Severe congenital neutropenia (SCN), a heterogeneous disorder that includes Kostmann syndrome, predisposes to myelodysplasia and acute myelogenous leukemia. Recently identified heterozygous mutations in the gene ELA2, encoding neutrophil elastase on human chromosome 19pter, account for the majority of autosomal dominant cases of SCN, including those demonstrating neoplastic progression. The involvement of the serine protease neutrophil elastase, localized to the granules of neutrophils and monocytes, implies an unexpected role for proteolytic regulation of hematopoiesis. Continued elucidation of the clinical features, molecular genetics, and biochemistry is likely to provide insight into novel pathways of leukemia induction with attendant prospects for new avenues of therapy.

The growth factor independence-1 (Gfi1) transcription factor is required for proper development of neuroendocrine cells, sensory neurons, and blood. Patients with mutations in Gfi1 exhibit severe congenital neutropenia (SCN) or non-immune chronic idiopathic neutropenia of adults. Gfi1 was initially described as an oncoprotein that mediates tumor progression in a mouse model of leukemia; however, recent data suggest that Gfi1 may act as either an oncogene or an anti-proliferative tumor suppressor gene depending on the cell type. Here we review the latest literature on Gfi1, and emphasize its role in the hematopoietic, sensory and neuroendocrine systems.

Severe congenital neutropenia (SCN), originally described by the Swedish pediatrician Rolf Kostmann, constitutes a heterogeneous disorder associated with a dramatic decrease of peripheral neutrophil granulocytes. Patients suffer from life-threatening bacterial infections unless treated by recombinant human granulocyte colony stimulating factor (G-CSF) or allogeneic hematopoietic stem cells. This review is focused on the SCN variant caused by mutations in HCLS1 Associated Protein X-1 (HAX1) (SCN3, "Kostmann Disease"). HAX1 is a ubiquitously expressed protein with pleotropic functions, including control of cellular viability, migration, and cancer progression. Even though scientific evidence on the molecular mechanisms regarding HAX1 accumulates, no unified picture has emerged. This review highlights historical milestones and our current understanding of SCN related to mutations in HAX1.
