Invitae RCV001214065 SCV001385728 uncertain significance Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2020-08-25 criteria provided, single submitter clinical testing This sequence change replaces valine with leucine at codon 1563 of the CACNA1A protein (p.Val1563Leu). The valine residue is highly conserved and there is a small physicochemical difference between valine and leucine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with CACNA1A-related conditions. 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 disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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 RCV002511056 SCV002820649 uncertain significance not provided 2022-07-15 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
