Submissions by phenotype
Ataxia-telangiectasia syndrome Uncertain:2
This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 398 of the ATM protein (p.Asp398Asn). This variant is present in population databases (no rsID available, gnomAD 0.003%). 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: 230905). 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 p.D398N variant (also known as c.1192G>A), located in coding exon 8 of the ATM gene, results from a G to A substitution at nucleotide position 1192. The aspartic acid at codon 398 is replaced by asparagine, an amino acid with highly similar properties. Based on protein sequence alignment, this amino acid position is highly conserved through repotiles, but not in lower species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
This missense variant replaces aspartic acid with asparagine at codon 398 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 been identified in 1/251238 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. -
