Hereditary cancer-predisposing syndrome Uncertain:2
The p.G315E variant (also known as c.944G>A), located in coding exon 10 of the RAD51D gene, results from a G to A substitution at nucleotide position 944. The glycine at codon 315 is replaced by glutamic acid, an amino acid with similar properties. In one study, this alteration was identified in 1/2772 control individuals and was not observed in 3429 ovarian cancer cases (Song H et al. J Clin Oncol, 2015 Sep;33:2901-7). This alteration was detected in a German cohort of 5589 BRCA1/2-negative probands with breast cancer (Hauke J et al. Cancer Med, 2018 Apr;7:1349-1358) and in a cohort of 690 patients with myeloid malignancy (Li ST et al. Leukemia, 2020 Jun;34:1675-1678). 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. -
This missense variant replaces glycine with glutamic acid at codon 315 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 been detected in a breast cancer case-control meta-analysis in 0/60466 cases and 1/53461 unaffected individuals (PMID: 33471991; Leiden Open Variation Database DB-ID RAD51D_000066) and in a ovarian cancer case-control study in 1/2772 unaffected individuals and absent in 3429 cases (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. -
Breast-ovarian cancer, familial, susceptibility to, 4 Uncertain:1
This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 315 of the RAD51D protein (p.Gly315Glu). This variant is not present in population databases (gnomAD no frequency). 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: 186687). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
