Across TCGA pan-cancer cohorts, FAM197Y9 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of FAM197Y9’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where FAM197Y9 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types FAM197Y9 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
BRCA, HNSC, and THCA are the cancer types where FAM197Y9 tumor–normal differential expression is most reproducible.
