Pseudogene occurrence in the TCGA breast cancer samples and overlap with ENCODE functional genomics annotations. (A) Cumulative distribution function showing how many samples pseudogenes occur in. Approximately 65% of the 2,012 transcribed pseudogenes occur in fewer than 20 samples. Roughly 25% of the pseudogenes occur in at least 80 samples. (B) Bar chart comparing the set of 287 pseudogenes transcribed in breast cancer with the full psiDR v. 0 annotation set. The asterisks indicate categories that are significantly enriched in the set of 287 pseudogenes compared to the full set (p < 0.002, χ² test).
