Genes affected
RAD51D (HGNC:9823): (RAD51 paralog D) The protein encoded by this gene is a member of the RAD51 protein family. RAD51 family members are highly similar to bacterial RecA and Saccharomyces cerevisiae Rad51, which are known to be involved in the homologous recombination and repair of DNA. This protein forms a complex with several other members of the RAD51 family, including RAD51L1, RAD51L2, and XRCC2. The protein complex formed with this protein has been shown to catalyze homologous pairing between single- and double-stranded DNA, and is thought to play a role in the early stage of recombinational repair of DNA. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the downstream ring finger and FYVE-like domain containing 1 (RFFL) gene.

Uncertain significance, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The RAD51D p.Arg239Trp variant was identified in 8 of 10584 proband chromosomes (frequency: 0.0008) from individuals or families with breast or ovarian cancer and was not identified in 5624 control chromosomes from healthy individuals (Gutierrez-Enriquez 2013, Sanchez-Bermudez 2018, Song 2015, Wickramanayake 2012). The variant was also identified in several population studies with a co-occurring pathogenic RAD51D variant (c.694C>T, p.Arg232*) in multiple members of same families (Sanchez-Bermudez 2018, Gutierrez-Enriquez 2013, Wickramanayake 2012). The variant was also identified in dbSNP (ID: rs770250516) as "With Uncertain significance allele", and in ClinVar (classified as uncertain significance by Invitae, Ambry Genetics and four other submitters). The variant was identified in control databases in 9 of 271100 chromosomes at a frequency of 0.00003 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 1 of 6340 chromosomes (freq: 0.0002), European in 5 of 123902 chromosomes (freq: 0.00004), East Asian in 2 of 18598 chromosomes (freq: 0.0001), and South Asian in 1 of 29868 chromosomes (freq: 0.00003), while the variant was not observed in the African, Latino, Ashkenazi Jewish, or Finnish populations. The p.Arg239 residue is conserved in mammals but not in more distantly related organisms, and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 27, 2024This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 239 of the RAD51D protein (p.Arg239Trp). This variant is present in population databases (rs770250516, gnomAD 0.01%). This missense change has been observed in individual(s) with ovarian cancer (PMID: 22986143, 24130102, 26261251, 29409816). ClinVar contains an entry for this variant (Variation ID: 187225). 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. -

Hereditary cancer-predisposing syndrome Uncertain:1Benign:2
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 23, 2022The p.R239W variant (also known as c.715C>T), located in coding exon 8 of the RAD51D gene, results from a C to T substitution at nucleotide position 715. The arginine at codon 239 is replaced by tryptophan, an amino acid with dissimilar properties. This alteration is reported to co-occur with the p.R232* (c.694C>T) pathogenic RAD51D mutation in a proband with ovarian cancer at age 43 (Wickramanyake A et al. Gynecol. Oncol. 2012 Dec;127:552-5). In another family, both alterations were found in a proband with ovarian cancer at age 44 and in four of her healthy siblings (Gutiérrez-Enríquez S et al. Int. J. Cancer. 2014 May;134:2088-97). Both of these alteration are also reported in a third family with two sisters with ovarian cancer at ages 47 and 46 and their three unaffected children (Sanchez-Bermudez AI et al. Eur J Med Genet. 2018 Jun;61(6):355-361). This variant was reported in 1/3429 patients with invasive epithelial ovarian cancer and 0/2772 controls (Song H et al. J. Clin. Oncol. 2015 Sep;33:2901-7). 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. -
