PTGIR

Across TCGA pan-cancer cohorts, PTGIR Mutation is linked to patient survival in 3 of 34 cancer types, making it a survival-associated PTGIR data layer compared with 24 for mass-spec protein.

The strongest signal is observed in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), where higher PTGIR Mutation is associated with worse overall survival. In most high-consensus cancer types, elevated PTGIR expression acts as an unfavorable survival marker.

CESC, ESCA, and UCEC are the cancer types where PTGIR Mutation most reproducibly stratifies survival.

Mutation survival associations by lineage

Ranked by sampling consensus. AUC1 and AUC2 indicate survival in the high- and low-expression groups, respectively; the lower AUC marks the poorer-surviving group. p-values are from the log-rank test.
