Variant summary
Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM1PM2PP3_Moderate
The NM_000051.4(ATM):c.7189C>G(p.Gln2397Glu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000274 in 1,461,752 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. Q2397R) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:3

The p.Q2397E variant (also known as c.7189C>G), located in coding exon 48 of the ATM gene, results from a C to G substitution at nucleotide position 7189. The glutamine at codon 2397 is replaced by glutamic acid, an amino acid with highly similar properties. This variant was reported in 1/60,466 breast cancer cases and in 0/53,461 controls (Dorling et al. N Engl J Med, 2021 02;384:428-439). 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. -
Ataxia-telangiectasia syndrome Uncertain:2

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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 490690). This missense change has been observed in individual(s) with prostate cancer (PMID: 32853339). This variant is present in population databases (rs747372355, gnomAD 0.003%). This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 2397 of the ATM protein (p.Gln2397Glu). -
