Across TCGA pan-cancer cohorts, OR9N1P RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of OR9N1P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where OR9N1P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR9N1P is over-expressed in tumor, although a few such as UCEC and THCA show the opposite, repressed pattern.
KIRC, UCEC, and THCA are the cancer types where OR9N1P tumor–normal differential expression is most reproducible.
