Figure 1.

Venn Diagrams displaying the relative number of genome-wide SNPs in several classes. SNP markers are from Ensembl. A) Comparison of SNPs in the gene-centered annotations of promoter, coding, or splice control regions. B) Comparison between coding SNPs and evolutionarily constrained SNPs. C) Comparison between constrained elements and regulatory features. D) Comparison between constrained elements and genic regions.
