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. WebNov 2, 2024 · NADPH Oxidase Deficiency: Model of Inheritance Mutations in one of the genes encoding the components of the NADPH oxidase complex cause chronic granulomatous disease (CGD), a rare inherited immunodeficiency syndrome with an estimated frequency of 1/200,000 to 1/250,000 newborns.

WebDec 13, 2016 · INTRODUCTION. Staphylococcus aureus infection is the signature complication of chronic granulomatous disease, a genetic immune deficiency due to a lack of the phagocyte NADPH oxidase. Thus, the phagocyte NADPH oxidase plays a key role in the defense against S. aureus.Yet, this topic has not been comprehensively … WebChronic granulomatous disease is a clinical condition that stems from inactivating mutations in NOX2 and its auxiliary proteins. Together, these proteins form the phagocyte NADPH oxidase enzyme that generates superoxide. Superoxide (O 2ċ–) and its reduced product hydrogen peroxide (H 2 O 2) give rise to several additional reactive oxygen ...
WebJan 29, 2024 · Chronic granulomatous disease (CGD) is a rare inherited primary immunodeficiency due to mutations in any of the critical subunits of the phagocyte NADPH oxidase complex, resulting in impaired oxidase activity of neutrophils, monocytes, and tissue macrophages.

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. Infections caused by the pathogens commonly associated with CGD should prompt functional o…
