Across TCGA pan-cancer cohorts, SNAI2 mass-spec protein is linked to patient survival in 4 of 34 cancer types, making it a survival-associated SNAI2 data layer compared with 27 for mass-spec protein and 1 for mutation status.
The strongest signal is observed in pancreatic ductal adenocarcinoma (PDAC), where higher SNAI2 mass-spec protein is associated with worse disease-free survival. In most high-consensus cancer types, elevated SNAI2 expression acts as an unfavorable survival marker, although some lineages such as HNSC show a favorable association.
PDAC, HNSC, and UCEC are the cancer types where SNAI2 mass-spec protein most reproducibly stratifies survival.
