| Title | 成人的表情3 q13.31 microdeletion. |
| Abstract | The emerging 3q13.31 microdeletion syndrome appears to encompass diverse neurodevelopmental conditions. However, the 3q13.31 deletion is rare and few adult cases have yet been reported. We examined a cohort withschizophrenia(n?=?459) and adult control subjects (n?=?26,826) using high-resolution microarray technology for deletions and duplications at the 3q13.31 locus. We report on the extended adult phenotype associated with a 3q13.31 microdeletion in a 41-year-old male proband withschizophreniaand a nonverbal learning disability. He was noted to have a speech impairment, delayed motor skills, and other features consistent with the 3q13.31 microdeletion syndrome. The 2.06�Mb deletion overlapped two microRNAs and seven RefSeq genes, including GAP43,LSAMP, DRD3, and ZBTB20. No overlapping 3q13.31 deletions or duplications were identified in control subjects. Later-onset conditions likeschizophreniaare increasingly associated with rare copy number variations and associated genomic disorders like the 3q13.31 microdeletion syndrome. Detailed phenotype information across the lifespan facilitates genotype-phenotype correlations, accurate genetic counselling, and anticipatory care. |

| Title | Associations between polymorphisms of LSAMP gene and schizophrenia. |
| Abstract | The purpose of this study was to explore relationships between single-nucleotide polymorphisms (SNPs) in the limbic system-associated membrane protein (LSAMP) gene andschizophrenia. Twenty-two SNPs were analysed in 127 unrelatedschizophrenicpatients and in 171 healthy controls. The results showed significant allelic and haplotypic associations betweenLSAMPgene andschizophrenia. |

| Title | Polygenic associations of neurodevelopmental genes in suicide attempt. |
| Abstract | The risk for suicidal behavior (SB) is elevated inschizophrenia(SCZ), bipolar disorder (BPD) and major depressive disorder (MDD), but also occurs in subjects without psychiatric diagnoses. Genome-wide association studies (GWAS) on SB may help to understand this risk, but have been hampered by low power due to limited sample sizes, weakly ascertained SB or a reliance on single-nucleotide protein (SNP)-by-SNP analyses. Here, we tried to mitigate such issues with polygenic risk score (PRS) association tests combined with hypothesis-driven strategies using a family-based sample of 660 trios with a well-ascertained suicide attempt (SA) outcome in the offspring (Genetic Investigation of Suicide and SA, GISS). Two complementary sources of PRS information were used. First, a PRS that was discovered and validated in the GISS SA revealed the polygenic association of SNPs in 750 neurodevelopmental genes, which was driven by the SA phenotype, rather than the major psychiatric diagnoses. Second, a PRS based on three different genome-wide association studies (on SCZ, BPD or MDD) from the Psychiatric Genomics Consortium (PGC) showed an association of the PGC-SCZ PRS in the SA subjects with and without major psychiatric diagnoses. We characterized the PGC-SCZ overlap in the SA subjects without diagnoses. The extended major histocompatibility complex region did not contribute to the overlap, but we delineated the genic overlap to neurodevelopmental genes that partially overlapped with those identified by the GISS PRS. Among the 590 SA polygenes implicated here, there were several developmentally important functions (cell adhesion/migration, small GTPase and receptor tyrosine kinase signaling), and 16 of the SA polygenes have previously been studied in SB (BDNF, CDH10, CDH12, CDH13, CDH9, CREB1, DLK1, DLK2, EFEMP1, FOXN3, IL2,LSAMP, NCAM1, nerve growth factor (NGF), NTRK2 and TBC1D1). These novel genome-wide insights, supported by two lines of evidence, suggested the importance of a polygenic neurodevelopmental etiology in SB, even in the absence of major psychiatric diagnoses.Molecular Psychiatry advance online publication, 15 December 2015; doi:10.1038/mp.2015.187. |
