Ataxia-telangiectasia syndrome Uncertain:2
- -
This sequence change replaces asparagine, which is neutral and polar, with threonine, which is neutral and polar, at codon 2412 of the ATM protein (p.Asn2412Thr). 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: 407621). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ATM protein function. 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.N2412T variant (also known as c.7235A>C), located in coding exon 48 of the ATM gene, results from an A to C substitution at nucleotide position 7235. The asparagine at codon 2412 is replaced by threonine, an amino acid with 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. -
ATM-related disorder Uncertain:1
The ATM c.7235A>C variant is predicted to result in the amino acid substitution p.Asn2412Thr. This variant has been reported in an individual with breast cancer (Patient 18, Nunziato et al. 2019. PubMed ID: 30482293). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. It is interpreted as uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/407621/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
