Across TCGA pan-cancer cohorts, OR13I1P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of OR13I1P’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where OR13I1P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR13I1P is over-expressed in tumor, although a few such as LIHC show the opposite, repressed pattern.
KIRC and LIHC are the cancer types where OR13I1P tumor–normal differential expression is most reproducible.
