A novel G6PC3 gene mutation in severe congenital neutropenia: pancytopenia and variable bone marrow phenotype can also be part of this syndrome

Glucose‐6‐phosphatase catalytic subunit 3 (G6PC3) deficiency is a newly described syndrome characterized by severe congenital neutropenia associated with multiple organ abnormalities including cardiac and urogenital malformations. The underlying pathophysiology of increased apoptosis of myeloid cells and of neutrophil dysfunction in G6PC3 deficiency involves disturbed glucose metabolism, increased endoplasmic reticulum stress and deficient...
