Across TCGA pan-cancer cohorts, RPL21P30 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RPL21P30’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where RPL21P30 RNA is repressed in tumor relative to normal tissue. In most cancer types RPL21P30 is over-expressed in tumor, although a few such as KICH and UCEC show the opposite, repressed pattern.
KICH, PAAD, and UCEC are the cancer types where RPL21P30 tumor–normal differential expression is most reproducible.
