Chronic granulomatous disease nadph oxidase
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… WebChronic Granulomatous Disease (CGD) Causes.
