Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Dec 05, 2023 | This missense variant replaces serine with alanine at codon 137 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). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with RAD51D-related disorders in the literature. 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 13, 2023 | The p.S137A variant (also known as c.409T>G), located in coding exon 5 of the RAD51D gene, results from a T to G substitution at nucleotide position 409. The serine at codon 137 is replaced by alanine, an amino acid with similar properties. 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. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 01, 2023 | 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 not expected to disrupt RAD51D protein function. ClinVar contains an entry for this variant (Variation ID: 472606). This variant has not been reported in the literature in individuals affected with RAD51D-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 137 of the RAD51D protein (p.Ser137Ala). - |
