  • Gene-level analysis reveals the genetic aetiology and therapeutic targets of schizophrenia. - Nature human behaviour (2025) · Dang X, Teng Z, Yang Y, Li W, Liu J, Hui L, Zhou D, Gong D, Dai SS, Li Y, Li X, Lv L, Zeng Y, Yuan Y, Ma X, Liu Z, Li T, Luo XJ · PubMed 39753749

    Genome-wide association studies (GWASs) have reported multiple risk loci for schizophrenia (SCZ). However, the majority of the associations were from populations of European ancestry. Here we conducted a large-scale GWAS in Eastern Asian populations (29,519 cases and 44,392 controls) and identified ten Eastern Asian-specific risk loci, two of which have not been previously reported. A further cross-ancestry GWAS meta-analysis (96,806 cases and 492,818 controls) including populations from diverse ancestries identified 61 previously unreported risk loci. Systematic variant-level analysis, including fine mapping, functional genomics and expression quantitative trait loci, prioritized potential causal variants. Gene-level analyses, including transcriptome-wide association study, proteome-wide

  • Association of Schizophrenia Risk With Disordered Niacin Metabolism in an Indian Genome-wide Association Study. - JAMA psychiatry (2021) · Periyasamy S, John S, Padmavati R, Rajendren P, Thirunavukkarasu P, Gratten J, Vinkhuyzen A, McRae A, Holliday EG, Nyholt DR, Nancarrow D, Bakshi A, Hemani G, Nertney D, Smith H, Filippich C, Patel K, Fowdar J, McLean D, Tirupati S, Nagasundaram A, Gundugurti PR, Selvaraj K, Jegadeesan J, Jorde LB, Wray NR, Brown MA, Suetani R, Giacomotto J, Thara R, Mowry BJ · PubMed 31268507

    Genome-wide association studies (GWASs) in European populations have identified more than 100 schizophrenia-associated loci. A schizophrenia GWAS in a unique Indian population offers novel findings. To discover and functionally evaluate genetic loci for schizophrenia in a GWAS of a unique Indian population. This GWAS included a sample of affected individuals, family members, and unrelated cases and controls. Three thousand ninety-two individuals were recruited and diagnostically ascertained via medical records, hospitals, clinics, and clinical networks in Chennai and surrounding regions. Affected participants fulfilled DSM-IV diagnostic criteria for schizophrenia. Unrelated control participants had no personal or family history of psychotic disorder. Recruitment, genotyping, and analysis o

  • Comparative genetic architectures of schizophrenia in East Asian and European populations - Unknown journal (n.d.) · Unknown authors · PubMed 31740837

    ABSTRACT: Schizophrenia is a debilitating psychiatric disorder with approximately 1% lifetime risk globally. Large-scale schizophrenia genetic studies have reported primarily on European ancestry samples, potentially missing important biological insights. Here, we report the largest study to date of East Asian participants (22,778 schizophrenia cases and 35,362 controls), identifying 21 genome-wide significant associations in 19 genetic loci. Common genetic variants that confer risk for schizophrenia have highly similar effects between East Asian and European ancestries (rg = 0.98 ± 0.03), indicating that the genetic basis of schizophrenia and its biology are broadly shared across populations. A fixed-effect meta-analysis including individuals from East Asian and European ancestries ident

  • Multi-trait analysis for genome-wide association study of five psychiatric disorders - Unknown journal (n.d.) · Unknown authors · PubMed 32606422

    ABSTRACT: We conducted a cross-trait meta-analysis of genome-wide association study on schizophrenia (SCZ) (n = 65,967), bipolar disorder (BD) (n = 41,653), autism spectrum disorder (ASD) (n = 46,350), attention deficit hyperactivity disorder (ADHD) (n = 55,374), and depression (DEP) (n = 688,809). After the meta-analysis, the number of genomic loci increased from 14 to 19 in ADHD, from 3 to 10 in ASD, from 45 to 57 in DEP, from 8 to 54 in BD, and from 64 to 87 in SCZ. We observed significant enrichment of overlapping genes among different disorders and identified a panel of cross-disorder genes. A total of seven genes were found being commonly associated with four out of five psychiatric conditions, namely GABBR1, GLT8D1, HIST1H1B, HIST1H2BN, HIST1H4L, KCNB1, and DCC.

  • Mapping genomic loci implicates genes and synaptic biology in schizophrenia - Unknown journal (n.d.) · Unknown authors · PubMed 35396580

    ABSTRACT: SUMMARY Schizophrenia has a heritability of 60-80%, much of which is attributable to common risk alleles. Here, in a 2-stage genome-wide association study of up to 76,755 people with schizophrenia and 243,649 controls, we report common variant associations at 287 distinct genomic loci. Associations were concentrated in genes expressed in CNS neurons, excitatory and inhibitory, but not other tissues or cell types. Using fine-mapping and functional genomic data, we identify 120 genes (106 protein-coding) as likely to underpin associations at some of these loci, including 16 genes with credible causal non-synonymous or UTR variation. We also implicate fundamental processes related to neuronal function, including synaptic organisation, differentiation, and transmission. Fine-mapped
