GATA2 gene encodes a zinc finger transcription factor crucial for normal hematopoiesis. Its haploinsufficiency, caused by a great variety of heterozygous loss-of-function mutations, underlies one of the most common causes of inherited bone marrow failure, recognized as GATA2 deficiency. ⋯ The only curative treatment is allogenic hematopoietic stem cell transplantation (HSCT), that can restore the function of both hematopoietic and immune system and prevent lung deterioration. Currently, there are no consensus guidelines about the management of patients affected by GATA2 deficiency, especially with regard to the optimal time to proceed to HSCT.
