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.

Variant summary: The BARD1 c.722C>G (p.Ser241Cys) variant causes a missense change involving the alteration of a conserved nucleotide. 3/4 in silico tools predict a damaging outcome for this variant (SNPsandGO not captured due to low reliability index). The variant was found in the control population dataset of ExAC in 25/114604 control chromosomes, predominantly observed in the East Asian subpopulation at a frequency of 0.002784 (24/8622). This frequency is about 13 times the estimated maximal expected allele frequency of a pathogenic BARD1 variant (0.0002188), suggesting this is likely a benign polymorphism found primarily in the populations of East Asian origin. A case-control study found this variant to not be significantly associated with breast cancer (Ishitobi_BARD1_2003). This variant was found in a pancreatic ductal adenocarcinoma patient with no strong evidence for causality (Ohmoto_2016). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. Taken together, this variant is classified as benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -

The BARD1 p.Ser241Cys variant was identified in 11 of 286 proband chromosomes (frequency: 0.04) from individuals or families with breast cancer and was present in 8 of 310 control chromosomes (frequency: 0.03) from healthy individuals (Ishitobi 2003). The variant was also identified in the following databases: dbSNP (ID: rs3738885) as With Uncertain significance, other allele, ClinVar (classified as benign by GeneDx, Ambry Genetics, Invitae, Color Genomics; classified as likely benign by Counsyl, QDNISJC clinical laboratory), Clinvitae, MutDB, Zhejiang Colon Cancer Database (2X). The variant was not identified in Cosmic, database. The variant was identified in control databases in 27 of 211500 chromosomes at a frequency of 0.0001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: Other in 1 of 4468 chromosomes (freq: 0.0002), East Asian in 26 of 15562 chromosomes (freq: 0.002); it was not observed in the African, Latino, European, Ashkenazi Jewish, Finnish, and South Asian populations. Although the p.Ser241 residue is not conserved in mammals and other organisms, computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein. The variant occurs outside of the splicing consensus sequence and 4 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing. However, this information is not predictive enough to assume pathogenicity. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
