GeneDx RCV000159658 SCV000209654 uncertain significance not provided 2018-12-06 criteria provided, single submitter clinical testing This variant is denoted ATM c.8296G>A at the cDNA level, p.Val2766Ile (V2766I) at the protein level, and results in the change of a Valine to an Isoleucine (GTT>ATT). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. ATM Val2766Ile was not observed in large population cohorts (Lek 2016). ATM Val2766Ile is located in the kinase domain (Stracker 2013). 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 Val2766Ile is a pathogenic or benign variant. We consider it to be a variant of uncertain significance.
Invitae RCV000226399 SCV000283078 uncertain significance Ataxia-telangiectasia syndrome 2018-12-10 criteria provided, single submitter clinical testing This sequence change replaces valine with isoleucine at codon 2766 of the ATM protein (p.Val2766Ile). The valine residue is moderately conserved and there is a small physicochemical difference between valine and isoleucine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with ATM-related disease. ClinVar contains an entry for this variant (Variation ID: 181895). 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.
