Across TCGA pan-cancer cohorts, HNF1B Mutation 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 mass-spec protein.
The strongest signal is observed in stomach adenocarcinoma (STAD), where higher HNF1B Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated HNF1B expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
STAD, LUAD, and UCEC are the cancer types where HNF1B Mutation most reproducibly stratifies survival.
