Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 0P and 1B. BP4
The NM_000051.4(ATM):c.5892G>C(p.Lys1964Asn) variant causes a missense change. The variant allele was found at a frequency of 0.0000112 in 1,613,278 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. K1964E) has been classified as Likely benign.

Variant interpretted as Uncertain significance and reported on 03/23/2018 by GTR ID Credit Valley Hospital Department of Laboratory Medicine. 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. -
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 breast cancer (Abdel-Razeq et al., 2022); This variant is associated with the following publications: (PMID: 35402282, 23532176) -
Ataxia-telangiectasia syndrome Uncertain:2
This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 1964 of the ATM protein (p.Lys1964Asn). This variant is present in population databases (rs786202728, gnomAD 0.0009%). 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: 186146). 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. -

Hereditary cancer-predisposing syndrome Uncertain:2
The c.5892G>C (p.K1964N) alteration is located in exon 39 (coding exon 38) of the ATM gene. This alteration results from a G to C substitution at nucleotide position 5892, causing the lysine (K) at amino acid position 1964 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
This missense variant replaces lysine with asparagine at codon 1964 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 been reported in an individual affected with breast cancer (PMID: 35402282). This variant has been identified in 1/250968 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. -
