Severe congenital neutropenia type 4 (SCN4) is associated with mutations in the G6PC3 gene. To date, all patients bearing the p.Gly260Arg variant of the G6PC3 gene show heart defects. Here, we present a case of the p.Gly260Arg variant in a patient who did not have structural or functional heart anomalies. Treatment with granulocyte colony-stimulating factor recovered the absolute neutrophil count and neutrophil functional competence.
