Objectives: Severe congenital neutropenia (SCN) is a primary immunodeficiency (PID) characterized by persistent severe neutropenia, recurrent infections, and oral aphthous lesions. Severe congenital neutropenia is caused by various genetic defects such as ELANE, GFI, HAX-1, JAGN1, SRP54, and glucose-6 phosphatase catalytic subunit 3 (G6PC3) deficiency. Clinical features of the patients with G6PC3 deficiency vary from neutropenia to several systemic features in addition to developmental delay.
