Viral and mycobacterial infections are the most commonly encountered pathogens in GATA2 haploinsufficiency.30GATA2 deficiency usually causes cytopenias due to impaired bone marrow haematopoiesis and myelodysplasia, but the elevated levels of autoreactive peripheral CD38− CD21− B cells described in the periphery of GATA2 patients may increase the risk of antibody-mediated autoimmunity,31 and P11 (GATA2 p.T176P) suffered with recurrent Evans syndrome. This evidence concerns the gene GATA2 and Myelodysplasia.
