Across TCGA pan-cancer cohorts, HS3ST4 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated HS3ST4 data layer compared with 23 for mass-spec protein.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher HS3ST4 Mutation is associated with better disease-free survival. In most high-consensus cancer types, elevated HS3ST4 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
UCEC, READ, and LIHC are the cancer types where HS3ST4 Mutation most reproducibly stratifies survival.
