GeneDx RCV000586113 SCV000149171 uncertain significance not provided 2018-11-07 criteria provided, single submitter clinical testing This variant is denoted ATM c.8156G>A at the cDNA level, p.Arg2719His (R2719H) at the protein level, and results in the change of an Arginine to a Histidine (CGT>CAT). This variant has been reported in individuals with suspected hereditary breast/ovarian cancer as well as in an individual with urothelial bladder cancer (Brunet 2008, Balb?s-Mart?nez 2013, Maxwell 2016, Mucaki 2016). ATM Arg2719His was observed at an allele frequency of 0.051%, (17/33,528) in individuals of Latino ancestry in large population cohorts (Lek 2016). ATM Arg2719His is located in the ATP binding domain within the kinase domain (Lavin 2004, Stracker 2013). In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, it is unclear whether ATM Arg2719His is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.

Invitae RCV000232453 SCV000283074 uncertain significance Ataxia-telangiectasia syndrome 2019-01-11 criteria provided, single submitter clinical testing This sequence change replaces arginine with histidine at codon 2719 of the ATM protein (p.Arg2719His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs55982963, ExAC 0.1%). This variant has been observed in individuals affected with breast cancer (PMID: 18384426, 19781682, 21445571). ClinVar contains an entry for this variant (Variation ID: 127456). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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.

Integrated Genetics/Laboratory Corporation of America RCV000586113 SCV000694372 uncertain significance not provided 2017-02-16 criteria provided, single submitter clinical testing Variant summary: The c.8156G>A (p.Arg2719His) in ATM gene is a missense change that involves a conserved nucleotide and 4/5 in silico tools predict deleterious outcome. The variant is located in the PI3/PI4-kinase domain, however no functional studies confirming deleterious effect of this change have been reported at the time of evaluation. The variant is present in the control population dataset of ExAC at a frequency of 0.00017 (20/116502 chrs tested), predominantly in individuals of Latino descent (0.0017; 13/1130chrs tested), including 1 homozygote. The latter frequency exceeds the maximum expected allele frequency for a pathogenic variant of 0.0010, suggesting it is may be an ethnic-specific functional polymorphism. The variant has been reported in BrC pts without strong evidence for causality. The variant is cited as VUS by a reputable databases/clinical laboratories without evidence to independently evaluate. Taking together, the variant was classified as VUS.
