Abstract

Cytopenia is an important indicator of bone marrow failure being common among various disease, specially myelodysplasia and aplastic anemia. Myelodysplasia correspond to a group of clonal marrow disorders, characterized by ineffective hematopoiesis. An important clinical manifestation is a normocellular bone marrow associated with cytopenias. In contrast, aplastic anemia is characterized by a hypocellular bone marrow without neoplastic infiltration and increase in reticulin. The GATA2 gene is a key regulator of hematopoiesis acting on the maintenance of hematopoietic progenitors and stem cell pool. Recently, constitutional mutations in GATA2 gene were described in MonoMac syndrome. This syndrome, eventually, presents cytopenias, hypocellular marrow or even myelodysplasia. However, the contribution of GATA2 mutations on acquired aplastic anemia and myelodysplastic syndrome is not known. In this work is proposed search for mutations on GATA2 gene in patients with acquired aplastic anemia or myelodysplastic syndrome by direct sequencing of DNA. Additionally will be also evaluated the lymphocytic subpopulations in peripheral blood and cytokines levels to correlate with the presence of a GATA2 mutation to an immune profile. (AU)
