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.

Variant summary: RAD51D c.919G>A (p.Glu307Lys) results in a conservative amino acid change located in the DNA recombination and repair protein Rad51-like, C-terminal domain of the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant was found in 78/277234 control chromosomes in gnomAD, but was observed primarily in the African subpopulation (70/24038 control chromosomes). The frequency within the African control individuals is more than 23-fold above the estimated maximal expected allele frequency for a pathogenic variant in RAD51D causing Hereditary Breast and Ovarian Cancer phenotype (0.00013). In addition, this variant has been found in 21/2559 African American women who are 70 years old or older and are cancer-free. These evidence strongly suggests that the variant is a benign polymorphism found primarily in populations of African origin. c.919G>A has been reported in the literature in individuals affected with Hereditary Breast and Ovarian Cancer without strong evidence for causality. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 with conflicting assessments including uncertain significance (2x) and likely benign (2x). Based on the evidence outlined above, the variant was classified as benign. -

RAD51D, EXON10, c.919G>A, p.Glu307Lys, Heterozygous, Likely Benign The RAD51D p.Glu307Lys variant was identified in 2 of 4316 proband chromosomes (frequency: 0.0005) from individuals or families with breast cancer (Tung 2015). The variant was also identified in dbSNP (ID: rs115031549) as "With Uncertain Significance allele", in ClinVar with Conflicting interpretations of pathogenicity (as Benign by Integrated Genetics and Colour, as Likely benign by Invitae and Ambry and as Uncertain significance by Mendelics, Quest, GeneDx and EGL Genetics). The variant was identified in control databases in 78 of 277234 chromosomes at a frequency of 0.0003 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 70 of 24038 chromosomes (freq: 0.003), Other in 1 of 6468 chromosomes (freq: 0.0002), Latino in 7 of 34420 chromosomes (freq: 0.0002), but was not observed in the European Non-Finnish, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The p.Glu307 residue is conserved in in mammals but not in more distantly related organisms however computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; this information is not predictive enough to rule out 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 although we would lean towards a more benign role for this variant. This variant is classified as likely benign. Assessment Date: 2019/07/29 -

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following: it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease, and/or has normal protein function, and/or has lack of segregation with disease, and/or has been detected in co-occurrence with known pathogenic variant, and/or has lack of disease association in case-control studies, and/or is located in a region inconsistent with a known cause of pathogenicity. -
