Across TCGA pan-cancer cohorts, HIPK2 mass-spec protein is linked to patient survival in 2 of 34 cancer types, making it a survival-associated HIPK2 data layer compared with 26 for mass-spec protein and 8 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher HIPK2 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated HIPK2 expression acts as an unfavorable survival marker, although some lineages such as PDAC and LSCC show a favorable association.
PDAC and LSCC are the cancer types where HIPK2 mass-spec protein most reproducibly stratifies survival.
