Across TCGA pan-cancer cohorts, TTBK1 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated TTBK1 data layer compared with 23 for mass-spec protein and 11 for mutation status.
The strongest signal is observed in glioblastoma multiforme (GBM), where higher TTBK1 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated TTBK1 expression acts as an unfavorable survival marker, although some lineages such as GBM and CCRCC show a favorable association.
GBM and CCRCC are the cancer types where TTBK1 mass-spec protein most reproducibly stratifies survival.
