Further, the gene set analyses revealed several miRNAs regulating schizophrenia risk genes, with the strongest enrichment for targets of miR-9-5p (P = .0056 for enrichment among the top 1% most-associated single-nucleotide polymorphisms, corrected for multiple testing). It is further of note that MIR9-2 is located in a genomic region showing strong evidence for association with schizophrenia (P = 7.1 × 10−8). The second and third strongest gene set signals were seen for the targets of miR-485-5p and miR-137, respectively. Conclusions and Relevance: This study provides evidence for a role of miR-9-5p in the etiology of schizophrenia. Its implication is of particular interest as the functions of this neurodevelopmental miRNA tie in with established disease biology: it has a regulatory loop with the fragile X mental retardation homologue FXR1 and regulates dopamine D2 receptor density.]]> Wed 11 Apr 2018 15:28:50 AEST ]]> Evidence for genetic overlap between schizophrenia and age at first birth in women. https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29862 2 = 1.1E-03, P = 4.1E-04), reflecting the published relationship between maternal age and SCZ risk in offspring by McGrath et al in 2014. Conclusions and Relevance: This study provides evidence for a significant overlap between genetic factors associated with risk of SCZ and genetic factors associated with AFB. It has been reported that SCZ risk associated with increased maternal age is explained by the age of the father and that de novo mutations that occur more frequently in the germline of older men are the underlying causal mechanism. This explanation may need to be revised if, as suggested herein and if replicated in future studies, there is also increased genetic risk of SCZ in older mothers.]]> Sat 24 Mar 2018 07:40:47 AEDT ]]> Genetic influences on schizophrenia and subcortical brain volumes: large-scale proof of concept https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29335 Sat 24 Mar 2018 07:34:19 AEDT ]]>
