Across TCGA pan-cancer cohorts, GAPDHP40 RNA differs between tumor and matched normal tissue in 13 of 18 cancer types tested, making tumor–normal expression one of GAPDHP40’s most consistent transcriptional readouts.
The strongest signal is observed in kidney renal clear cell carcinoma (KIRC), where GAPDHP40 RNA is more highly expressed in tumor relative to normal tissue. In most cancer types GAPDHP40 is over-expressed in tumor.
KIRC, COAD, and LUSC are the cancer types where GAPDHP40 tumor–normal differential expression is most reproducible.
RNA tumor vs normal associations by lineage
Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in GAPDHP40 RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
