What chromosomes does attention deficit disorder affect?

Attention deficit hyperactivity disorder (ADHD), commonly referred to as attention deficit disorder (ADD), is a complex neurodevelopmental condition influenced by genetic factors, but it is not directly linked to specific chromosomes. Research has shown that several genes associated with dopamine regulation, which may be located on various chromosomes, can contribute to ADHD. However, the exact genetic basis is multifactorial and involves interactions between multiple genes and environmental factors rather than a direct effect on specific chromosomes.
