Across TCGA pan-cancer cohorts, IGSF6 mass-spec protein is linked to patient survival in 5 of 34 cancer types, making it a survival-associated IGSF6 data layer compared with 22 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher IGSF6 mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated IGSF6 expression acts as an unfavorable survival marker, although some lineages such as HNSC and LSCC show a favorable association.
HNSC, PDAC, and UCEC are the cancer types where IGSF6 mass-spec protein most reproducibly stratifies survival.
