PNPLA2

Mutation & survival
SurvivalMutationKaplan–Meier · TCGA cohorts

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.

Mutation survival associations by lineage

Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
