Across TCGA pan-cancer cohorts, PGBD4P2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of PGBD4P2’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where PGBD4P2 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types PGBD4P2 is over-expressed in tumor, although a few such as THCA show the opposite, repressed pattern.
BRCA and THCA are the cancer types where PGBD4P2 tumor–normal differential expression is most reproducible.
