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.
