Across TCGA pan-cancer cohorts, RXFP4 Mutation is linked to patient survival in 4 of 34 cancer types, making it a survival-associated RXFP4 data layer compared with 17 for mass-spec protein.
The strongest signal is observed in lung squamous cell carcinoma (LUSC), where higher RXFP4 Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated RXFP4 expression acts as an unfavorable survival marker, although some lineages such as UCEC and SKCM show a favorable association.
LUSC, PRAD, and UCEC are the cancer types where RXFP4 Mutation most reproducibly stratifies survival.
