PPIG

Across TCGA pan-cancer cohorts, PPIG Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated PPIG data layer compared with 25 for mass-spec protein and 5 for mass-spec protein.

The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher PPIG Mutation is associated with better disease-free survival. In most high-consensus cancer types, elevated PPIG expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.

UCEC, GBM, and SCLC are the cancer types where PPIG 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.
