Ataxia-telangiectasia syndrome Uncertain:2
- -
This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 3043 of the ATM protein (p.Lys3043Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with biliary tract cancer (PMID: 36243179). ClinVar contains an entry for this variant (Variation ID: 246403). 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
This missense variant replaces lysine with arginine at codon 3043 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 hereditary cancer in the literature. This variant has not been identified 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. -
The p.K3043R variant (also known as c.9128A>G), located in coding exon 62 of the ATM gene, results from an A to G substitution at nucleotide position 9128. The lysine at codon 3043 is replaced by arginine, an amino acid with highly similar properties. This variant was observed in an individual with early onset-breast cancer amongst a cohort of 1781 non-Ashkenazi Jewish individuals undergoing BRCA1/2 gene testing based on a personal history of breast cancer (Tung N et al. Cancer, 2015 Jan;121:25-33). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
