Interaction between serotonin transporter promoter and dopamine receptor D4 polymorphisms on decision making.

Progress in neuro-psychopharmacology & biological psychiatry - 1 Oct 2009

Ha Ra Yeon, Namkoong Kee, Kang Jee In, Kim Yang Tae, Kim Se Joo

Abstract excerpt

Appropriate decision making is an important brain function to maintain our lives. The Iowa gambling task (IGT) is a tool for decision making under ambiguity. The aims of this study were to evaluate the influence of serotonin transporter linked polymorphic region (5-HTTLPR) and dopamine receptor D4 (DRD4) polymorphisms and their interaction on IGT performance. One hundred fifty-nine normal subjects were involved...
