Variant summary
Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM5PP3_Strong
The NM_000051.4(ATM):c.8737G>C(p.Asp2913His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,830 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D2913Y) has been classified as Pathogenic.

Submissions by phenotype
not provided Uncertain:2
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 33436325, 28652578, 23532176) -

Ataxia-telangiectasia syndrome Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 2913 of the ATM protein (p.Asp2913His). This variant is present in population databases (rs756899044, gnomAD 0.0009%). This missense change has been observed in individual(s) with prostate cancer (PMID: 33436325). ClinVar contains an entry for this variant (Variation ID: 231464). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt ATM protein function with a positive predictive value of 95%. This variant disrupts the p.Asp2913 amino acid residue in ATM. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 21665257, 22071889). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.D2913H variant (also known as c.8737G>C), located in coding exon 59 of the ATM gene, results from a G to C substitution at nucleotide position 8737. The aspartic acid at codon 2913 is replaced by histidine, an amino acid with similar properties. A different alteration at this position, p.D2913Y, has been reported in multiple individuals with a clinical diagnosis of ataxia-telangiectasia in both homozygous and compound heterozygous states (Micol R et al. J. Allergy Clin. Immunol. 2011 Aug;128:382-9). Cell lines from an individual with ataxia telangiectasia who was heterozygous for p.D2913Y along with a second alteration in ATM, exhibited decreased response to ionizing radiation, decreased ATM protein expression, and abnormal cellular localization (Jacquemin V et al. Eur. J. Hum. Genet. 2012 Mar;20:305-12). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
