All SNPs with an r2 value >0.5 with each index SNP in the 1KGP AFR populations in a 1Mb window around each index variant were catalogued. We used the UCSC Genome Browser (http://genome.ucsc.edu/) to illustrate the correlated SNPs which overlap chromatin features from these tissues as well as chromatin features from seven cell lines utilized in the ENCODE Project (Supplementary Figures 5a–c). All of the results from these analyses are provided in Supplementary Tables 16–19.
