WebMay 12, 2024 · Abstract The leukocyte NADPH oxidase 2 (NOX2) plays a key role in pathogen killing and immunoregulation. Genetic defects in NOX2 result in chronic granulomatous disease (CGD), associated with microbial infections and inflammatory disorders, often involving the lung. WebChronic granulomatous disease (CGD) is an immunodeficiency disorder affecting about 1 in 250,000 individuals. The disease is caused by a lack of superoxide production by the leukocyte enzyme NADPH oxidase. Superoxide is used to kill phagocytosed micro-organisms in neutrophils, eosinophils, monocytes and macrophages.
WebOct 19, 2011 · Chronic granulomatous disease (CGD) is a rare primary immunodeficiency due to an abnormal function of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase; NADPH oxidase is a key enzyme for the cellular “respiratory burst”, the cellular process that converts molecular oxygen to the oxygen free-radical superoxide. Chronic Granulomatous Disease (CGD) Causes. CGD is caused by defects in an enzyme, NADPH oxidase, that phagocytes need to kill certain bacteria and fungi. Symptoms & Diagnosis.

When chronic granulomatous disease (CGD) is suspected, neutrophil-function testing should be carried out, and positive findings should be confirmed by genotyping. The p47phox mutation is due to a pseudogene conversion, hence it may not be detectable by standard sequencing; in these cases, an immunoblot or gene dose determination may be needed to confirm p47phox deficiency.
