Across TCGA pan-cancer cohorts, PNPLA2 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated PNPLA2 data layer compared with 27 for mass-spec protein and 6 for mass-spec protein.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where higher PNPLA2 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PNPLA2 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
LIHC and UCEC are the cancer types where PNPLA2 Mutation most reproducibly stratifies survival.
