Across TCGA pan-cancer cohorts, PNMT mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated PNMT data layer compared with 21 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in lung adenocarcinoma (LUAD), where higher PNMT mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated PNMT expression acts as an unfavorable survival marker.
LUAD are the cancer types where PNMT mass-spec protein most reproducibly stratifies survival.
