et al. 2009), we genotyped 3,827 (2,817 EA and 1,010 AA) control samples with the Affymetrix 6.0 array, selected for eligibility based on previous laboratory study of genotypic ancestral background and DNA quality. Of these, over 95% (3,667) of the control samples passed stringent sample and genotypic QC and were suitable for our analysis, on the basis of having both phenotypic and genotypic data. Genotypes and phenotypic data for these controls are available by application to dbGaP (Database of Genotypes and Phenotypes, dbgap.ncbi.nlm.nih.gov, Study Accessions: phs000021.v2.p1 and phs000167.v1.p1), and DNA, LCLs, and additional phenotypic data are available through the NIMH repository (nimhgenetics.org).
