Across TCGA pan-cancer cohorts, GTF3AP2 RNA differs between tumor and matched normal tissue in 2 of 18 cancer types tested, making tumor–normal expression one of GTF3AP2’s most consistent transcriptional readouts.
The strongest signal is observed in breast invasive carcinoma (BRCA), where GTF3AP2 RNA is repressed in tumor relative to normal tissue. In most cancer types GTF3AP2 is over-expressed in tumor, although a few such as BRCA and THCA show the opposite, repressed pattern.
BRCA and THCA are the cancer types where GTF3AP2 tumor–normal differential expression is most reproducible.
