Bioinformatics analyses imply that genes near SNPs associated with general risk tolerance are highly expressed in brain tissues and point to a role for glutamatergic and GABAergic neurotransmission. We found no evidence of enrichment for genes previously hypothesized to relate to risk tolerance.]]> Wed 25 Jan 2023 14:39:42 AEDT ]]> Genetic analysis of over 1 million people identifies 535 new loci associated with blood pressure traits https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44073 Wed 22 Mar 2023 15:46:47 AEDT ]]> The genetic architecture of the human cerebral cortex https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42676 Wed 22 Mar 2023 14:34:07 AEDT ]]> Genome-wide analyses of individual differences in quantitatively assessed reading- and language-related skills in up to 34,000 people https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51038 P = 1.098 × 10-8) at a locus that has not been associated with intelligence or educational attainment. All five reading-/language-related traits showed robust SNP heritability, accounting for 13 to 26% of trait variability. Genomic structural equation modeling revealed a shared genetic factor explaining most of the variation in word/nonword reading, spelling, and phoneme awareness, which only partially overlapped with genetic variation contributing to nonword repetition, intelligence, and educational attainment. A multivariate GWAS of word/nonword reading, spelling, and phoneme awareness maximized power for follow-up investigation. Genetic correlation analysis with neuroimaging traits identified an association with the surface area of the banks of the left superior temporal sulcus, a brain region linked to the processing of spoken and written language. Heritability was enriched for genomic elements regulating gene expression in the fetal brain and in chromosomal regions that are depleted of Neanderthal variants. Together, these results provide avenues for deciphering the biological underpinnings of uniquely human traits.]]> Wed 16 Aug 2023 10:23:55 AEST ]]> Sex-Dependent Shared and Nonshared Genetic Architecture Across Mood and Psychotic Disorders https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44746 Tue 21 Mar 2023 16:53:58 AEDT ]]> Discovery of 42 genome-wide significant loci associated with dyslexia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53505 Thu 30 Nov 2023 15:57:26 AEDT ]]> Language and reading impairments are associated with increased prevalence of non-right-handedness https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50974 Mon 14 Aug 2023 15:18:04 AEST ]]> Genome-wide Association Meta-analysis of Childhood and Adolescent Internalizing Symptoms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50952 overall) detected no genome-wide significant hits and showed low single nucleotide polymorphism (SNP) heritability (1.66%, 95% CI = 0.84-2.48%, neffective = 132,260). Stratified analyses indicated rater-based heterogeneity in genetic effects, with self-reported internalizing symptoms showing the highest heritability (5.63%, 95% CI = 3.08%-8.18%). The contribution of additive genetic effects on internalizing symptoms appeared to be stable over age, with overlapping estimates of SNP heritability from early childhood to adolescence. Genetic correlations were observed with adult anxiety, depression, and the well-being spectrum (|rg| > 0.70), as well as with insomnia, loneliness, attention-deficit/hyperactivity disorder, autism, and childhood aggression (range |rg| = 0.42-0.60), whereas there were no robust associations with schizophrenia, bipolar disorder, obsessive-compulsive disorder, or anorexia nervosa. Conclusion: Genetic correlations indicate that childhood and adolescent internalizing symptoms share substantial genetic vulnerabilities with adult internalizing disorders and other childhood psychiatric traits, which could partially explain both the persistence of internalizing symptoms over time and the high comorbidity among childhood psychiatric traits. Reducing phenotypic heterogeneity in childhood samples will be key in paving the way to future GWAS success.]]> Mon 14 Aug 2023 14:36:09 AEST ]]> A Genome-Wide Association Study of Total Child Psychiatric Problems Scores https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50392 0.49), but not with autism or the less common adult disorders (schizophrenia, bipolar disorder, or eating disorders) (rG < 0.01). Importantly, the total psychiatric problem score also showed at least a moderate genetic correlation with intelligence, educational attainment, wellbeing, smoking, and body fat (rG > 0.29). The results suggest that many common genetic variants are associated with childhood psychiatric symptoms and related phenotypes in general instead of with specific symptoms. Further research is needed to establish causality and pleiotropic mechanisms between related traits.]]> Mon 13 May 2024 11:16:33 AEST ]]> Novel loci for childhood body mass index and shared heritability with adult cardiometabolic traits https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41815 Fri 12 Aug 2022 12:45:25 AEST ]]> Genetic association study of childhood aggression across raters, instruments, and age https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39716 Fri 02 Jun 2023 09:38:38 AEST ]]>
