Across TCGA pan-cancer cohorts, OR14K1 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of OR14K1’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where OR14K1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types OR14K1 is over-expressed in tumor, although a few such as THCA and COAD show the opposite, repressed pattern.
BRCA, THCA, and PRAD are the cancer types where OR14K1 tumor–normal differential expression is most reproducible.
