Across TCGA pan-cancer cohorts, PRAMEF2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of PRAMEF2’s most consistent transcriptional readouts.
The strongest signal is observed in lung adenocarcinoma (LUAD), where PRAMEF2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types PRAMEF2 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
LUAD and THCA are the cancer types where PRAMEF2 tumor–normal differential expression is most reproducible.
