Variants in brain-related genes with a low NSS score confer significantly higher susceptibility than variants in other brain-related genes. The enrichment is strongest for schizophrenia, but we cannot rule out enrichment for other phenotypes. The false discovery rate conditional on the evolutionary proxy points to 27 candidate schizophrenia susceptibility loci, 12 of which are associated with schizophrenia and other psychiatric disorders or linked to brain development. Conclusions: Our results suggest that there is a polygenic overlap between schizophrenia and NSS score, a marker of human evolution, which is in line with the hypothesis that the persistence of schizophrenia is related to the evolutionary process of becoming human.]]> Wed 12 Aug 2020 09:42:59 AEST ]]> Genome-wide association study identifies five new schizophrenia loci https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:14264 −11) was with rs1625579 within an intron of a putative primary transcript for MIR137 (microRNA 137), a known regulator of neuronal development. Four other schizophrenia loci achieving genome-wide significance contain predicted targets of MIR137, suggesting MIR137-mediated dysregulation as a previously unknown etiologic mechanism in schizophrenia. In a joint analysis with a bipolar disorder sample (16,374 affected individuals and 14,044 controls), three loci reached genome-wide significance: CACNA1C (rs4765905, P = 7.0 × 10−9), ANK3 (rs10994359, P = 2.5 × 10−8) and the ITIH3-ITIH4 region (rs2239547, P = 7.8 × 10−9).]]> Wed 11 Apr 2018 18:45:05 AEST ]]> Leveraging genomic annotations and pleiotropic enrichment for improved replication rates in schizophrenia GWAS https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:26719 -8). There were 693 and 219 independent loci with model-based replication rates ≥80% and ≥90%, respectively. Compared to analyses not incorporating relative enrichment scores, CM3 increased out-of-sample yield for SNPs that replicate at a given rate. This demonstrates that replication probabilities can be more accurately estimated using prior enrichment information with CM3.]]> Wed 11 Apr 2018 17:05:48 AEST ]]> Expression analysis in a rat psychosis model identifies novel candidate genes validated in a large case-control sample of schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:23292 Wed 11 Apr 2018 15:09:07 AEST ]]> No reliable association between runs of homozygosity and schizophrenia in a well-powered replication study https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:27630 Froh and schizophrenia (β = 4.86,CI(β) = [0.90,8.83],Z = 2.40,p = 0.02). Since Keller et al. (2012), several studies reported inconsistent association of ROH burden with complex traits, particularly in case-control data. These conflicting results might suggest that the effects of autozygosity are confounded by various factors, such as socioeconomic status, education, urbanicity, and religiosity, which may be associated with both real inbreeding and the outcome measures of interest.]]> Wed 11 Apr 2018 14:15:34 AEST ]]> Application of the audio recorded cognitive screen and its relation to functioning in schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:28274 2(1)=7.16, p=0.007]. Conclusion: The ARCS may be sensitive to the cognitive deficits in outpatients with schizophrenia and an indicator of functional outcomes in this population.]]> Wed 11 Apr 2018 13:05:57 AEST ]]> Genetic correlation between amyotrophic lateral sclerosis and schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:34119 -4) with schizophrenia polygenic risk scores explaining up to 0.12% of the variance in ALS (P=8.4 × 10-7). A modest increase in comorbidity of ALS and schizophrenia is expected given these findings (odds ratio 1.08-1.26) but this would require very large studies to observe epidemiologically. We identify five potential novel ALS-associated loci using conditional false discovery rate analysis. It is likely that shared neurobiological mechanisms between these two disorders will engender novel hypotheses in future preclinical and clinical studies.]]> Wed 04 Sep 2019 09:40:14 AEST ]]> Transcriptome-wide association study of schizophrenia and chromatin activity yields mechanistic disease insights https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:50043 Thu 29 Jun 2023 14:38:49 AEST ]]> Genomic Dissection of Bipolar Disorder and Schizophrenia, Including 28 Subphenotypes https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:47202 Thu 15 Dec 2022 11:18:18 AEDT ]]> A polygenic resilience score moderates the genetic risk for schizophrenia: Replication in 18,090 cases and 28,114 controls from the Psychiatric Genomics Consortium https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:54811 Thu 14 Mar 2024 14:24:56 AEDT ]]> Aggression and trauma experiences among carer-relatives of people with psychosis https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:7405 Sat 24 Mar 2018 08:42:43 AEDT ]]> Emotional face processing in schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:8286 Sat 24 Mar 2018 08:40:28 AEDT ]]> Brief neuropsychological profiles