Ataxia-telangiectasia syndrome Uncertain:1
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: 524228). This variant has not been reported in the literature in individuals affected with ATM-related conditions. This variant is present in population databases (rs767939328, gnomAD 0.002%). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2043 of the ATM protein (p.Gly2043Ser). -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.G2043S variant (also known as c.6127G>A), located in coding exon 41 of the ATM gene, results from a G to A substitution at nucleotide position 6127. The glycine at codon 2043 is replaced by serine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate 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. -
