Invitae RCV000474729 SCV000546741 uncertain significance Ataxia-telangiectasia syndrome 2018-06-19 criteria provided, single submitter clinical testing This sequence change replaces lysine with asparagine at codon 659 of the ATM protein (p.Lys659Asn). The lysine residue is weakly conserved and there is a moderate physicochemical difference between lysine and asparagine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with an ATM-related disease. ClinVar contains an entry for this variant (Variation ID: 407501). 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, this variant has uncertain impact on ATM function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
