In fact, Welch and collaborators found that 309 pseudogenes exhibit significant differential expression among BC subtypes, and their expression pattern allows recognizing tumor samples from normal samples and discriminating the basal subtype from the luminal and Her2 subtypes; of them, 177 transcribed pseudogenes possess binding sites for co-expressed miRs that are also predicted to target their parent genes [199]. Here, ERBB2 is linked to neoplasm.
