Color Diagnostics, LLC DBA Color Health RCV001176994 SCV001341099 uncertain significance Hereditary cancer-predisposing syndrome 2019-10-18 criteria provided, single submitter clinical testing This missense variant replaces glycine with aspartic acid at codon 218 of the RAD51D protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has been reported in 1 individual affected with ovarian cancer (PMID: 26261251). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
Labcorp Genetics (formerly Invitae), Labcorp RCV003528270 SCV004297752 uncertain significance Breast-ovarian cancer, familial, susceptibility to, 4 2024-01-17 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 218 of the RAD51D protein (p.Gly218Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with ovarian cancer (PMID: 26261251). ClinVar contains an entry for this variant (Variation ID: 919068). 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 RAD51D 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.
