Across TCGA pan-cancer cohorts, HOXD9 Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated HOXD9 data layer compared with 22 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in stomach adenocarcinoma (STAD), where higher HOXD9 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated HOXD9 expression acts as an unfavorable survival marker, although some lineages such as SKCM show a favorable association.
STAD, LIHC, and PAAD are the cancer types where HOXD9 Mutation most reproducibly stratifies survival.
