For TGFB2-dependent biomarkers, elevated TGFB2 mRNA expression is a prognostic biomarker associated with breast cancer patients that is correlated with improved OS outcomes at high expression levels of GDAP1, TBL1XR1, RNFT1, HACL1, SLC27A2, NLE1, and TXNDC16. The gene discussed is GDAP1; the disease is breast cancer.
