Across TCGA pan-cancer cohorts, PPP1R3B Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated PPP1R3B data layer compared with 22 for mass-spec protein and 3 for mass-spec protein.
The strongest signal is observed in liver hepatocellular carcinoma (LIHC), where higher PPP1R3B Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PPP1R3B expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
LIHC, UCEC, and KICH are the cancer types where PPP1R3B Mutation most reproducibly stratifies survival.
