Labcorp Genetics (formerly Invitae), Labcorp RCV000795415 SCV000934878 uncertain significance Episodic ataxia type 1 2023-05-15 criteria provided, single submitter clinical testing This variant is present in population databases (no rsID available, gnomAD 0.003%). This sequence change replaces aspartic acid, which is acidic and polar, with glutamic acid, which is acidic and polar, at codon 10 of the KCNA1 protein (p.Asp10Glu). This variant has not been reported in the literature in individuals affected with KCNA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 642028). 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) performed at Invitae indicates that this missense variant is not expected to disrupt KCNA1 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.
