OBJECTIVE The brain reward circuits that promote drug abuse may also be involved in pleasure seeking behavior and food cravings observed in severely obese subjects. Drug addiction polymorphisms such as the TaqI A1 allele of the dopamine D2 receptor (DRD2) are associated with cocaine, alcohol, and opioid use, but few studies have linked DRD2 to food craving. Other genes such as the leptin receptor gene (LEPR) and mu-opioid receptor gene (OPRM1) that affect appetite and pleasure centers in the… CONTINUE READING
