Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 2P and 6B. PM2BP4_StrongBP6BP7
The NM_000051.4(ATM):c.750A>G(p.Arg250=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R250R) has been classified as Uncertain significance.

Ataxia-telangiectasia syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 22, 2017 | Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a ATM-related disease. This sequence change affects codon 250 of the ATM mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ATM protein. In summary, this is a novel silent change with uncertain impact on splicing. It has been classified as a Variant of Uncertain Significance. - |
Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 19, 2015 | 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:1
Benign, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Apr 23, 2024 | This variant is considered benign. This variant is a silent/synonymous amino acid change and it is not expected to impact splicing. - |
