Heterogeneity analysis provides evidence for a genetically homogeneous subtype of bipolar-disorder. by Caroline C McGrouther, Aaditya V Rangan, Arianna Di Florio, Jeremy A Elman, Nicholas J Schork, John Kelsoe, Bipolar Disorder Working Group of the Psychiatric Genomics Consortium

“…We first apply this covariate-corrected biclustering algorithm to a cohort of 2524 BD cases and 4106 controls from the Bipolar Disease Research Network (BDRN) within the Psychiatric Genomics Consortium (PGC). We find evidence of genetic heterogeneity delineating a statistically significant bicluster comprising a subset of BD cases which exhibits a disease-specific pattern of differential-expression across a subset of SNPs. …”

The left amygdala is genetically sexually-dimorphic: multi-omics analysis of structural MRI volumes by Yuanyuan Gui, Geyu Zhou, Shuya Cui, Hongyu Li, Hui Lu, Hongyu Zhao

“…We also constructed polygenic risk scores (PRS) to investigate sex-specific genetic correlations between left amygdala volume and mental disorders (N = 25,576~105,318) of Psychiatric Genomics Consortium and other traits of UKB (N = 347,996). …”

Investigating the causal effects of childhood and adulthood adiposity on later life mental health outcome: a Mendelian randomization study by Sweta Pathak, Tom G. Richardson, Eleanor Sanderson, Bjørn Olav Åsvold, Laxmi Bhatta, Ben M. Brumpton

“…We used summary statistics from a genome-wide association study (GWAS) of UK Biobank (n = 453,169) and large-scale consortia of anxiety (Million Veteran Program) and depression (Psychiatric Genomics Consortium) (n = 175,163 and n = 173,005, respectively). …”

Causal associations between iron levels in subcortical brain regions and psychiatric disorders: a Mendelian randomization study by Wei Du, Biqiu Tang, Senhao Liu, Wenjing Zhang, Su Lui

“…The genetic instrumental variables linked to iron levels and psychiatric disorders were derived from the genome-wide association studies data of the UK Biobank Brain Imaging and Psychiatric Genomics Consortium. Bidirectional causal estimation was primarily obtained using the inverse variance weighting (IVW) method. …”
