Across TCGA pan-cancer cohorts, OR2A5 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of OR2A5’s most consistent transcriptional readouts.

The strongest signal is observed in thyroid carcinoma (THCA), where OR2A5 RNA is repressed in tumor relative to normal tissue. In most cancer types OR2A5 is over-expressed in tumor, although a few such as THCA and KIRC show the opposite, repressed pattern.

THCA and KIRC are the cancer types where OR2A5 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 OR2A5 RNA (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
