  • Genome-wide association meta-analysis of 78,308 individuals identifies new loci and genes influencing human intelligence - Unknown journal (n.d.) · Unknown authors · PubMed 28530673

    [INTRO] Intelligence is associated with important economic and health-related life outcomes. Despite substantial heritability (0.54) and confirmed polygenic nature, initial genetic studies were mostly underpowered. Here we report a meta-analysis for intelligence of 78,308 individuals. We identify 336 single nucleotide polymorphisms (SNPs) (METAL P<5×10−8) in 18 genomic loci, of which 15 are novel. Roughly half are located inside a gene, implicating 22 genes, of which 11 are novel findings. Gene-based analyses identified an additional 30 genes (MAGMA P<2.73×10−6), of which all but one have not been implicated previously. We show that identified genes are predominantly expressed in brain tissue, and pathway analysis indicates the involvement of genes regulating cell development (MAGMA

  • Biological annotation of genetic loci associated with intelligence in a meta-analysis of 87 740 individuals - Unknown journal (n.d.) · Unknown authors · PubMed 29520040

    ABSTRACT: Variance in IQ is associated with a wide range of health outcomes, and 1% of the population are affected by intellectual disability. Despite a century of research, the fundamental neural underpinnings of intelligence remain unclear. We integrate results from genome-wide association studies (GWAS) of intelligence with brain tissue and single cell gene expression data to identify tissues and cell types associated with intelligence. GWAS data for IQ (N = 78 308) were meta-analyzed with a study comparing 1 247 individuals with mean IQ ~170 to 8 185 controls. Genes associated with intelligence implicate pyramidal neurons of the somatosensory cortex and CA1 region of the hippocampus, and midbrain embryonic GABAergic neurons. Tissue-specific analyses find the most significant enrichment

  • Large-scale Cognitive GWAS Meta-Analysis Reveals Tissue-Specific Neural Expression and Potential Nootropic Drug Targets - Unknown journal (n.d.) · Unknown authors · PubMed 29186694

    ABSTRACT: Summary Here, we present a large (N=107,207) genome-wide association study (GWAS) of general cognitive ability (g), further enhanced by combining results with a large-scale GWAS of educational attainment. We identified 70 independent genomic loci associated with GCA. Results showed significant enrichment for genes causing Mendelian disorders with an intellectual disability phenotype. Competitive pathway analysis implicated the biological processes of neurogenesis and synaptic regulation, as well as the gene targets of two pharmacologic agents: cinnarizine, a T-type calcium channel blocker; and LY97241, a potassium channel inhibitor. Transcriptome-wide and epigenome-wide analysis revealed that the implicated loci were enriched for genes expressed across all brain regions (most str

  • A combined analysis of genetically correlated traits identifies 187 loci and a role for neurogenesis and myelination in intelligence - Unknown journal (n.d.) · Unknown authors · PubMed 29326435

    ABSTRACT: Intelligence, or general cognitive function, is phenotypically and genetically correlated with many traits, including a wide range of physical, and mental health variables. Education is strongly genetically correlated with intelligence (rg = 0.70). We used these findings as foundations for our use of a novel approach-multi-trait analysis of genome-wide association studies (MTAG; Turley et al. 2017)-to combine two large genome-wide association studies (GWASs) of education and intelligence, increasing statistical power and resulting in the largest GWAS of intelligence yet reported. Our study had four goals: first, to facilitate the discovery of new genetic loci associated with intelligence; second, to add to our understanding of the biology of intelligence differences; thir
