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 RAD51D c.481-8C>T is an intronic variant located close to a canonical splice site. This variant is found in 10/259676 alleles at a frequency of 0.0039% in the gnomAD v2.1.1 database, non-cancer dataset. The SpliceAI algorithm predicts no significant impact on splicing (BP4). To our knowledge, neither relevant clinical data nor well-stablished functional studies have been reported for this variant. It has been reported in the ClinVar database (7x likely benign, 1x uncertain significance) but it has not been identified in LOVD database. Based on the currently available information, c.481-8C>T is classified as an uncertain significance variant according to ACMG guidelines.

Variant summary: RAD51D c.481-8C>T alters a nucleotide located at a position not widely known to affect splicing. 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 1.8e-05 in 1599178 control chromosomes in the gnomAD database (v4.1 dataset). This frequency is not significantly higher than estimated for a pathogenic variant in RAD51D causing Hereditary Breast And Ovarian Cancer Syndrome (0.00013), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.481-8C>T 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: 239398). Based on the evidence outlined above, the variant was classified as likely benign.
