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.

BP4, BP7 c.263+7G>A is an intronic variant not very close to a canonical splice site, where the SpliceAI algorithm predicts no significant impact on splicing (BP4 and BP7). This variant is found in 6/268236 alleles at a frequency of 0.0022% in the gnomAD v2.1.1 database, non-cancer dataset. To our knowledge, neither relevant clinical data nor functional studies have been reported for this variant. It has been identified in a patient affected with breast cancer (internal data). It has only been reported in ClinVar (8x as likely benign). Based on currently available information, the variant c.263+7G>A should be considered a likely benign variant. -

Variant summary: RAD51D c.263+7G>A alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 2.4e-05 in 1605330 control chromosomes, predominantly at a frequency of 0.0003 within the Latino subpopulation in the gnomAD database (v4.1 dataset). The observed variant frequency within Latino control individuals in the gnomAD database is approximately 2.4-fold of the estimated maximal expected allele frequency for a pathogenic variant in RAD51D causing Hereditary Breast And Ovarian Cancer Syndrome phenotype (0.00013). To our knowledge, no occurrence of c.263+7G>A in individuals affected with Hereditary Breast And Ovarian Cancer Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 384514). Based on the evidence outlined above, the variant was classified as benign. -

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 criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
