摘要: Pathological gambling (PG) has become a growing public health problem in many countries around the world. PG is an impulse control disorder and its behavior psychopathology present similarities with substance abuse disorders. Evidence from twin studies supports significant genetic predisposition to PG, but precise loci still remain unclear. The study investigates allele genotype distribution of polymorphisms serotonin transporter, receptor 1B 2A genes 140 sib-pairs discordant for diagnosis PG. A association C/C T102C (rs 6313) polymorphism phenotype was observed [OR = 1.7 (1.1–3.4)]. This preliminary result consistent hypothesis that system associated addiction similar results have been reported nicotine alcohol dependence.
