Abstract

Introduction: Severe congenital neutropenia (SCN) includes a group of genetic disorders which cause to arrest of neutrophil maturation. SCN can be associated with heterogenous group of genetic defects in ELANE, GFI1, HAX1, G6PC3, JAGN1, VPS45 or activating mutations in the Wiskott-Aldrich syndrome (WAS) gene. Aim: Here we report a patient who has a HAX1 mutation presented with cyclic manner. Case Report: A 6 year old female patients was admitted with recurrent apthous stomatitis. We followed the patient as cyclic neutropenia according to complete blood count results 2 times for 6 weeks. After persistant neutropenia developed during a severe varicella infection, we analysed HAX1 mutation, the result was interesting and incompatible with reported cyclic neutropenia patients. Conclusion: We suggest that HAX1 deficiency should be thought in patients who have normal neutrophil counts in the between of infections.
