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:3

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Dec 14, 2023	This sequence change creates a premature translational stop signal (p.His250Thrfs*2) 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 (rs587780105, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with breast and ovarian cancer (PMID: 25452441, 26261251). ClinVar contains an entry for this variant (Variation ID: 127894). For these reasons, this variant has been classified as Pathogenic. -

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Sep 19, 2022	This variant deletes 1 nucleotide in exon 9 of the RAD51D gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been observed in five individuals affected with ovarian cancer, including three individuals from the same family (PMID: 26261251, 33008098). This variant has been reported in an individual with triple-negative breast cancer (PMID: 25452441). This variant has been identified in 1/251058 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	Oct 06, 2021	The c.748delC pathogenic mutation, located in coding exon 9 of the RAD51D gene, results from a deletion of one nucleotide at nucleotide position 748, causing a translational frameshift with a predicted alternate stop codon (p.H250Tfs*2). This mutation has been detected in multiple breast and/or ovarian cancer cohorts (Couch FJ et al. J Clin Oncol, 2015 Feb;33:304-11; Susswein LR et al. Genet Med, 2016 08;18:823-32; Barbosa A et al. Cancers (Basel), 2020 Sep;12), as well as in a prostate cancer patient (Wu Y et al. Eur Urol Oncol, 2020 04;3:224-230). In one study, this variant was reported in 2/60,466 breast cancer cases and in 2/53,461 controls (Dorling et al. N Engl J Med. 2021 02;384:428-439). 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. -
