Across TCGA pan-cancer cohorts, HSPA1A Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated HSPA1A data layer compared with 21 for mass-spec protein.
The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where higher HSPA1A Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated HSPA1A expression acts as an unfavorable survival marker.
HNSC, KICH, and ESCA are the cancer types where HSPA1A Mutation most reproducibly stratifies survival.
