Across TCGA pan-cancer cohorts, C17orf80 mass-spec protein differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of C17orf80’s most consistent transcriptional readouts.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where C17orf80 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types C17orf80 is over-expressed in tumor, although a few such as PDAC show the opposite, repressed pattern.
PDAC and LSCC are the cancer types where C17orf80 tumor–normal differential expression is most reproducible.
