Influence of dopaminergic gene functional polymorphisms on OT-E process skills performance.

<p>Bar graphs show the results of the OT-E Process Skills performance in study participants expressing different dopamine-related gene polymorphisms. No differences were found among carriers of different <i>DRD1</i> (<b>A</b>), <i>DRD2</i> (<b>B</b>), <i>DRD4</i> (<b>D</b>)<b>, </b><i>DRD5</i> (<b>E</b>)<b>,</b> and <i>DAT1</i> (<b>G</b>) polymorphisms in the trained group. Compared to individuals carrying the <i>DRD3 A1/A1(Ser/Ser)</i> genotype, <i>DRD3 A1/A2(Ser/Gly)</i> carriers showed an increased response to CT (<b>C</b>). <i>COMT L/L-H/L (Val/Val-Val/Met)</i> carriers also benefitted the most from CT (<b>F</b>). Table (<b>H</b>) shows sample size.
