Ambry Genetics | RCV000166827 | SCV000217641 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-09-22 | criteria provided, single submitter | clinical testing | The p.A308G variant (also known as c.923C>G), located in coding exon 7 of the RAD51C gene, results from a C to G substitution at nucleotide position 923. The alanine at codon 308 is replaced by glycine, an amino acid with some similar properties. This variant was identified in a cohort of 3,579 African males diagnosed with prostate cancer who underwent multi-gene panel testing of 19 DNA repair and cancer predisposition genes (Matejcic M et al. JCO Precis Oncol 2020 Jan;4:32-43). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |

RCV000470112 | SCV000550225 | uncertain significance | Fanconi anemia complementation group O | 2024-01-02 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 308 of the RAD51C protein (p.Ala308Gly). This variant is present in population databases (rs786203498, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with RAD51C-related conditions. ClinVar contains an entry for this variant (Variation ID: 187133). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt RAD51C protein function with a negative predictive value of 80%. 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. |

RCV004528918 | SCV004104655 | uncertain significance | RAD51C-related disorder | 2022-10-05 | criteria provided, single submitter | clinical testing | The RAD51C c.923C>G variant is predicted to result in the amino acid substitution p.Ala308Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/17-56801419-C-G). This variant is interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/187133/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
