2 Figure 1 Manhattan Plot for Metabochip-Wide Analysis of BMI in African Americans The –log10 of p values for each SNP on the Metabochip is plotted against physical chromosomal positions. Green dots represent the SNPs in 21 BMI-related loci that were previously identified in European populations and fine-mapped on the Metabochip. Blue line: p = 2.5 × 10−7; red line: p = 5 × 10−8.

3 Figure 2 Regional-Association Plot for the New BMI-Related Locus at 2p23.2/BRE The –log10 of p values (left y axis) is plotted against the SNP genomic position based on NCBI build 37 (x axis); the estimated recombination rate from the 1000 Genomes Project for African populations is on the right y axis and is plotted in blue. The most significant SNP is denoted with a purple diamond. SNPs are colored to reflect correlation with the most significant SNP. Gene annotations are from the UCSC Genome Browser.
