GATA3 Information for Pathologists
Summary:One of 6 members of the GATA family of transcription factors. Involved in the luminal differentiation of breast epithelium, development of collecting system / urothelium and trophoblastic differentiation. Also master regulator of type 2 helper T cells. Essential features Nuclear marker with expression in many epithelial neoplasms (including most breast, urothelial, paraganglioma / pheochromocytoma and skin carcinoma; smaller percentages of lung, liver, pancreatic, gastric, renal, thyroid, endometrial, ovarian and salivary gland carcinoma).
Notable Clinical Features:GATA3 mutations cause HDR (hypoparathyroidism, sensorineural deafness and renal dysplasia) syndrome (Ann N Y Acad Sci 2011;1237:24, Endocr J 2011;58:117). Uses by pathologists Differentiate metastatic urothelial and breast carcinomas (GATA3+) from many other metastatic carcinomas (Am J Surg Pathol 2014;38:13). Differentiate urothelial carcinoma (> 80% GATA3+) from prostatic carcinoma (2% GATA3+). Differentiate metastatic lobular carcinoma of the breast (GATA3+) from gastric signet ring cell carcinoma (GATA3-).
Common Uses By Pathologists:Differentiate metastatic urothelial and breast carcinomas (GATA3+) from many other metastatic carcinomas (Am J Surg Pathol 2014;38:13). Differentiate urothelial carcinoma (> 80% GATA3+) from prostatic carcinoma (2% GATA3+). Differentiate metastatic lobular carcinoma of the breast (GATA3+) from gastric signet ring cell carcinoma (GATA3-). Differentiate squamous cell carcinoma of the skin (GATA3+) from squamous cell carcinoma of the lung (GATA3-). Differentiate mesothelioma (81% GATA3+) from pulmonary adenocarcinoma (12% GATA3+).
