Across TCGA pan-cancer cohorts, OR2AM1P RNA differs between tumor and matched normal tissue in 4 of 18 cancer types tested, making tumor–normal expression one of OR2AM1P’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where OR2AM1P RNA is repressed in tumor relative to normal tissue. In most cancer types OR2AM1P is over-expressed in tumor, although a few such as LUSC and BRCA show the opposite, repressed pattern.
LUSC, BRCA, and COAD are the cancer types where OR2AM1P tumor–normal differential expression is most reproducible.
