PPP1R18

Across TCGA pan-cancer cohorts, PPP1R18 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated PPP1R18 data layer compared with 24 for mass-spec protein and 4 for mass-spec protein.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PPP1R18 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PPP1R18 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.

HNSC, UCEC, and SARC are the cancer types where PPP1R18 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.
