Across TCGA pan-cancer cohorts, PENK Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PENK data layer compared with 25 for mass-spec protein and 2 for mass-spec protein.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where higher PENK Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated PENK expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
LIHC, PRAD, and LUAD are the cancer types where PENK Mutation most reproducibly stratifies survival.
