Submissions by phenotype
Ataxia-telangiectasia syndrome Uncertain:2
This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 1490 of the ATM protein (p.Ser1490Gly). This variant is present in population databases (no rsID available, gnomAD 0.003%). This missense change has been observed in individual(s) with melanoma and/or renal clear cell carcinoma (PMID: 26689913, 34262154). ClinVar contains an entry for this variant (Variation ID: 230691). 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.S1490G variant (also known as c.4468A>G), located in coding exon 29 of the ATM gene, results from an A to G substitution at nucleotide position 4468. The serine at codon 1490 is replaced by glycine, an amino acid with similar properties. This alteration has been reported in a renal clear cell carcinoma patient from a cohort of 4034 cancer cases from The Cancer Genome Atlas (Lu C et al. Nat Commun, 2015 Dec;6:10086). This amino acid position is 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. -
This missense variant replaces serine with glycine at codon 1490 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 been reported in an individual affected with renal clear cell carcinoma (PMID: 26689913). This variant has been identified in 2/251292 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. -

ATM-related disorder Uncertain:1
The ATM c.4468A>G variant is predicted to result in the amino acid substitution p.Ser1490Gly. This variant has been reported in an individual with kidney renal clear cell carcinoma (Table S12, Lu et al. 2015. PubMed ID: 26689913). This variant is reported in 2 of ~251,000 alleles in gnomAD (http://gnomad.broadinstitute.org/variant/11-108163377-A-G). It is interpreted as uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/230691/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 29684080, 26689913, 34262154) -
Familial cancer of breast Benign:1
This variant is considered likely benign. This variant is strongly associated with less severe personal and family histories of cancer, typical for individuals without pathogenic variants in this gene [PMID: 25085752]. -
