Across TCGA pan-cancer cohorts, DUX4L46 RNA differs between tumor and matched normal tissue in 3 of 18 cancer types tested, making tumor–normal expression one of DUX4L46’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where DUX4L46 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types DUX4L46 is over-expressed in tumor, although a few such as ESCA show the opposite, repressed pattern.
KIRC, KIRP, and ESCA are the cancer types where DUX4L46 tumor–normal differential expression is most reproducible.
