摘要

Causative homozygous or compound heterozygous mutations in the glucose-6-phosphatase, catalytic subunit 3 gene (G6PC3) have recently been described for a sub-group of patients with severe congenital neutropenia (SCN) (Arostegui et al, 2009; Boztug et al, 2009, 2011; Xia et al, 2009; Germes-hausen et al, 2010; Banka et al, 2011a,b; Hayee et al, 2011). In addition to neutropenia and recurrent infections, mutant-positive patients are reported to have varied other congenital abnormalities, such as a prominent superficial venous pattern, structural heart defects, urogenital malformations, skeletal abnormalities, primary pulmonary hypertension, growth and developmental delay (Boztug et al, 2011). Several reports have also indicated considerable variation in bone marrow (BM) morphology, including a lack of the myeloid maturation arrest characteristic of SCN (McDermott et al, 2010; Banka et al, 2011b).
