GATA-3 is one of the three genes mutated in 10% of breast cancers. Nuclear expression of GATA-3 in breast cancer is considered a marker of luminal cancer in ER+ cancer and luminalandrogen responsive cancer in ER-/AR+ tumors. It is highly coexpressed with FOXA1 and serves as negative predictor of basal subtype and HER-2 and is also considered a strong predictor of taxane and platin salts insensitivity. GATA-3 expression is found in urothelial carcinoma, especially in invasive and high grade tumors. Therefore, GATA-3 can be used in a panel of antibodies for diagnosis of unknown primary carcinoma, when carcinomas of the breast or bladder area possibility. Studies have also shown the utility of GATA-3 in differntiatingurothelial carcinoma from prostate adenocarcinoma and squamous cell carcinomas of the uterine, cervix, anus and lung.
