Ambry Genetics RCV000619782 SCV000738086 likely benign Cardiovascular phenotype 2018-11-16 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
Invitae RCV000631659 SCV000752742 uncertain significance Long QT syndrome 2023-10-23 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 2796 of the ANK2 protein (p.Pro2796Leu). This variant is present in population databases (rs182956726, gnomAD 0.009%). This variant has not been reported in the literature in individuals affected with ANK2-related conditions. ClinVar contains an entry for this variant (Variation ID: 519475). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
GeneDx RCV001591384 SCV001822733 uncertain significance not provided 2020-01-03 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar with conflicting interpretations of pathogenicity (ClinVar Variant ID# 519475; Landrum et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function
