Across TCGA pan-cancer cohorts, RFPL4AP1 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of RFPL4AP1’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where RFPL4AP1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RFPL4AP1 is over-expressed in tumor.
HNSC and LUSC are the cancer types where RFPL4AP1 tumor–normal differential expression is most reproducible.
