Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4
The NM_000051.4(ATM):c.1768G>C(p.Glu590Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00000657 in 152,192 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign 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. E590G) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
This missense variant replaces glutamic acid with glutamine at codon 590 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with ATM-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
The p.E590Q variant (also known as c.1768G>C), located in coding exon 10 of the ATM gene, results from a G to C substitution at nucleotide position 1768. The glutamic acid at codon 590 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Ataxia-telangiectasia syndrome Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 590 of the ATM protein (p.Glu590Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 524402). 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 not expected to disrupt ATM protein function with a negative predictive value of 95%. 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. -
