Description : Severe congenital neutropenia-3 is an autosomal recessive bone marrow failure disorder
characterized by low numbers of neutrophils, increased susceptibility to bacterial
and fungal infections, and increased risk of developing myelodysplastic syndrome or
acute myeloid leukemia. In addition, patients with HAX1 mutations affecting both isoform
A and B of the gene develop neurologic abnormalities (summary by Boztug et al., 2010).
The Swedish physician Rolf Kostmann (1956) described an autosomal recessive hematologic
disorder, termed infantile agranulocytosis, with severe neutropenia with an absolute
neutrophil count below 0.5 x 10(9)/l and early onset of severe bacterial infections.
The disorder was later termed Kostmann syndrome (Skokowa et al., 2007). Lekstrom-Himes
and Gallin (2000) discussed severe congenital neutropenia in a review of immunodeficiencies
caused by defects in phagocytes. In addition to Kostmann agranulocytosis, recessively
inherited neutropenic syndromes include congenital neutropenia with eosinophilia (257100),
Chediak-Higashi syndrome (214500), and Fanconi pancytopenic syndrome (see 227650).
For a phenotypic description and a discussion of genetic heterogeneity of severe congenital
neutropenia, see SCN1 (202700).;
