Submissions by phenotype
Ataxia-telangiectasia syndrome Uncertain:2
This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 2431 of the ATM protein (p.Lys2431Glu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with breast cancer (PMID: 12935922). ClinVar contains an entry for this variant (Variation ID: 220522). 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.K2431E variant (also known as c.7291A>G), located in coding exon 48 of the ATM gene, results from an A to G substitution at nucleotide position 7291. The lysine at codon 2431 is replaced by glutamic acid, an amino acid with similar properties. This alteration has been detected in 1/4112 breast cancer patients and 0/2399 healthy control individuals across numerous studies (Tavtigian SV et al. Am. J. Hum. Genet. 2009 Oct;85:427-46). This amino acid position is not well 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. -
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Observed in individuals with a personal or family history including breast and other cancers (Sommer et al., 2003; Tavtigian et al., 2009; Tung et al., 2015; Decker et al., 2017); This variant is associated with the following publications: (PMID: 25186627, 28779002, 12935922, 19781682, 23532176) -
