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.

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Dec 29, 2023	This sequence change creates a premature translational stop signal (p.Trp268*) in the RAD51D gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RAD51D are known to be pathogenic (PMID: 21822267). This variant is present in population databases (rs750219200, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with ovarian cancer (PMID: 21822267, 23372765). ClinVar contains an entry for this variant (Variation ID: 410552). For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Sep 19, 2022	This variant changes 1 nucleotide in exon 9 of the RAD51D gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in individuals affected with ovarian cancer (PMID: 21822267, 23372765, 25445424 ). This variant has been identified in 2/251428 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of RAD51D function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 06, 2021	The p.W268* pathogenic mutation (also known as c.803G>A), located in coding exon 9 of the RAD51D gene, results from a G to A substitution at nucleotide position 803. This changes the amino acid from a tryptophan to a stop codon within coding exon 9. This alteration has been reported in one proband diagnosed with ovarian cancer at age 58, who had a family history of breast, ovarian and colon cancer (Loveday C et al. Nat. Genet. 2011 Sep;43(9):879-82). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -

Variant summary: RAD51D c.803G>A (p.Trp268X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 8e-06 in 251428 control chromosomes. c.803G>A has been reported in the literature in individuals affected with Ovarian cancer (example: Loveday_2011, etc). Six submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
