Abstract :
Chronic granulomatous disease (CGD) is a rare primary immunodeficiency disorder due to a genetic defect in one of the components of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. This complex is composed of membrane-bound gp91-phox and p22-phox subunits, and cytosolic subunits consisting of p47-phox, p67-phox, and p40-phox. A mutation in CYBB gene encoding gp91-phox located on chromosome Xp21.1, leads to X-linked CGD. Herein, we report a 4-year-old Iranian boy presented with episodes of recurrent fever, cervical lymphadenopathy, and abdominal abscesses. Mutation analysis of the CYBB gene in the patient indicated a one-nucleotide deletion, c.316delT, resulting in p.W106GfsX.
