Quantitative genetic studies (i.e., twin and adoption studies) suggest that genetic influences contribute substantially to the development of attention deficit hyperactivity disorder (ADHD. [] Key Result Significant associations were identified for several candidate genes including DAT1, DRD4, DRD5, 5HTT, HTR1B, and SNAP25.

The results of genetic studies investigating associations between putative susceptibility genes for ADHD and neuropsychological traits relevant for this disorder were reviewed, and the most investigated genes were DRD4, DAT1, COMT, MAOA, and DBH.

A state-of-the-art review of the molecular genetics of ADHD incorporating evidence from candidate gene and linkage designs, as well as genome-wide association studies of common single-nucleotide polymorphisms (SNPs) and rare copy number variations (CNVs).

Molecular Genetics of Attention Deficit–Hyperactivity Disorder (ADHD)

Converging lines of evidence and meta analyses of candidate gene studies have identified that polymorphisms within the dopamine receptor genes 4 and 5, the dopamine transporter gene (DAT1), the synaptosome-associated protein gene (SNAP25) and the serotonin receptor gene (5-HTT) are associated with an increased the risk of ADHD.

Converging neurobiological evidence suggests that ADHD involves alterations of catecholaminergic brain circuits, and evidence from family and twin studies shows that ADHD is a highly heritable disorder, and approximately 76% of the phenotypic variance can be explained by genetic factors.
