Across TCGA pan-cancer cohorts, NDUFS5P4 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of NDUFS5P4’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where NDUFS5P4 RNA is repressed in tumor relative to normal tissue. In most cancer types NDUFS5P4 is over-expressed in tumor, although a few such as BRCA and ESCA show the opposite, repressed pattern.
BRCA and ESCA are the cancer types where NDUFS5P4 tumor–normal differential expression is most reproducible.
