Ambry Genetics RCV000571191 SCV000674676 uncertain significance Hereditary cancer-predisposing syndrome 2020-10-09 criteria provided, single submitter clinical testing The p.L226P variant (also known as c.677T>C), located in coding exon 4 of the RAD51C gene, results from a T to C substitution at nucleotide position 677. The leucine at codon 226 is replaced by proline, an amino acid with similar properties. In one study, this variant was reported in 1/3429 patients with epithelial ovarian cancer and 0/2772 controls (Song H et al. J. Clin. Oncol., 2015 Sep;33:2901-7). This variant was also identified in 1/882 Chinese individuals who underwent multi-gene panel testing for HBOC risk assessment (Shao D et al, Cancer Sci., 2020 Feb;111:647-657). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Invitae RCV001068731 SCV001233861 uncertain significance Fanconi anemia complementation group O 2022-12-18 criteria provided, single submitter clinical testing 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. 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 expected to disrupt RAD51C protein function. ClinVar contains an entry for this variant (Variation ID: 486269). This missense change has been observed in individual(s) with breast and/or ovarian cancer (PMID: 26261251, 31742824). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 226 of the RAD51C protein (p.Leu226Pro).
