Submissions by phenotype
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.Arg751= variant was not identified in the literature. The variant was identified in dbSNP (ID: rs750001065) 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 10 of 246012 chromosomes at a frequency of 0.00004 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the European population in 10 of 111500 chromosomes (freq: 0.00009); it was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. The p.Arg751= 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. However, 2 of 4 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. -
