Across TCGA pan-cancer cohorts, OR13C3 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of OR13C3’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where OR13C3 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR13C3 is over-expressed in tumor.

HNSC and LUAD are the cancer types where OR13C3 tumor–normal differential expression is most reproducible.

RNA tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in OR13C3 RNA (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
