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. -
Ataxia-telangiectasia syndrome Benign:2
The ATM p.Gly2694= variant was identified in 1 of 26174 proband chromosomes (frequency: 3.8E-05) from individuals or families with breast cancer and was was present in 2 of 10976 control chromosomes (frequency: 0.0002) from healthy individuals (Decker 2017). The variant was also identified in dbSNP (ID: rs540266635) as "with Likely benign allele" and in ClinVar (3x as likely benign by GeneDx, Invitae and one other submitter). It was not identified in the LOVD 3.0 database. The variant was identified in control databases in 29 of 246042 chromosomes at a frequency of 0.0001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 1 of 5478 chromosomes (freq: 0.0002), and South Asian in 28 of 30782 chromosomes (freq: 0.0009), while the variant was not observed in the African, Latino, European, Ashkenazi Jewish, East Asian or Finnish populations. The p.Gly2694= 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. -
- -
not specified Benign:1
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. -
Familial cancer of breast Benign:1
This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. -
