Abstract excerpt

INTRODUCTION: Background: food is a powerful reinforcer that motivates people to eat. The TaqI A1 polymorphism (rs1800497; T>C) downstream of the dopamine D2 receptor (DRD2) gene has been associated with diminished DRD2 receptor density, higher food reinforcement, and impaired eating behavior in adults. Objective: to evaluate the association between the rs1800497 polymorphism and the reinforcing value of food and...
