Across TCGA pan-cancer cohorts, FOXN3 mass-spec protein is linked to patient survival in 3 of 34 cancer types, making it a survival-associated FOXN3 data layer compared with 25 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher FOXN3 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated FOXN3 expression acts as an unfavorable survival marker, although some lineages such as LUAD show a favorable association.
HNSC, LUAD, and LSCC are the cancer types where FOXN3 mass-spec protein most reproducibly stratifies survival.
