Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM1BP4_Moderate
The NM_000051.4(ATM):āc.8129A>Gā(p.Lys2710Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000496 in 1,614,006 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K2710E) has been classified as Uncertain significance.

Submissions by phenotype
not provided Uncertain:2Other:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in an individual with colorectal cancer (Pearlman et al., 2017); This variant is associated with the following publications: (PMID: 28492532, 29596542, 27978560) -
Variant interpreted as Uncertain significance and reported on 02-12-2020 by Lab or GTR ID 26957. GenomeConnect assertions are reported exactly as they appear on the patient-provided report from the testing laboratory. GenomeConnect staff make no attempt to reinterpret the clinical significance of the variant. -

Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
This missense variant replaces lysine with arginine at codon 2710 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function. 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 been identified in 1/251382 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. -
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. -
Ataxia-telangiectasia syndrome Uncertain:1
This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 2710 of the ATM protein (p.Lys2710Arg). This variant is present in population databases (rs587782001, gnomAD 0.007%). This missense change has been observed in individual(s) with colorectal cancer (PMID: 27978560). ClinVar contains an entry for this variant (Variation ID: 141775). 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. -
