As another example, the pseudogene PTENP1 affected the post-transcriptional regulation of its parental gene (PTEN) through competition for PTEN-targeting miRNAs, and patients who did express PTENP1 showed a more favorable outcome compared to those who did not express PTENP1 in clear cell renal cell carcinoma [16]. Here, PTEN is linked to clear cell renal carcinoma.
