VNTR polymorphism influences reactivity to smoking cues," Journal of Abnormal Psychology, vol.
The genotyping of DRD4
exon III was carried out by polymerase chain reaction with the following primer sequences:

is one of several genes that determines the way dopamine -- a crucial neurotransmitter, or chemical messenger -- is released in the brain.
The effect of the OPRM1 and DRD4
polymorphisms on the relation between attentional bias and alcohol use in adolescence and young adulthood.
The genes are the dopamine transporter 1 (DAT1) gene, the three D2-like dopamine receptor (DRD2, DRD3, and DRD4
) genes and the monoamine oxidase-A gene.

Heritability of children's prosocial behavior and differential susceptibility to parenting by variation in the Dopamine D4 Receptor (DRD4
 Zhao and colleagues did not find an association between DRD4
and ADHD, but did find that DRD4
was associated with the internalizing behaviors of ADHD.
Returning to her lab, she focussed on a tiny section of DRD4
genes and found that skiers and riders with a particular variant of DNA were much more likely to score high on the tests of risk-taking.
