Figure 2 includes genome browser plots showing association P-values and relevant genomic information for three regions: 18q22.1 which produced the lowest GenRED P-value (all subjects); SP4/7p15.3, the best finding that received increased support in the meta-analysis; and 1p13.3, which was not supported in the meta-analysis, but contained the largest number of SNPs with the lowest P-values in two large LD blocks in the GenRED analysis, and which spans a set of interesting candidate genes. Genotyping cluster plots for top SNPs with P<10−6 (Table 2) or tags for those SNPs are provided in online file SNP_intensity_cluster_plots.pdf.
