A set of 64 ancestry informative markers was genotyped as part of a 96 SNP Biorepository Panel by the Rutgers University Cell and DNA Repository. These markers were used in SNPrelate, a function in R, to assign ancestry groups. HapMap populations were included as reference groups. There was high concordance (98%) between self-reported and genetically determined ancestry among European Americans. Only individuals with a genetic ancestry of European American were included in the analysis because the metric was optimized for this population (Bloom et al., 2011).
