Genes affected

NCF1 (HGNC:7660): (neutrophil cytosolic factor 1) The protein encoded by this gene is a 47 kDa cytosolic subunit of neutrophil NADPH oxidase. This oxidase is a multicomponent enzyme that is activated to produce superoxide anion. Mutations in this gene have been associated with chronic granulomatous disease. [provided by RefSeq, Jul 2008]

NCF1 NM_00265.5 exon 2 p.Ser36= (c.108G>A): This variant has not been reported in the literature but is present in 56/125884 European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/7-74191648-G-A). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. Of note, this variant is a silent variant and does not change the amino acid, reducing the probability that this variant is disease causing. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
