Across TCGA pan-cancer cohorts, OR12D2 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of OR12D2’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where OR12D2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR12D2 is over-expressed in tumor.
KIRC, CHOL, and LUAD are the cancer types where OR12D2 tumor–normal differential expression is most reproducible.
