Across TCGA pan-cancer cohorts, FRMD8 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated FRMD8 data layer compared with 27 for mass-spec protein and 2 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher FRMD8 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated FRMD8 expression acts as an unfavorable survival marker, although some lineages such as HNSC and PDAC show a favorable association.
HNSC, PDAC, and CCRCC are the cancer types where FRMD8 mass-spec protein most reproducibly stratifies survival.
