Genes affected

BARD1 (HGNC:952): (BRCA1 associated RING domain 1) This gene encodes a protein which interacts with the N-terminal region of BRCA1. In addition to its ability to bind BRCA1 in vivo and in vitro, it shares homology with the 2 most conserved regions of BRCA1: the N-terminal RING motif and the C-terminal BRCT domain. The RING motif is a cysteine-rich sequence found in a variety of proteins that regulate cell growth, including the products of tumor suppressor genes and dominant protooncogenes. This protein also contains 3 tandem ankyrin repeats. The BARD1/BRCA1 interaction is disrupted by tumorigenic amino acid substitutions in BRCA1, implying that the formation of a stable complex between these proteins may be an essential aspect of BRCA1 tumor suppression. This protein may be the target of oncogenic mutations in breast or ovarian cancer. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Hereditary cancer-predisposing syndrome

Pathogenic:3

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Nov 01, 2021	The p.Q564* pathogenic mutation (also known as c.1690C>T), located in coding exon 8 of the BARD1 gene, results from a C to T substitution at nucleotide position 1690. This changes the amino acid from a glutamine to a stop codon within coding exon 8. This alteration has been reported in numerous patients diagnosed with breast and/or ovarian cancer (Ratajska M et al. Breast Cancer Res. Treat. 2012 Jan;131:89-97; Cybulski C et al. Clin. Genet. 2015 Oct;88:366-70; Klonowska K et al. Sci. Rep. 2015 May;5:10424; Ramus SJ et al. J Natl Cancer Inst. 2015 Nov;107:; Weber-Lassalle N et al. Breast Cancer Res. 2019 04;21:55; Shahi RB et al. BMC Cancer. 2019 Apr;19:313). Additionally, this alteration has been identified in a patient with triple-negative breast cancer (De Brakeleer S et al. Clin. Genet. 2016 Mar;89(3):336-40) and a male breast cancer patient (Pritzlaff M et al. Breast Cancer Res. Treat. 2017 Feb;161:575-586). 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. -

Pathogenic, criteria provided, single submitter	clinical testing	Color Diagnostics, LLC DBA Color Health	Nov 06, 2023	This variant changes 1 nucleotide in exon 8 of the BARD1 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 over 15 individuals affected with breast or ovarian cancer (PMID: 25994375, 26010302, 26315354, 26329992, 26681312, 28008555, 29625052, 30947698, 31036035, 32679805, 37239058, 37563628) and one individual affected with endometrial cancer (PMID: 27443514). In a large breast cancer case-control meta analysis, this variant has been observed in 17/60449 cases and 6/53455 controls (PMID: 33471991; Leiden Open Variation Database DB-ID BARD1_000187). This variant has been identified in 7/282686 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Loss of BARD1 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. -

The BARD1 c.1690C>T variant is predicted to result in premature protein termination (p.Gln564*). This variant has been reported in many individuals with breast and/or ovarian cancer (Ratajska et al 2012. PubMed ID: 21344236; Yurgelun MB et al 2015. PubMed ID: 25980754; Klonowska K et al 2015.

PubMed ID: 31036035; Tsaousis GN et al 2019. PubMed ID: 31159747). This variant is reported in 0.0054% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/2-215610566-G-A) and is interpreted as pathogenic (15) and uncertain significance (1) in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/127720/). Nonsense variants in BARD1 are expected to be pathogenic. This variant is interpreted as pathogenic. -

Variant summary: BARD1 c.1690C>T (p.Gln564X) 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. 5/5 computational tools predict no significant impact on normal splicing. However, Ratajska_2015 report that this variant may have an impact on splicing alteration. The variant allele was found at a frequency of 2.4e-05 in 252390 control chromosomes (gnomAD). c.1690C>T has been reported in the literature in multiple individuals affected with breast and/or ovarian cancer patients (e.g. Cybulski_2014, Weber-Lassalle_2019). These data indicate that the variant is very likely to be associated with disease. Nine other ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
