Figure 5. Heatmap of transcription across gene deserts. The relative expression of each of the 63 gene deserts with at least 1,000 RNA-seq read counts (from a single library) is shown for each of the 42 human RNA-seq data sets surveyed. Read intensity is scaled in log₁₀ from 0 (blue) to greater than 5 (red). The IBM2 16 tissue mix total RNA DSN (16-tDSN) library reveals high levels of transcription across the vast majority of gene deserts.
