Labcorp Genetics (formerly Invitae), Labcorp RCV005070382 SCV005702268 uncertain significance not provided 2024-04-15 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 614 of the CACNA1E protein (p.Ile614Val). This variant is present in population databases (rs373361032, gnomAD 0.007%). This missense change has been observed in individual(s) with late onset episodic ataxia (PMID: 32466254). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CACNA1E 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.
