Across TCGA pan-cancer cohorts, HLA-H Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated HLA-H data layer compared with 26 for mass-spec protein.
The strongest signal is observed in bladder urothelial carcinoma (BLCA), where higher HLA-H Mutation is associated with worse disease-free survival. In most high-consensus cancer types, elevated HLA-H expression acts as an unfavorable survival marker.
BLCA and UCEC are the cancer types where HLA-H Mutation most reproducibly stratifies survival.
