Breast-ovarian cancer, familial, susceptibility to, 4 Pathogenic:6
This sequence change creates a premature translational stop signal (p.Gln151*) 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 (rs587781756, gnomAD 0.0009%). This premature translational stop signal has been observed in individual(s) with ovarian cancer (PMID: 26720728, 28591191). This variant is also known as c.511C>T and p.Q171*. ClinVar contains an entry for this variant (Variation ID: 141452). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
- -
This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. -

The RAD51D c.451C>T (p.Gln151*) variant causes the premature termination of RAD51D protein synthesis. This variant has been reported in the published literature in individuals with ovarian cancer (PMID: 26720728 (2016)), breast cancer (PMID: 28724667 (2017), 30111881 (2018), 30165555 (2018), 31300551 (2020)), and lung cancer (PMID: 35273153 (2022)). In a large breast cancer association study, this variant was reported in individuals with breast cancer as well as a healthy individual (PMID: 33471991 (2021), https://databases.lovd.nl/shared/variants/RAD51D). The frequency of this variant in the general population, 0.000004 (1/251464 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is consistent with pathogenicity. Based on the available information, this variant is classified as pathogenic. -

This pathogenic variant is denoted RAD51D c.451C>T at the cDNA level and p.Gln151Ter (Q151X) at the protein level. The substitution creates a nonsense variant, which changes a Glutamine to a premature stop codon (CAG>TAG), and is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. This variant has been reported in individuals with breast or ovarian cancer and is considered pathogenic (Norquist 2015, Sun 2017). -
Hereditary cancer-predisposing syndrome Pathogenic:2
This variant changes 1 nucleotide in exon 5 of the RAD51D gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with ovarian cancer (PMID: 26720728). This variant has been identified in 1/251464 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. -
The p.Q151* pathogenic mutation (also known as c.451C>T), located in coding exon 5 of the RAD51D gene, results from a C to T substitution at nucleotide position 451. This changes the amino acid from a glutamine to a stop codon within coding exon 5. This mutation has been reported in an individual diagnosed with breast cancer who also had a family history of breast and ovarian cancer (Konstanta I et al. J. Hum. Genet. 2018 Nov;63(11):1149-1158). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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. -

Hereditary breast ovarian cancer syndrome Pathogenic:1
Variant summary: RAD51D c.451C>T (p.Gln151X), also referred to as c.511C>T (p.Gln171X), 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. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 4e-06 in 251464 control chromosomes (gnomAD). c.451C>T has been reported in the literature in multiple individuals a personal and/or family history of breast and/or ovarian cancer (e.g. Norquist_2016, Stafford_2017, Sun_2017, Konstanta_2018, Mittal_2022). These data indicate that the variant is very likely to be associated with Hereditary Breast And Ovarian Cancer Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Nine submitters have provided clinical-significance assessments for this variant to ClinVar after 2014 and all classified the variant as pathogenic (n=8) or likely pathogenic (n=1). Based on the evidence outlined above, the variant was classified as pathogenic. -
