Across TCGA pan-cancer cohorts, PRAMEF18 RNA differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of PRAMEF18’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where PRAMEF18 RNA is repressed in tumor relative to normal tissue. In most cancer types PRAMEF18 is over-expressed in tumor, although a few such as BRCA show the opposite, repressed pattern.
BRCA are the cancer types where PRAMEF18 tumor–normal differential expression is most reproducible.
