Across TCGA pan-cancer cohorts, BMPR1B mass-spec protein is linked to patient survival in 1 of 34 cancer types, making it a survival-associated BMPR1B data layer compared with 22 for mass-spec protein and 5 for mutation status.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher BMPR1B mass-spec protein is associated with better overall survival. In most high-consensus cancer types, elevated BMPR1B expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
UCEC are the cancer types where BMPR1B mass-spec protein most reproducibly stratifies survival.
