Genes affected

CYBA (HGNC:2577): (cytochrome b-245 alpha chain) Cytochrome b is comprised of a light chain (alpha) and a heavy chain (beta). This gene encodes the light, alpha subunit which has been proposed as a primary component of the microbicidal oxidase system of phagocytes. Mutations in this gene are associated with autosomal recessive chronic granulomatous disease (CGD), that is characterized by the failure of activated phagocytes to generate superoxide, which is important for the microbicidal activity of these cells.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 24 of the CYBA protein (p.Gly24Arg). This variant is present in population databases (rs28941476, gnomAD 0.006%). This missense change has been observed in individual(s) with chronic granulomatous disease (PMID: 10759707, 10910929, 19292887, 20167518). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as 98G>A. ClinVar contains an entry for this variant (Variation ID: 2265). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. For these reasons, this variant has been classified as Pathogenic. -
