McMahon YR 2016 UL http://biorxiv.org/content/early/2016/03/22/044412.abstract AB Bipolar disorder (BD) is a genetically complex mental illness characterized by severe oscillations of mood and behavior. Genome-wide association studies (GWAS) have identified several risk loci that together account for a small portion of the heritability. To identify additional risk loci, we performed a two-stage meta-analysis of >9 million genetic variants in 9,784 bipolar disorder patients and 30,471 controls, the largest GWAS of BD to date. In this study, to increase power we used ~2,000 lithium-treated cases with a long-term diagnosis of BD from the Consortium on Lithium Genetics, excess controls, and analytic methods optimized for markers on the X-chromosome. In addition to four known loci, results revealed genome-wide significant associations at two novel loci: an intergenic region on 9p21.3 (rs12553324, p = 5.87×10−9; odds ratio = 1.12) and markers within ERBB2 (rs2517959, p = 4.53×10−9; odds ratio = 1.13). No significant X-chromosome associations were detected and X-linked markers explained very little BD heritability. The results add to a growing list of common autosomal variants involved in BD and illustrate the power of comparing well-characterized cases to an excess of controls in GWAS.BDBipolar DisorderSCZSchizophreniaGWASGenome-wide Association StudySNPSingle Nucleotide PolymorphismMAFMinor Allele FrequencyOROdds RatioSDStandard DeviationCIConfidence IntervaleQTLexpression Quantitative Trait LocusGAIN-NIMHGenetic Association Information Network – National institute of Mental HealthWTCCCWellcome Trust Case Control ConsortiumSTEP-BDSystematic Treatment Enhancement Program for Bipolar DisorderTGENTranslational Genomics Research InstituteConLiGenThe International Consortium on Lithium GeneticsBoMABonn-MannheimdbGaPDatabase of Genotypes and PhenotypesNCPNon-Centrality Parameter
