Across TCGA pan-cancer cohorts, PIGL RNA differs between tumor and matched normal tissue in 13 of 18 cancer types tested, making tumor–normal expression one of PIGL’s most consistent transcriptional readouts.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where PIGL RNA is more highly expressed in tumor relative to normal tissue. In most cancer types PIGL is over-expressed in tumor, although a few such as KICH and BRCA show the opposite, repressed pattern.
HNSC, COAD, and KICH are the cancer types where PIGL 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 PIGL RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
