Submissions by phenotype
Hereditary cancer-predisposing syndrome Benign:4
- -
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. -
The synonymous variant NM_000051.4(ATM):c.2679A>G (p.Gln893=) has been reported to ClinVar as Benign/Likely benign with a status of (2 stars) criteria provided, multiple submitters, no conflicts (Variation ID 184455 as of 2025-01-02). The p.Gln893= variant is not predicted to disrupt an existing splice site. The p.Gln893= variant is predicted to introduce a novel splice site by 1 of 4 splice site algorithms. The p.Gln893= variant results in a substitution of a base that is not predicted conserved by GERP++ and PhyloP. For these reasons, this variant has been classified as Likely Benign. -
BP4, BP7 c.2679A>G, located in exon 18 of the ATM gene, is predicted to result in no amino acid change, p.(Gln893=) (BP7).This variant is found in 3/268196 alleles at a frequency of 0.0011% in the gnomAD v2.1.1 database, non-cancer dataset.The SpliceAI algorithm predicts no significant impact on splicing (BP4). To our knowledge, neither relevant clinical data nor well-stablished functional studies have been reported for this variant. This variant has been reported in the ClinVar database (1x benign, 8x likely benign) but it is not reported in the LOVD database. Based on currently available information, the variant c.2679A>G should be considered a likely benign variant. -
not specified Benign:3
- -
- -
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:1
- -
not provided Benign:1
- -
ATM-related disorder Benign:1
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
Familial colorectal cancer type X Benign:1
- -
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. -
