Across TCGA pan-cancer cohorts, HNF1B mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated HNF1B data layer compared with 25 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in clear cell renal cell carcinoma (CCRCC), where higher HNF1B mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated HNF1B expression acts as an unfavorable survival marker, although some lineages such as CCRCC and LSCC show a favorable association.
CCRCC, LSCC, and LUAD are the cancer types where HNF1B mass-spec protein most reproducibly stratifies survival.
