Severe congenital neutropenia (SCN) is a rare primary immunodeficiency. Different genes are found to be associated with SCN, including ELA2, HAX1, WAS, GFI1, G-CSFR. Also, recently G6PC3 as a rare gene in SCN has been reported. Patients with G6PC3 often have cardiac and/or urogenital malformations. Two patients with persistent severe neutropenia, recurrent infections and maturation arrest at pr...

BACKGROUND G6PC3 deficiency is a new neutropenic syndrome, which is characterized by severe persistent neutropenia, early onset infections and additional organ involvement, especially cardiac and urogenital malformations. CASE PRESENTATION In this report, we present the clinical details of a recently known case of severe congenital neutropenia (SCN) with G6PC3 mutation, who experienced the fi...

Natural killer (NK) cells are bone marrow (BM)-derived granular lymphocytes involved in immune defense against microbial infections and tumors. In an N-ethyl N-nitrosourea (ENU) mutagenesis strategy, we identified a mouse mutant with impaired NK cell reactivity both in vitro and in vivo. Dissection of this phenotype showed that mature neutrophils were required both in the BM and in the peripher...

Severe congenital neutropenia (SCN) is a disorder of myelopoiesis characterized by severe neutropenia or absence of blood neutrophils secondary to a maturational arrest at the level of promyelocytes. We examined peripheral blood mononuclear cells (PBMC) of SCN patients who demonstrated normalization of their blood neutrophil counts in a phase II clinical study with recombinant human granulocyte...
