Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_000465.4(BARD1):​c.253G>T​(p.Val85Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000502 in 1,610,076 control chromosomes in the GnomAD database, including 8 homozygotes. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V85A) has been classified as Uncertain significance.

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.

Review Status:criteria provided, single submitter

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

This variant is considered likely benign. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. -

Significance:Likely benign
Review Status:no assertion criteria provided
Collection Method:clinical testing

The BARD1 p.Val85Leu variant was identified in 2 of 482 proband chromosomes (frequency: 0.004) from individuals or families with breast cancer and was present in 2 of 450 control chromosomes (frequency: 0.004) from healthy individuals (De Brakeleer 2010, Jalkh 2017). The variant was also identified in the following databases: dbSNP (ID: rs370359540) as With Uncertain significance allele, ClinVar (classified as uncertain significance by Ambry Genetics, GeneDx; classified as benign by Invitae), Clinvitae (classified as uncertain significance by ClinVar), and the Zhejiang Colon Cancer Database. The variant was not identified in Cosmic, or MutDB databases. The variant was identified in control databases in 256 (3 homozygous) of 275536 chromosomes at a frequency of 0.001 in the following populations: South Asian in 247 of 30554 chromosomes (freq. 0.008), European Non-Finnish in 5 of 126084 chromosomes (freq. 0.00004), African in 2 of 23898 chromosomes (freq. 0.0001), East Asian in 1 of 18764 chromosomes (freq. 0.0001), Other in 1 of 6380 chromosomes (freq. 0.0001), increasing the likelihood this could be a low frequency benign variant in certain populations of origin (Genome Aggregation Consortium Feb 27, 2017). The p.Val85 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and 2 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. The variant was identified with a co-occurring pathogenic BRCA1 variant (c.C4327T p.R1443X), increasing the likelihood that the p.Val85Leu variant does not have clinical significance (Jalkh 2017). 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. -
