Human Genes Encoding Transcription Factors and Chromatin-Modifying Proteins Have Low Levels of Promoter Polymorphism: A Study of 1000 Genomes Project Data

Figure 1

Cumulative percentage plot for the fraction of human transcripts from the whole-genome dataset, possessing certain numbers of SNPs in their 500 bp long regions upstream annotated transcription start sites. -axis denotes the threshold SNP content in 500 bp upstream TSS. -axis denotes the cumulative fraction of the whole-genome dataset of transcripts.
