POLB

Across TCGA pan-cancer cohorts, POLB Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated POLB data layer compared with 23 for mass-spec protein and 5 for mass-spec protein.

The strongest signal is observed in kidney renal papillary cell carcinoma (KIRP), where higher POLB Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated POLB expression acts as an unfavorable survival marker.

KIRP, UCEC, and LUAD are the cancer types where POLB 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.
