• DCLK1 Variants Are Associated across Schizophrenia and Attention Deficit/Hyperactivity Disorder 

      Håvik, Bjarte; Fernandes, Carla P. D.; Christoforou, Andrea; Ersland, Kari Merete; Giddaluru, Sudheer; Cichon, Sven; Steen, Vidar Martin; Hellard, Stéphanie Le; Johansson, Stefan; Bramham, Clive R.; Haavik, Jan (Peer reviewed; Journal article, 2012-04-23)
      Doublecortin and calmodulin like kinase 1 (DCLK1) is implicated in synaptic plasticity and neurodevelopment. Genetic variants in DCLK1 are associated with cognitive traits, specifically verbal memory and general cognition. ...
