Across TCGA pan-cancer cohorts, CCK Mutation is linked to patient survival in 1 of 34 cancer types, making it a survival-associated CCK data layer compared with 24 for mass-spec protein and 3 for mass-spec protein.

The strongest signal is observed in skin cutaneous melanoma (SKCM), where higher CCK Mutation is associated with better overall survival. In most high-consensus cancer types, elevated CCK expression acts as an unfavorable survival marker, although some lineages such as SKCM show a favorable association.

SKCM are the cancer types where CCK 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.
