Across TCGA pan-cancer cohorts, FGF7P2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of FGF7P2’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where FGF7P2 RNA is repressed in tumor relative to normal tissue. In most cancer types FGF7P2 is over-expressed in tumor, although a few such as LUSC and THCA show the opposite, repressed pattern.
LUSC and THCA are the cancer types where FGF7P2 tumor–normal differential expression is most reproducible.
