Across TCGA pan-cancer cohorts, C7orf26 mass-spec protein differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of C7orf26’s most consistent transcriptional readouts.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where C7orf26 mass-spec protein is more highly expressed in tumor relative to normal tissue. In most cancer types C7orf26 is over-expressed in tumor, although a few such as LUAD and COAD show the opposite, repressed pattern.
CCRCC, HNSC, and LUAD are the cancer types where C7orf26 tumor–normal differential expression is most reproducible.
