For this cross-population mapping study, the analysis focused on 10 genotyped SNPs: rs16969968 and its genotyped correlates, defined by the r2 ≥ 0.8 bin (that is, the set of SNPs satisfying r2 ≥ 0.8) for rs16969968 in the HapMap CEU (Centre d'Etudie Polymorphisme Humaine (CEPH), Utah residents with ancestry from northern and western Europe) sample. These SNPs were part of a larger set genotyped in the FSCD sample by the Center for Inherited Disease Research (CIDR) with a custom Illumina SNP array to cover multiple candidate genes. Details of the CIDR genotyping procedures are available at their website .
