Across TCGA pan-cancer cohorts, RNASEH1P2 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RNASEH1P2’s most consistent transcriptional readouts.
The strongest signal is observed in bladder urothelial carcinoma (BLCA), where RNASEH1P2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RNASEH1P2 is over-expressed in tumor, although a few such as ESCA show the opposite, repressed pattern.
BLCA, COAD, and HNSC are the cancer types where RNASEH1P2 tumor–normal differential expression is most reproducible.
