Labcorp Genetics (formerly Invitae), Labcorp RCV001359935 SCV001555824 uncertain significance Long QT syndrome 2022-07-19 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 1051844). 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. 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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with ANK2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 566 of the ANK2 protein (p.Pro566Ser).
Ambry Genetics RCV002413848 SCV002715431 uncertain significance Cardiovascular phenotype 2023-10-19 criteria provided, single submitter clinical testing The p.P566S variant (also known as c.1696C>T), located in coding exon 16 of the ANK2 gene, results from a C to T substitution at nucleotide position 1696. The proline at codon 566 is replaced by serine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
