Genome-wide association studies (GWASs) have identified several susceptibility loci for bipolar disorder (BD) and shown that the genetic architecture of BD can be explained by polygenicity, with numerous variants contributing to BD. In present GWAS (Phase I/II), which included 2964 61 887 control subjects from Japanese population, we detected a novel locus at 11q12.2 (rs28456, P=6.4 × 10−9), region known contain regulatory genes plasma lipid levels (FADS1/2/3). A subsequent meta-analysis...

Genome-wide association studies (GWASs) have identified >100 susceptibility loci for schizophrenia (SCZ) and demonstrated that SCZ is a polygenic disorder determined by numerous genetic variants but with small effect size. We conducted GWAS in the Japanese (JPN) population (a) to detect novel SCZ-susceptibility genes (b) examine shared risk of across (East Asian [EAS] European [EUR]) populations and/or trans-diseases (SCZ, bipolar [BD], major depressive [MDD]) within EAS between EUR...

Abstract Large-scale genome-wide association studies (GWASs) on bipolar disorder (BD) have implicated the involvement of fatty acid desaturase ( FADS ) locus. These enzymes (FADS1 and FADS2) are involved in metabolism eicosapentaenoic (EPA) docosahexaenoic (DHA), which thought to potentially benefit patients with mood disorders. To model reductions activity FADS1/2 affected by susceptibility alleles, we generated mutant mice heterozygously lacking both Fads1 / 2 genes. We measured...

Among antipsychotics, clozapine is associated with a high risk of seizures. This study aimed to generate novel hypotheses regarding trends in the onset clozapine-induced seizures using JADER (Japanese Adverse Drug Event Report) database. Seizures were defined according Standardized MedDRA Queries (SMQ) for convulsions (SMQ20000079). Trends assessed multivariate logistic regression analysis covariates sex, age, dose, antipsychotic polypharmacy, concomitant medications, and history convulsive...

<title>Abstract</title> Background Gene-environment interactions may enhance our understanding of hypertension. Our previous study highlighted the importance considering psychosocial factors in gene discovery for blood pressure (BP) but was limited statistical power and population diversity. To address these challenges, we conducted a multi-population genome-wide association (GWAS) BP accounting gene-depressive symptomatology (DEPR) larger more diverse sample. Results included 564,680 adults...

Suicidal ideation (SI) and behavior (SB) are major public health concerns, but risk factors for their development progression poorly understood. We used ICD codes a natural language processing algorithm to identify individuals in hospital biobank with SI-only, SB, controls without either. compared the profiles of SB SI-only patients controls, each other, using phenome-wide association studies (PheWAS) polygenic scores (PRS). PheWAS identified many plus specific psychiatric disorders which...

Recent genome-wide association studies (GWASs) of schizophrenia (SCZ) identified several susceptibility genes and suggested shared genetic components between SCZ bipolar disorder (BD). We conducted a study single nucleotide polymorphisms (SNPs) selected according to previous GWAS targeting psychotic disorders (SCZ BD) in the Japanese population. Fifty-one SNPs were analyzed two-stage design using first-set screening samples (all SNPs: 1,032 SCZ, 1,012 BD, 993 controls) second-set replication...
