Across TCGA pan-cancer cohorts, OR7E129P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of OR7E129P’s most consistent transcriptional readouts.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where OR7E129P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR7E129P is over-expressed in tumor.
LUSC and STAD are the cancer types where OR7E129P tumor–normal differential expression is most reproducible.
