Across TCGA pan-cancer cohorts, KCNK4 mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated KCNK4 data layer compared with 19 for mass-spec protein and 5 for mutation status.

The strongest signal is observed in glioblastoma multiforme (GBM), where higher KCNK4 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated KCNK4 expression acts as an unfavorable survival marker.

GBM are the cancer types where KCNK4 mass-spec protein most reproducibly stratifies survival.

mass-spec protein 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.
