Across TCGA pan-cancer cohorts, RAP1BP1 RNA differs between tumor and matched normal tissue in 5 of 18 cancer types tested, making tumor–normal expression one of RAP1BP1’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where RAP1BP1 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types RAP1BP1 is over-expressed in tumor, although a few such as UCEC and READ show the opposite, repressed pattern.
KICH, LUAD, and HNSC are the cancer types where RAP1BP1 tumor–normal differential expression is most reproducible.
