Granulopoiesis in severe congenital neutropenia.
The pathogenesis of the granulopoietic failure in three children with severe congenital neutropenia was studied. Mature neutrophils were absent from both peripheral blood and bone marrow. Assay of bone marrow granulocyte colony-forming cells (CFU-C) in a methylcellulose tissue culture system using colony-stimulating activity (CSA) from peripheral blood leukocytes demonstrated normal or increase...
متن کاملA comparison of the defective granulopoiesis in childhood cyclic neutropenia and in severe congenital neutropenia.
BACKGROUND AND OBJECTIVES Cyclic neutropenia (CyN) in childhood and severe congenital neutropenia (SCN) are congenital disorders that cause chronic neutropenia. Mutations in the neutrophil elastase gene, ELA2, have been reported in patients with CyN and in those with SCN. We examined granulopoietic defects in CyN patients with those in SCN patients. DESIGN AND METHODS Three patients with CyN ...
متن کاملMice expressing a neutrophil elastase mutation derived from patients with severe congenital neutropenia have normal granulopoiesis.
Severe congenital neutropenia (SCN) is a syndrome characterized by an isolated block in granulocytic differentiation and an increased risk of developing acute myeloid leukemia (AML). Recent studies have demonstrated that the majority of patients with SCN and cyclic neutropenia, a related disorder characterized by periodic oscillations in the number of circulating neutrophils, have heterozygous ...
متن کاملSevere congenital neutropenia: case report
Introduction Neutropenia is defined in the literature as absolute neutrophil counts in peripheral blood of less than 1500 cells/mm3 in more than one year old and less than 2000cells/mm3 in children in the first year old of life. Neutropenia is classified as mild, moderate or severe, and may be congenital or acquired, persistent or not. Kostmann syndrome is a severe neutropenia, the incidence va...
متن کاملDigenic mutations in severe congenital neutropenia.
Severe congenital neutropenia a clinically and genetically heterogeneous disorder. Mutations in different genes have been described as causative for severe neutropenia, e.g. ELANE, HAX1 and G6PC3. Although congenital neutropenia is considered to be a group of monogenic disorders, the phenotypic heterogeneity even within the yet defined genetic subtypes points to additional genetic and/or epigen...
