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

Figure 2

The fractions of transcripts from the whole-genome dataset that do not contain SNPs in their 100 bp long upstream regions as a function of region location. -axis shows the borders of 100 bp bins relative to the TSS. -axis means the fraction of transcripts that lack SNPs in the respective 100 bp bin.
