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 ]]> No reliable association between runs of homozygosity and schizophrenia in a well-powered replication study https://nova.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 ]]> Genetic correlation between amyotrophic lateral sclerosis and schizophrenia https://nova.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 ]]> Cross-disorder analysis of schizophrenia and 19 immune-mediated diseases identifies shared genetic risk https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46890 Tue 06 Dec 2022 12:02:52 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://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54811 Thu 14 Mar 2024 14:24:56 AEDT ]]> Genome-wide association study reveals greater polygenic loading for schizophrenia in cases with a family history of illness https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29641 Sat 24 Mar 2018 07:41:54 AEDT ]]> Schizophrenia risk from complex variation of complement component 4 https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30050 Sat 24 Mar 2018 07:31:15 AEDT ]]> LD score regression distinguishes confounding from polygenicity in genome-wide association studies https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28311 Sat 24 Mar 2018 07:27:06 AEDT ]]> Modeling linkage disequilibrium increases accuracy of polygenic risk scores https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23379 2 increased from 20.1% to 25.3% in a large schizophrenia dataset and from 9.8% to 12.0% in a large multiple sclerosis dataset.
