• Analysis of differentially methylated regions in great apes and extinct hominids provides support for the evolutionary hypothesis of schizophrenia 

      Banerjee, Niladri; Polushina, Tatiana; Bettella, Francesco; Steen, Vidar Martin; Andreassen, Ole Andreas; Le Hellard, Stephanie (Peer reviewed; Journal article, 2018-12-11)
      Introduction: The persistence of schizophrenia in human populations separated by geography and time led to the evolutionary hypothesis that proposes schizophrenia as a by-product of the higher cognitive abilities of modern ...
    • Elevated expression of a minor isoform of ANK3 is a risk factor for bipolar disorder 

      Hughes, Timothy; Sønderby, Ida Elken; Polushina, Tatiana; Hansson, Lars Johan Axel; Holmgren, Asbjørn; Athanasiu, Lavinia; Melbø-Jørgensen, Christian; Hassani, Sahar; Hoeffding, Louise K.; Herms, Stefan; Bergen, Sarah E.; Karlsson, Robert; Song, Jie; Rietschel, Marcella; Nöthen, Markus M.; Forstner, Andreas J.; Hoffmann, Per; Hultman, Christina M.; Landén, Mikael; Cichon, Sven; Werge, Thomas; Andreassen, Ole Andreas; Le Hellard, Stephanie; Djurovic, Srdjan (Peer reviewed; Journal article, 2018)
      Ankyrin-3 (ANK3) is one of the few genes that have been consistently identified as associated with bipolar disorder by multiple genome-wide association studies. However, the exact molecular basis of the association remains ...
    • Genetic variation in 117 myelination-related genes in schizophrenia: Replication of association to lipid biosynthesis genes 

      Stokowy, Tomasz; Polushina, Tatiana; Sønderby, Ida Elken; Karlsson, Robert; Giddaluru, Sudheer; Le Hellard, Stephanie; Bergen, Sarah E; Sullivan, Patrick F; Andreassen, Ole Andreas; Djurovic, Srdjan; Hultman, Christina M.; Steen, Vidar Martin (Peer reviewed; Journal article, 2018-05-02)
      Schizophrenia is a serious psychotic disorder with high heritability. Several common genetic variants, rare copy number variants and ultra-rare gene-disrupting mutations have been linked to disease susceptibility, but there ...
    • Recently evolved human-specific methylated regions are enriched in schizophrenia signals 

      Banerjee, Niladri; Polushina, Tatiana; Bettella, Francesco; Giddaluru, Sudheer; Steen, Vidar Martin; Andreassen, Ole Andreas; Le Hellard, Stephanie (Peer reviewed; Journal article, 2018)
      Background: One explanation for the persistence of schizophrenia despite the reduced fertility of patients is that it is a by-product of recent human evolution. This hypothesis is supported by evidence suggesting that ...
