Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000779698 SCV000916451 uncertain significance not specified 2018-06-11 criteria provided, single submitter clinical testing Variant summary: ANK2 c.6973G>C (p.Asp2325His) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2.2e-05 in 276420 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.6973G>C in individuals affected with Arrhythmia and no experimental evidence demonstrating its impact on protein function have been reported. A ClinVar submission from a clinical diagnostic laboratory cites the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.
Invitae RCV000806581 SCV000946586 uncertain significance Long QT syndrome 2018-09-20 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with histidine at codon 2325 of the ANK2 protein (p.Asp2325His). The aspartic acid residue is weakly conserved and there is a moderate physicochemical difference between aspartic acid and histidine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with ANK2-related disease. ClinVar contains an entry for this variant (Variation ID: 518570). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; 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.
