Labcorp Genetics (formerly Invitae), Labcorp RCV000548031 SCV000627624 uncertain significance Long QT syndrome 2017-01-21 criteria provided, single submitter clinical testing In summary, this variant is a rare missense change with uncertain impact on protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. 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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant is present in population databases (rs765190989, ExAC 0.006%) but has not been reported in the literature in individuals with an ANK2-related disease. This sequence change replaces histidine with tyrosine at codon 522 of the ANK2 protein (p.His522Tyr). The histidine residue is moderately conserved and there is a moderate physicochemical difference between histidine and tyrosine.
