Background: Chronic granuloniatous disease (CGD) is a rare primary immunodeficiency caused by defects in the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase enzyme system. this disease causes the disordered functioning of phagocytic cells. It is characterized by life-threatening and/or recurrent infections by bacteria and fungi. CGD has both an X-linked recessive (X-CGD) and autosomal recessive (AR-CGD) phenotypes. AR form have four subtypes including defects with one of these NADPH oxidase components (p22, p40, p47 and p67(Phox)).
