Across TCGA pan-cancer cohorts, UBR1 Mutation is linked to patient survival in 2 of 34 cancer types, making it a survival-associated UBR1 data layer compared with 26 for mass-spec protein and 7 for mass-spec protein.
The strongest signal is observed in uterine corpus endometrial carcinoma (UCEC), where higher UBR1 Mutation is associated with better disease-free survival. In most high-consensus cancer types, elevated UBR1 expression acts as an unfavorable survival marker, although some lineages such as UCEC show a favorable association.
UCEC and COAD are the cancer types where UBR1 Mutation most reproducibly stratifies survival.
