Text

Participants were genotyped at 12 SNPs in the DRD2, which were part of the Addiction Array (Hodgkinson et al., 2008), based on the Illumina Golden-Gate platform. Arrays were imaged with an Illumina Bead-station GX500, and the data were analyzed with GenCall v6.2.0.4 and GTS Reports software v5.1.2.0 (Illumina). Criteria for sample exclusion and determining genotyping failure were previously described (Hodgkinson et al., 2008).
