Across TCGA pan-cancer cohorts, RFPL4AL1 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of RFPL4AL1’s most consistent transcriptional readouts.
The strongest signal is observed in colon adenocarcinoma (COAD), where RFPL4AL1 RNA is repressed in tumor relative to normal tissue. In most cancer types RFPL4AL1 is over-expressed in tumor, although a few such as COAD and KICH show the opposite, repressed pattern.
COAD, KICH, and READ are the cancer types where RFPL4AL1 tumor–normal differential expression is most reproducible.
