|Title||Heritable GATA2 mutations associated with familial myelodysplastic syndrome and acute myeloid leukemia.|
|Abstract Text||We report the discovery of GATA2 as a new myelodysplastic syndrome (MDS)-acute myeloid leukemia (AML) predisposition gene. We found the same, previously unidentified heterozygous c.1061C>T (p.Thr354Met) missense mutation in the GATA2 transcription factor gene segregating with the multigenerational transmission of MDS-AML in three families and a GATA2 c.1063_1065delACA (p.Thr355del) mutation at an adjacent codon in a fourth MDS family. The resulting alterations reside within the second zinc finger of GATA2, which mediates DNA-binding and protein-protein interactions. We show differential effects of the mutations on the transactivation of target genes, cellular differentiation, apoptosis and global gene expression. Identification of such predisposing genes to familial forms of MDS and AML is critical for more effective diagnosis and prognosis, counseling, selection of related bone marrow transplant donors and development of therapies.|

|GATA2||L359V||missense||unknown||GATA2 L359V lies within the GATA-type zinc finger domain 2 of the Gata2 protein (UniProt.org). L359V results in failure to inhibit colony formation in culture (PMID: 28642594), enhanced inhibition of the regulatory element, Spi1, altering monocytic differentiation (PMID: 18250304), differential regulation of gene expression (PMID: 21892162), and reduced transactivation activity in a reporter assay in one study (PMID: 26214525), however, in other studies demonstrates transactivation levels similar to wild-type or higher than wild-type (PMID: 28642594, PMID: 22649106, PMID: 21892162), and maintains inhibition of proliferation and apoptosis in cell culture (PMID: 21892162), and therefore, its effect on Gata2 protein function is unknown.|
|GATA2||T354M||missense||loss of function||GATA2 T354M lies within the GATA-type zinc finger domain 2 of the Gata2 protein (UniProt.org). T354M results in reduced binding of Gata2 to DNA (PMID: 26214525), inhibition of cell differentiation and apoptosis (PMID: 21892162), and decreased transcriptional activation, leading to increased myeloid proliferation and colony formation in culture (PMID: 30301799).|
