      Hegvik, Tor-Arne; Waløen, Kai; Pandey, Sunil Kumar; Faraone, Stephen V.; Haavik, Jan; Zayats, Tetyana (Peer reviewed; Journal article, 2019)
      Attention-Deficit/Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder with only symptomatic care available. Genome-wide association (GWA) studies can provide a starting point in the search for novel drug ...

    • Epistatic and gene wide effects in YWHA and aromatic amino hydroxylase genes across ADHD and other common neuropsychiatric disorders: Association with YWHAE 

      Jacobsen, Kaya Kvarme; Kleppe, Rune; Johansson, Stefan; Zayats, Tetyana; Haavik, Jan (Peer reviewed; Journal article, 2015-09)
      Monoamines critically modulate neurophysiological functions affected in several neuropsychiatric disorders. We therefore examined genes encoding key enzymes of catecholamine and serotonin biosynthesis (tyrosine and tryptophan ...

    • Expanding the toolbox of ADHD genetics. How can we make sense of parent of origin effects in ADHD and related behavioral phenotypes? 

      Zayats, Tetyana; Johansson, Stefan; Haavik, Jan (Peer reviewed; Journal article, 2015-10-16)
      Genome-wide association (GWA) studies have shown that many different genetic variants cumulatively contribute to the risk of psychiatric disorders. It has also been demonstrated that various parent-of-origin effects (POE) ...

    • Genetic association study of childhood aggression across raters, instruments, and age 

      Ip, Hill F.; van der Laan, Camiel M.; Krapohl, Eva M.

(Journal article; Peer reviewed, 2021)
      Childhood aggressive behavior (AGG) has a substantial heritability of around 50%. Here we present a genome-wide association meta-analysis (GWAMA) of childhood AGG, in which all phenotype measures across childhood ages from ...

    • Genome wide association study identifies variants in NBEA associated with migraine in bipolar disorder 

      Jacobsen, Kaya Kvarme; Nievergelt, Caroline M.; Zayats, Tetyana; Greenwood, Tifany A.; Anttila, Verneri; Akiskal, Hagop Souren; Haavik, Jan; Fasmer, Ole Bernt; Kelsoe, John R.; Johansson, Stefan; Ødegaard, Ketil Joachim (Peer reviewed; Journal article, 2015-10-12)
      Background. Migraine is a common comorbidity among individuals with bipolar disorder, but the underlying mechanisms for this co-occurrence are poorly understood. The aim of this study was to investigate the genetic background ...

    • Genome-wide analysis of attention deficit hyperactivity disorder in Norway 

      Zayats, Tetyana; Athanasiu, Lavinia; Sønderby, Ida Elken; Djurovic, Srdjan; Westlye, Lars Tjelta; Tamnes, Christian Krog; Fladby, Tormod; Aase, Heidi; Zeiner, Pål; Reichborn-Kjennerud, Ted; Knappskog, Per; Knudsen, Gun Peggy; Andreassen, Ole Andreas; Johansson, Stefan; Haavik, Jan (Peer reviewed; Journal article, 2015-04-13)
      Background Attention deficit hyperactivity disorder (ADHD) is a highly heritable neuropsychiatric condition, but it has been difficult to identify genes underlying this disorder. This study aimed to explore genetics of ...

    • Implication of the APP gene in intellectual abilities 

      Myrum, Craig; Nikolaienko, Oleksii; Bramham, Clive R.; Haavik, Jan; Zayats, Tetyana (Peer reviewed; Journal article, 2017)
      Background: Cognitive functions are highly heritable and polygenic, though the source of this genetic influence is unclear. On the neurobiological level, these functions rely on effective neuroplasticity, in which the ...
