Single nucleotide polymorphisms (SNPs) for the same 726 HapMap version 3 individuals of CEU, CHB, GIH, JPT, LWK, MEX, MKK, and YRI, were selected (Release version 2) for use in the association analyses. Any SNP with MAF>5% in a population and with less than 20% missing data was included. This corresponds to between 1.1 million and 1.3 million SNPs per population.
