A disorder arising from deficiency in the GATA2 with a wide spectrum of phenotypes. Autosomal dominant mutations of GATA2 cause a haploinsufficiency, which, in consequence, cause individuals to develop hematological, immunological, lymphatic, or other presentations. These often progress to severe organ (e.g. lung) failure, opportunistic infections, myelodysplastic syndrome, and/or acute myeloid leukemia. The most common clinical denominator is the propensity for myeloid neoplasia (myelodysplastic syndrome [MDS], myeloproliferative neoplasms [MPN], chronic myelomonocytic leukemia [CMML], acute myeloid leukemia [AML]).
