The ATM p.Leu695= variant was identified in 2 of 5526 proband chromosomes (frequency: 0.00018) from individuals or families with breast cancer (Bernstein_2010, Rosenstein_2006). The variant was also identified in dbSNP (ID: rs786202229) as “With Likely benign allele”, ClinVar (as likely benign by Ambry Genetics, Invitae, and Color Genomics and as uncertain significance by Integrated Genetics), and Clinvitae (2x). The variant was not identified in the Cosmic, MutDB, LOVD 3.0, or ATM-LOVD databases. The variant was identified in control databases in 1 of 30948 chromosomes at a frequency of 0.000032 (Genome Aggregation Database Feb 27, 2017). It was observed in the “Other” population in 1 of 980 chromosomes (freq: 0.00102), but not in the African, Latino, European (Non-Finnish), Ashkenazi Jewish, East Asian, European (Finnish), and South Asian populations. The p.Leu695Leu 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, 3 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict the creation of a cryptic 3’ splice site; however, this information is not predictive enough to assume 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. -
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
