Across TCGA pan-cancer cohorts, MRPS21P8 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of MRPS21P8’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where MRPS21P8 RNA is repressed in tumor relative to normal tissue. In most cancer types MRPS21P8 is over-expressed in tumor, although a few such as ESCA and LUAD show the opposite, repressed pattern.
ESCA and LUAD are the cancer types where MRPS21P8 tumor–normal differential expression is most reproducible.
