Across TCGA pan-cancer cohorts, PKNOX2 Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated PKNOX2 data layer compared with 24 for mass-spec protein and 3 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher PKNOX2 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PKNOX2 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
HNSC, OV, and SARC are the cancer types where PKNOX2 Mutation most reproducibly stratifies survival.
