Across TCGA pan-cancer cohorts, C7orf77 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of C7orf77’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where C7orf77 RNA is repressed in tumor relative to normal tissue. In most cancer types C7orf77 is over-expressed in tumor, although a few such as LUSC and LUAD show the opposite, repressed pattern.
LUSC, LUAD, and BRCA are the cancer types where C7orf77 tumor–normal differential expression is most reproducible.
