title = "Effects of gene dosage on cognitive ability: A function-based association study across brain and non-brain processes",
abstract = "Genomic Copy Number Variants (CNVs) that increase risk for neurodevelopmental disorders are also associated with lower cognition. Most studies have focused on the most frequently recurrent CNVs. However, it has been difficult to investigate ultra-rare CNVs and as a result, we have a limited understanding of the full range of gene-dosage-sensitive biological processes linked to cognitive ability. We performed GWAS and functional burden analyses across tissues, cell-types, and ontologies to test the association between all rare CNVs and cognitive ability in 258,292 individuals. We identified a novel association of a duplication at 2q12.3 with higher performance in cognitive ability. Functional burden tests performed on 6,502 gene sets identified 864 gene-sets associated with cognition. The effects-sizes of deletion and duplication were negatively correlated, suggesting that functions across all levels of biological observations were either sensitive to deletion (e.g. subcortical and postsynaptic functions.) or duplication (e.g. cerebral cortex and presynaptic functions). Associations between non-brain tissue and cognition were driven in part by genes under constraint with lower tissue specificity. The latter may help investigate medical comorbidities observed in neurodevelopmental and psychiatric disorders.",
