Retraction of Aprikyan et al.

Re: Aprikyan A, Carlsson G, Stein S, et al. Neutrophil Elastase Mutations in Severe Congenital Neutropenia Patients of the Original Kostmann Family. Blood First Edition Paper, prepublished online January 16, 2003; DOI 10.1182/blood-2002-04-1255. The authors respectfully withdraw this paper from final publication consideration. As noted in the journal's published Notice of Investigation, errors in some of the digital images in the manuscript are under investigation. Additional findings concerning patient data make some of the conclusions of our report uncertain. We therefore retract the prepublished paper and extend our deepest apologies to the scientific community.
