Variant summary
Our verdict is Uncertain significance. Variant got 2 ACMG points: 4P and 2B. PM1PM2BP4_Moderate
The NM_000051.4(ATM):c.3088A>G(p.Lys1030Glu) variant causes a missense change. The variant allele was found at a frequency of 0.000000685 in 1,459,994 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 in silico tools predict 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. K1030R) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 07, 2019 | The p.K1030E variant (also known as c.3088A>G), located in coding exon 20 of the ATM gene, results from an A to G substitution at nucleotide position 3088. The lysine at codon 1030 is replaced by glutamic acid, an amino acid with similar properties. This amino acid position is not well 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Dec 11, 2019 | This missense variant replaces lysine with glutamic acid at codon 1030 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). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has been identified in 1/251222 chromosomes 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. - |
Ataxia-telangiectasia syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 18, 2023 | 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 216200). This variant has not been reported in the literature in individuals affected with ATM-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 1030 of the ATM protein (p.Lys1030Glu). - |
