Variant summary
Our verdict is Benign. The variant received -14 ACMG points: 0P and 14B. BP4_StrongBP6_Very_StrongBP7BS2_Supporting
The NM_000465.4(BARD1):c.2172G>T(p.Ala724Ala) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000533 in 1,614,080 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 Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. A724A) has been classified as Likely benign.

Hereditary cancer-predisposing syndrome Benign:3
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 Benign:2

This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
Malignant tumor of breast Uncertain:1
The BARD1 p.Ala724= variant was not identified in the literature. The variant was identified in dbSNP (ID: rs143331809) as "With Likely benign allele", and in ClinVar (classified as likely benign by Invitae, Ambry Genetics and Color). The variant was identified in control databases in 8 of 277090 chromosomes at a frequency of 0.00003 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the European population in 8 of 126586 chromosomes (freq: 0.00006); it was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The p.Ala724= 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 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
