Across TCGA pan-cancer cohorts, OR7E21P RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of OR7E21P’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where OR7E21P RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR7E21P is over-expressed in tumor.
LUAD and LUSC are the cancer types where OR7E21P tumor–normal differential expression is most reproducible.
