Severe congenital neutropenia-7 is an autosomal recessive immunodeficiency characterized by onset of recurrent infections in infancy or early childhood. Patients have peripheral neutropenia, although bone marrow biopsy shows normal granulocyte maturation. The neutropenia is not responsive to treatment with G-CSF, but may be responsive to GM-CSF (summary by Triot et al., 2014 and Klimiankou et al., 2015).
For a general phenotypic description and a discussion of genetic heterogeneity of severe congenital neutropenia, see SCN1 (202700). [from
