Across TCGA pan-cancer cohorts, OR4N4 Mutation is linked to patient survival in 5 of 34 cancer types, making it the most broadly survival-associated OR4N4 data layer compared with 1 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher OR4N4 Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated OR4N4 expression acts as an unfavorable survival marker, although some lineages such as GBM show a favorable association.
HNSC, LUAD, and READ are the cancer types where OR4N4 Mutation most reproducibly stratifies survival.
