Subpopulations and group heritage

SNP500Cancer studies the genomes of 102 individuals of self-described heritage. All samples are anonymized. These individuals are not a random sample and as such the generalizability of the data provided here is not certain, particularly for the study of population genetics. However, where literature data are sparse, the allele frequencies in the SNP500Cancer set of 102 should provide assistance in determining how informative a given SNP is overall, as well as in each of the four subgroups. It should also be noted that the subgroups consist of subjects culled from different geographic and ethnic populations. This approach was chosen for the purposes of discovery and validation of SNPs of interest to molecular epidemiology studies in cancer.

SNP500Cancer subjects are from the following populations:
