Uncertain significance, no assertion criteria provided | clinical testing | Department of Pathology and Laboratory Medicine, Sinai Health System | - | The ATM p.Ser877Thr variant was identified in 3 of 5062 proband chromosomes (frequency: 0.0006) from individuals or families with breast cancer and was present in 3 of 4490 control chromosomes (frequency: 0.0007) from healthy individuals (Tavtigian 2009). The variant was also identified in the following databases: dbSNP (ID: rs370269552) as "With Uncertain significance allele", ClinVar (1x likely benign, 2x uncertain significance), and Clinvitae. The variant was not identified in COGR, Cosmic, MutDB, LOVD 3.0, or the ATM-LOVD database. The variant was identified in control databases in 9 of 246196 chromosomes (1 homozygous) at a frequency of 0.00004 (Genome Aggregation Database Feb 27, 2017). It was observed in the following populations: Other in 1 of 5484 chromosomes (freq: 0.0002), European in 1 of 111666 chromosomes (freq: 0.000009), East Asian in 4 of 17238 chromosomes (freq: 0.0002), and South Asian in 3 of 30780 chromosomes (freq: 0.0001). The variant was not observed in the African, Latino, Ashkenazi Jewish, or Finnish populations. The p.Ser877 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and 1 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) 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. - |

Hereditary cancer-predisposing syndrome Benign:2
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 30, 2018 | 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. - |

Uncertain significance, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jan 10, 2020 | Variant summary: ATM c.2630G>C (p.Ser877Thr) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.6e-05 in 251400 control chromosomes in the gnomAD database, including 1 homozygote. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.2630G>C has been reported in the literature in individuals affected with Breast Cancer and lung cancer as well as in controls (Bernstein_2010, Chan_2018, Lu_2015, Parry_2017, Tavtigian_2009). These reports do not provide unequivocal conclusions about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (3x benign/likely benign, 1x VUS). Based on the evidence outlined above, the variant was classified as uncertain significance. - |
