PPIF

Across TCGA pan-cancer cohorts, PPIF Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated PPIF data layer compared with 24 for mass-spec protein and 5 for mass-spec protein.

The strongest signal is observed in small cell lung cancer (SCLC), where higher PPIF Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PPIF expression acts as an unfavorable survival marker.

SCLC and COAD are the cancer types where PPIF 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.