in psychosis: a pilot study using the Audio Recorded Cognitive Screen (ARCS) https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:10315 Sat 24 Mar 2018 08:07:00 AEDT ]]> Divergent patterns of social cognition performance in autism and 22q11.2 deletion syndrome (22q11DS) https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:20081 Sat 24 Mar 2018 08:00:08 AEDT ]]> Biological insights from 108 schizophrenia-associated genetic loci https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:21465 DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses. Independent of genes expressed in brain, associations were enriched among genes expressed in tissues that have important roles in immunity, providing support for the speculated link between the immune system and schizophrenia.]]> Sat 24 Mar 2018 07:52:31 AEDT ]]> Genetic influences on schizophrenia and subcortical brain volumes: large-scale proof of concept https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:29335 Sat 24 Mar 2018 07:34:19 AEDT ]]> LD score regression distinguishes confounding from polygenicity in genome-wide association studies https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:28311 Sat 24 Mar 2018 07:27:06 AEDT ]]> Contrasting genetic architectures of schizophrenia and other complex diseases using fast variance-components analysis https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:23305 Sat 24 Mar 2018 07:16:19 AEDT ]]> Partitioning heritability by functional annotation using genome-wide association summary statistics https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:23306 Sat 24 Mar 2018 07:16:19 AEDT ]]> Relationship between childhood adversity and clinical and cognitive features in schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:22081 Sat 24 Mar 2018 07:15:15 AEDT ]]> Gene expression imputation across multiple brain regions provides insights into schizophrenia risk https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:47780 Mon 30 Jan 2023 10:58:57 AEDT ]]> The role of polygenic risk score gene-set analysis in the context of the omnigenic model of schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:42338 N = 29,125 cases and 34,836 controls), a robust polygenic signal was observed from gene sets based on TCF4, FMR1, upregulation from MIR137 and downregulation from CHD8. Additional analyses revealed a constant floor effect in the amount of variance explained, consistent with the omnigenic model. Thus, we report that putative core gene sets showed a significant effect above and beyond the floor effect that might be linked with the underlying omnigenic background. In addition, we demonstrate a method to quantify the contribution of specific gene sets within the omnigenic context.]]> Mon 22 Aug 2022 14:00:20 AEST ]]> A polygenic resilience score moderates the genetic risk for schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:38229 Mon 16 Aug 2021 17:39:39 AEST ]]> Large-scale analysis of structural brain asymmetries in schizophrenia via the ENIGMA consortium https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:50977 Mon 14 Aug 2023 15:24:38 AEST ]]> Schizophrenia risk conferred by rare protein-truncating variants is conserved across diverse human populations https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:50972 Mon 14 Aug 2023 15:19:39 AEST ]]> Age at first birth in women is genetically associated with increased risk of schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:43035 Mon 12 Sep 2022 11:49:25 AEST ]]> Mapping genomic loci implicates genes and synaptic biology in schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:49672 Fri 26 May 2023 15:35:47 AEST ]]> Population-based identity-by-descent mapping combined with exome sequencing to detect rare risk variants for schizophrenia https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:42186 n = 3,473) by performing identity-by-descent (IBD) mapping followed by exome sequencing of individuals identified as sharing risk haplotypes to search for rare risk variants in coding regions. We identified 45 rare haplotypes (>1 cM) that were significantly more common in cases than controls. By exome sequencing 105 haplotype carriers, we investigated these haplotypes for functional coding variants that could be tested for association in independent GWAS samples. We identified one rare missense variant in PCNT but did not find statistical support for an association with schizophrenia in a replication analysis. However, IBD mapping can prioritize both individual samples and genomic regions for follow-up analysis but genome rather than exome sequencing may be more effective at detecting risk variants on rare haplotypes.]]> Fri 26 Aug 2022 10:49:17 AEST ]]> Genomic relationships, novel loci, and pleiotropic mechanisms across eight psychiatric disorders https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:46603 Fri 25 Nov 2022 16:41:41 AEDT ]]> A Comparison of Ten Polygenic Score Methods for Psychiatric Disorders Applied Across Multiple Cohorts https://novaprd-lb.newcastle.edu.au/vital/access/manager/Repository/uon:48644 Fri 24 Mar 2023 13:44:42 AEDT ]]>
