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.

Department of Pathology and Laboratory Medicine, Sinai Health System
Significance: Likely benign
Review Status: no assertion criteria provided
Collection Method: clinical testing

The BARD1 p.Gly505= variant was not identified in the literature. The variant was identified dbSNP (rs139721211) as “with likely benign allele” and ClinVar (interpreted as "likely benign" by Invitae and 2 others, "benign" by GeneDx and "uncertain significance" by Integrated Genetics). The variant was identified in control databases in 25 of 277,034 chromosomes at a frequency of 0.00009 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 20 of 24,030 chromosomes (freq: 0.0008), Other in 1 of 6452 chromosomes (freq: 0.0002), Latino in 4 of 34,390 chromosomes (freq: 0.0001); it was not observed in the European, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The p.Gly505= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. 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. -
