Genes affected

C9 (HGNC:1358): (complement C9) This gene encodes the final component of the complement system. It participates in the formation of the Membrane Attack Complex (MAC). The MAC assembles on bacterial membranes to form a pore, permitting disruption of bacterial membrane organization. Mutations in this gene cause component C9 deficiency.

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 557 of the C9 protein (p.Asn557Ser). This variant is present in population databases (rs138480043, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with C9-related conditions. ClinVar contains an entry for this variant (Variation ID: 1372329). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
