Across TCGA pan-cancer cohorts, EXOC5 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated EXOC5 data layer compared with 26 for mass-spec protein and 4 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher EXOC5 mass-spec protein is associated with better disease-free survival. In most high-consensus cancer types, elevated EXOC5 expression acts as an unfavorable survival marker, although some lineages such as HNSC and UCEC show a favorable association.
HNSC, LUAD, and UCEC are the cancer types where EXOC5 mass-spec protein most reproducibly stratifies survival.
