KRT4

Across TCGA pan-cancer cohorts, KRT4 Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated KRT4 data layer compared with 23 for mass-spec protein and 4 for mass-spec protein.

The strongest signal is observed in sarcoma (SARC), where higher KRT4 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated KRT4 expression acts as an unfavorable survival marker, although some lineages such as SKCM show a favorable association.

SARC, SKCM, and HNSC are the cancer types where KRT4 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.
