What is the gen associated with ADD?

Attention Deficit Disorder (ADD) is a complex condition influenced by multiple genetic factors rather than a single gene. Research has identified several genes associated with neurotransmitter systems, particularly those related to dopamine regulation, that may contribute to ADD. Variations in the dopamine transporter gene (DAT1) and the dopamine receptor genes (like DRD4) have been studied for their potential link to ADD symptoms. However, environmental factors also play a significant role in the development of the disorder.
