Across TCGA pan-cancer cohorts, HNMT RNA differs between tumor and matched normal tissue in 11 of 18 cancer types tested, making tumor–normal expression one of HNMT’s most consistent transcriptional readouts.
The strongest signal is observed in kidney chromophobe (KICH), where HNMT RNA is repressed in tumor relative to normal tissue. In most cancer types HNMT is over-expressed in tumor, although a few such as KICH and KIRP show the opposite, repressed pattern.
KICH, KIRP, and UCEC are the cancer types where HNMT 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 HNMT RNA (log2); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
