GATA2 mutations in myeloid malignancies: Two zinc fingers in many pies

Abstract

The GATA family of transcription factors are zinc finger (ZF) DNA-binding proteins that regulate transcription during development and cell differentiation. GATA2 plays an essential role in the regulation of hematopoiesis. As a result, mutations in this gene or alterations in its expression level or function have been linked to a variety of human hematologic disorders. In this review, we summarize the findings and developments over the recent years regarding the clinical correlations and functional properties of distinct GATA2 mutations in hematopoietic malignancies, with particular focus on the mutational hotspots in the ZF domains.
