Across TCGA pan-cancer cohorts, CLSTN1 Mutation is linked to patient survival in 5 of 34 cancer types, making it a survival-associated CLSTN1 data layer compared with 21 for mass-spec protein and 6 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher CLSTN1 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated CLSTN1 expression acts as an unfavorable survival marker, although some lineages such as STAD show a favorable association.
HNSC, BLCA, and SKCM are the cancer types where CLSTN1 Mutation most reproducibly stratifies survival.
