British scientists announced that attention-deficit/hyperactivity disorder (ADHD) has been linked to deleted or duplicated DNA segments (copy number variants), which leads to developmental difference in the brains of children with the condition.
Researchers scanned genomes of 366 children with ADHD and compared them with 1,047 unrelated, ethnically matched control subjects. They reported full results in The Lancet.
Rare copy number variants were almost twice as common in children with ADHD compared to the other children. Researchers commented to Reuters that there was a significant overlap between copy number variants found in ADHD and elements of the genome linked to autism and schizophrenia, specifically in a region on chromosome 16.
