Across TCGA pan-cancer cohorts, GPR18 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated GPR18 data layer compared with 25 for mass-spec protein and 1 for mass-spec protein.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher GPR18 Mutation is associated with better disease-free survival. In most high-consensus cancer types, elevated GPR18 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
UCEC, READ, and LUSC are the cancer types where GPR18 Mutation most reproducibly stratifies survival.
