Across TCGA pan-cancer cohorts, IFITM3P2 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of IFITM3P2’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where IFITM3P2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types IFITM3P2 is over-expressed in tumor, although a few such as LUAD show the opposite, repressed pattern.
HNSC, ESCA, and LUAD are the cancer types where IFITM3P2 tumor–normal differential expression is most reproducible.
