Hereditary cancer-predisposing syndrome Uncertain:2
This missense variant replaces isoleucine with threonine at codon 311 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 not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 2/251488 chromosomes 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. -
The p.I311T variant (also known as c.932T>C), located in coding exon 10 of the RAD51D gene, results from a T to C substitution at nucleotide position 932. The isoleucine at codon 311 is replaced by threonine, an amino acid with similar properties. This variant was observed in an individual with early onset-breast cancer amongst a cohort of 1781 non-Ashkenazi Jewish individuals undergoing BRCA1/2 gene testing based on a personal history of breast cancer (Tung N et al. Cancer, 2015 Jan;121:25-33). This amino acid position is well 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. -
not provided Uncertain:1
In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Breast-ovarian cancer, familial, susceptibility to, 4 Uncertain:1
This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 311 of the RAD51D protein (p.Ile311Thr). This variant is present in population databases (rs145309168, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with RAD51D-related conditions. ClinVar contains an entry for this variant (Variation ID: 127897). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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. -
