Cardiac and renal malformations in a patient with sepsis and severe congenital neutropenia.
BACKGROUND
G6PC3 deficiency is a new neutropenic syndrome, which is characterized by severe persistent neutropenia, early onset infections and additional organ involvement, especially cardiac and urogenital malformations.


METHODS
In this report, we present the clinical details of a recently known case of severe congenital neutropenia (SCN) with G6PC3 mutation, who experienced the first episode of infections at birth. Repeated absolute neutrophil count of less than 500/µl was detected during work-up of sepsis in the first month of life. SCN was diagnosed and granulocyte colony-stimulating factor (GCSF) administration initiated. Bone marrow examination revealed maturation arrest in myeloid series at promyelocyte-myelocyte stage. Diarrhea, bronchiolitis, and urinary tract infection were other infectious complications, while hydronephrosis, atrial septal defect, and patent ductus arteriosus were other manifestations.


CONCLUSIONS
Prompt and accurate diagnosis of neutropenic patients and appropriate treatment can prevent further complications and improve the quality of life of the affected patients.
