Molecular genetic findings on ADHD have mainly arisen from functional candidate gene association studies and a number of pooled and meta-analyses have now been conducted. There is consistent evidence of association between ADHD and a dopamine D4 receptor gene VNTR and a dopamine D5 receptor gene microsatellite marker.
What chromosome is ADHD located on?

Can DNA tell if you have ADHD?
Genetic science hasn't reached the point where it can reliably test for the presence of ADHD. Neurological conditions are much more difficult to detect genetically, and the role of that a person's environment plays in the disorder, and its severity, aren't fully understood at this point.May 10, 2021
Does 23andMe test for mental disorders?
Companies like 23andme and Navigenics provide genetic DNA testing reports that purportedly tell you your risk factors for getting not only certain medical conditions, but also mental disorders, like bipolar or attention deficit disorder.Jul 24, 2010
