Background: Attention-deficit/hyperactivity disorder (ADHD) is a common, highly heritable neurodevelopmental disorder with profound cognitive, behavioral, and psychosocial impairments with persistence across the life cycle. Our initial genome-wide screening approach for copy number variants (CNVs) in ADHD implicated a duplication of…

M.; Fliers, Ellen A.; Franke, Barbara; Minderaa, Ruud B.; Ormel, Johan; Sergeant, Joseph A.; Verhulst, Frank C.; Buitelaar, Jan K.; Hoekstra, Pieter J. – Journal of Child Psychology and Psychiatry, 2010
Background: Symptoms of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) often co-occur. Given the previously found familiality of ASD symptoms in children with ADHD, addressing these symptoms may be useful for genetic association studies, especially for candidate gene findings that have not been consistently…

van der Meulen, Emma M.; Bakker, Steven C.; Pauls, David L.; Oteman, Nicole; Kruitwagen, Cas L. J. J.; Pearson, Peter L.; Sinke, Richard J.; Buitelaar, Jan K. – Journal of Child Psychology and Psychiatry, 2005
Background: A minority of patients with attention-deficit hyperactivity disorder (ADHD) do not respond favorably to methylphenidate. This has been partially associated with homozygosity for the Dopamine transporter (DAT1) 10-repeat allele and the presence of one or two Dopamine D4 receptor (DRD4) 7-repeat alleles. This study examined the sibling…
