three single nucleotide polymorphisms in 216 schizophrenic patients and 321 healthy controls. Significant associations of schizophrenia with the A allele of rs947267 (P=0.012) and haplotype A-A-G(More)
Autism is a pervasive neurodevelopmental disorder, with a significant role of genetic factors in its development. The neuropilin-2 (NRP2) gene is localized to 2q34, an autism susceptibility locus. NRP2 has been demonstrated to both guide axons and to control neuronal migration in the central nervous system. It has been reported that NRP2 may be required in(More)
The present study examined the correlation between variants in the d-amino acid oxidase activator (DAOA) locus and clinical symptoms and response to antipsychotics in schizophrenia. Case-control analysis and the family-based association test (FBAT) were performed to investigate whether four single nucleotide polymorphisms (SNPs) at DAOA gene are associated(More)
Disrupted-in-Schizophrenia-1 (DISC1) is located on 1q42.1, one of the most promising susceptibility loci in schizophrenia linkage studies. A non-synonymous genetic variation rs821616 (Ser704Cys) in DISC1, has recently been shown to be associated with schizophrenia in family-based study [Callicott et al. (2005); Proc Natl Acad Sci USA 102: 8627-8632]. In(More)
BACKGROUND Autism, a heterogeneous disease, is described as a genetic psychiatry disorder. Recently, abnormalities at the synapse are supposed to be important for the etiology of autism.SHANK3 (SH3 and multiple ankyrin repeat domains protein) gene encodes a master synaptic scaffolding protein at postsynaptic density (PSD) of excitatory synapse.
