KCNA5

Across TCGA pan-cancer cohorts, KCNA5 mass-spec protein differs between tumor and matched normal tissue in 1 of 18 cancer types tested, making tumor–normal expression one of KCNA5’s most consistent transcriptional readouts.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where KCNA5 mass-spec protein is repressed in tumor relative to normal tissue. In most cancer types KCNA5 is over-expressed in tumor, although a few such as HNSC show the opposite, repressed pattern.

HNSC are the cancer types where KCNA5 tumor–normal differential expression is most reproducible.

mass-spec protein tumor vs normal associations by lineage

Ranked by sampling consensus. Fold-change is the tumor-versus-normal difference in KCNA5 mass-spec protein (log₂); positive values indicate higher expression in tumor. p-values are from the differential-expression test.
