Across TCGA pan-cancer cohorts, OR7E66P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of OR7E66P’s most consistent transcriptional readouts.
The strongest signal is observed in esophageal carcinoma (ESCA), where OR7E66P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR7E66P is over-expressed in tumor.
ESCA and STAD are the cancer types where OR7E66P tumor–normal differential expression is most reproducible.
