Across TCGA pan-cancer cohorts, C12orf40 RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of C12orf40’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where C12orf40 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types C12orf40 is over-expressed in tumor, although a few such as BRCA show the opposite, repressed pattern.
KIRC, BRCA, and CHOL are the cancer types where C12orf40 tumor–normal differential expression is most reproducible.
