Digenic 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...
متن کاملdifferent pattern of gene mutations in iranian patients with severe congenital neutropenia (including 2 new mutations).
severe congenital neutropenia (scn) is a rare primary immunodeficiency disease. different genes are found to be associated with scn, including ela2, hax1, was, gfi1, g-csfr and g6pc3. the aim of this study was to find different gene mutations responsible for scn in iranian patients. twenty-seven patients with scn referred to immunology, asthma and allergy r...
متن کاملSevere congenital neutropenia due to G6PC3 deficiency: early and delayed phenotype in two patients with two novel mutations
Severe Congenital Neutropenia type 4 (SCN4, OMIM 612541) is a rare autosomal recessive disease due to mutations in the G6PC3 gene. The phenotype comprises neutropenia of variable severity and other anomalies including congenital heart defects, prominent superficial veins, uro-genital anomalies, facial dysmorphism, growth and developmental delay and intermittent thrombocytopenia. In some patient...
متن کاملGranulopoiesis 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 کاملHow to approach neutropenia.
Neutropenia is defined as the reduction in the absolute number of neutrophils in the blood circulation. Acute neutropenia is a relatively frequent finding, whereas disorders of production of neutrophils are quite rare. Acute neutropenia is often well tolerated and normalizes rapidly. Neutropenia arising as a result of underlying hematologic disorders is far more significant. Such a patient may ...
