Discussion: Both patients had GATA2 deficiency with Emberger syndrome (MDS and lymphedema) and monosomy of 7, as well as mutations in ASXL1 and SETBP1. The immunophenotyping of both is characteristic, with a reduction in precursors and B lymphocytes, in addition to monocytopenia. Here, SETBP1 is linked to myelodysplastic syndrome.
