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. [provided by RefSeq, Feb 2009]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Nov 25, 2022 | 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with C9-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change results in a frameshift in the C9 gene (p.Asn557Metfs*46). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 3 amino acid(s) of the C9 protein and extend the protein by 42 additional amino acid residues. - |
