Is there a karyotype for ADHD?

Currently, there is no specific karyotype associated with Attention Deficit Hyperactivity Disorder (ADHD). ADHD is a complex neurodevelopmental disorder influenced by a combination of genetic, environmental, and neurobiological factors. While some studies have suggested potential genetic links, ADHD does not have a distinct chromosomal abnormality that can be identified through karyotyping. Research continues to explore the genetic underpinnings of ADHD, but a clear karyotypic marker remains elusive.
