GeneDx RCV000479991 SCV000570502 uncertain significance not provided 2018-01-17 criteria provided, single submitter clinical testing This variant is denoted ATM c.2606C>G at the cDNA level, p.Ala869Gly (A869G) at the protein level, and results in the change of an Alanine to a Glycine (GCA>GGA). This variant was observed in at least one individual with pancreatic cancer and a family history of cancer (Chaffee 2017). ATM Ala869Gly was observed at an allele frequency of 0.0499% (12/24028) in individuals of African ancestry in large population cohorts (Lek 2016). This variant is not located in a known functional domain. In-silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether ATM Ala869Gly is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
Invitae RCV000476653 SCV000547002 uncertain significance Ataxia-telangiectasia syndrome 2018-10-29 criteria provided, single submitter clinical testing This sequence change replaces alanine with glycine at codon 869 of the ATM protein (p.Ala869Gly). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and glycine. This variant is present in population databases (rs145513717, ExAC 0.05%). This variant has not been reported in the literature in individuals with ATM-related disease. ClinVar contains an entry for this variant (Variation ID: 184982). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
