B3GNT5 and breast carcinoma: We have identified several factors that might predict patient prognosis, including (1) Breast cancer subtypes: B3GNT5 expression is especially elevated in BLBC; (2) Tumor size: high expression of B3GNT5 is correlated with larger tumor size; (3) Tumor grade: high expression of B3GNT5 is associated with high tumor grade; (4) Survival rate: high expression of B3GNT5 predicts poor survival in breast cancer patients.
