Across TCGA pan-cancer cohorts, LIG3 mass-spec protein is linked to patient survival in 6 of 34 cancer types, making it a survival-associated LIG3 data layer compared with 27 for mass-spec protein and 3 for mutation status.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher LIG3 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated LIG3 expression acts as an unfavorable survival marker, although some lineages such as COAD and LSCC show a favorable association.
HNSC, COAD, and LSCC are the cancer types where LIG3 mass-spec protein most reproducibly stratifies survival.
