Genotyping was performed using an Illumina 500GX BeadStation. This genotyping platform uses highly multiplexed (1536 site Arrays) ligation assays with multiple levels of specificity to obtain optimal results. For the large-scale genotyping, we have select
erformed using the LD_Select from the method of Carlson (2004; AJHG). Binning criteria for tagSNP selection were MAF cutoff of 5% and rē threshold of 0.65. All SNPs above the MAF threshold will either be directly genotyped or will exceed the specified lev
