Across TCGA pan-cancer cohorts, MRPS21P7 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of MRPS21P7’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where MRPS21P7 RNA is repressed in tumor relative to normal tissue. In most cancer types MRPS21P7 is over-expressed in tumor, although a few such as KIRC and KICH show the opposite, repressed pattern.
KIRC and KICH are the cancer types where MRPS21P7 tumor–normal differential expression is most reproducible.
