The Association of DRD2 −141C and ANKK1 TaqIA Polymorphisms with Alcohol Dependence in Korean Population Classified by the Lesch Typology

Dopamine receptors are associated with reward and dependence towards alcohol. The polymorphisms of dopamine D2 receptor (DRD2) genes have been reported to be involved in susceptibility to alcoholism. Therefore, we investigated the association of three single-nucleotide polymorphisms (SNPs) in DRD2 and ankyrin repeat and kinase domain containing one (ANKK1
