[Successful treatment with allogenic hematopoietic stem cell transplantation of a severe congenital neutropenia patient harboring a novel ELANE mutation].

We report a 4-year-old boy with severe congenital neutropenia (SCN), who was successfully treated with hematopoietic stem cell transplantation (HSCT). The patient had frequently developed bacterial infections since 6 months of age, and showed severe neutropenia below 100/μl at 1 year and 4 months of age.
