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:4

Pathogenic, criteria provided, single submitter	clinical testing	GeneDx	Oct 22, 2018	This duplication of one nucleotide is denoted RAD51D c.326dupC at the cDNA level and p.Gly110ArgfsX2 (G110RfsX2) at the protein level. The normal sequence, with the base that is duplicated in brackets, is GGCCC[dupC]AGGT. The duplication causes a frameshift, which changes a Glycine to an Arginine at codon 110, and creates a premature stop codon at position 2 of the new reading frame. This variant is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. RAD51D c.326dupC has been identified in an individual with breast and/or ovarian cancer and in an individual with prostate cancer (Maxwell 2016, Pritchard 2016). We consider this variant to be pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Quest Diagnostics Nichols Institute San Juan Capistrano	Apr 19, 2023	This frameshift variant alters the translational reading frame of the RAD51D mRNA and causes the premature termination of RAD51D protein synthesis. The frequency of this variant in the general population, 0.000008 (2/251280 chromosomes, http://gnomad.broadinstitute.org), is consistent with pathogenicity. In the published literature, the variant has been reported in individuals with breast and/or ovarian cancer (PMID: 27153395 (2016)), prostate cancer (PMID: 27433846 (2016)), and colorectal cancer (PMID: 27433846 (2015)). Based on the available information, this variant is classified as pathogenic. -

Pathogenic, criteria provided, single submitter	clinical testing	Myriad Genetics, Inc.	Apr 06, 2023	This variant is considered pathogenic. This variant creates a frameshift predicted to result in premature protein truncation. -
Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Nov 14, 2023	This sequence change creates a premature translational stop signal (p.Gly110Argfs*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 (rs730882119, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with prostate cancer and breast and ovarian cancer (PMID: 27153395, 27433846). ClinVar contains an entry for this variant (Variation ID: 182849). For these reasons, this variant has been classified as Pathogenic. -

Hereditary cancer-predisposing syndrome

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Mar 03, 2022	The c.326dupC pathogenic mutation, located in coding exon 4 of the RAD51D gene, results from a duplication of C at nucleotide position 326, causing a translational frameshift with a predicted alternate stop codon (p.G110Rfs*2). 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. -
Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Apr 08, 2021	This variant inserts 1 nucleotide in exon 4 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 reported in individuals affected with colorectal cancer or prostate cancer (PMID: 26681312, 27433846). This variant has been identified in 2/251280 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. -
