The ATM p.Leu651= variant was identified in 14 of 14208 proband chromosomes (frequency: 0.001) from Japanese individuals or families with breast cancer and was present in 43 of 47462 control chromosomes (frequency: 0.0009) from healthy individuals (Momozawa 2018). The variant was also identified in dbSNP (ID: rs730881283) “With Uncertain significance allele”, ClinVar (classified as benign by GeneDx; as likely benign by Ambry Genetics, Invitae, Color, and Prevention Genetics; and as uncertain significance by Integrated Genetics/Laboratory Corporation of America), and LOVD 3.0 (1x as benign). The variant was identified in control databases in 22 of 277048 chromosomes at a frequency of 0.00008 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 24030 chromosomes (freq: 0.00004), Other in 1 of 6460 chromosomes (freq: 0.0002), Latino in 14 of 34416 chromosomes (freq: 0.0004), European Non-Finnish in 5 of 126592 chromosomes (freq: 0.00004), and South Asian in 1 of 30778 chromosomes (freq: 0.00003), while not observed in the Ashkenazi Jewish, East Asian, or European Finnish populations. The p.Leu651= 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. -
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. -
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. -
Ataxia-telangiectasia syndrome Benign:2
- -
- -
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. -
