Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4_ModerateBP6BP7BS2_Supporting
The NM_000465.4(BARD1):c.2280G>A(p.Ser760Ser) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000018 in 1,614,008 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Hereditary cancer-predisposing syndrome Benign:4
- -
- -
- -
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. -
Familial cancer of breast Uncertain:1Benign:2
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
- -
not specified Benign:2
- -
This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
not provided Benign:1

Malignant tumor of breast Benign:1
The BARD1 p.Ser760= variant was not identified in the literature. The variant was identified in dbSNP (ID: rs749959440) as "with other allele" and in ClinVar (classified as likely benign by Ambry Genetics, Invitae and two other submitters and as benign by GeneDx) database. It was also identified in control databases in 6 of 246004 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Latino in 1 of 33566 chromosomes (freq: 0.00003), European in 3 of 111490 chromosomes (freq: 0.00003), East Asian in 1 of 17246 chromosomes (freq: 0.00006), and South Asian in 1 of 30778 chromosomes (freq: 0.00003), while the variant was not observed in the African, Other, Ashkenazi Jewish or Finnish populations. The p.Ser760= 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. In addition, 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. -
