BACKGROUND: There is clinical interest in recognising copy number variants (CNVs) in children as many have immediate and long-term health implications. Neurodevelopmental CNVs are associated with intellectual disability, autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), conditions typically diagnosed by medical practitioners. However, neurodevelopmental CNVs may have additional, early developmental impacts that have yet to be examined in unselected populations.
