Labcorp Genetics (formerly Invitae), Labcorp RCV003783732 SCV004571413 pathogenic Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 2023-10-16 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 1695 of the CACNA1A protein (p.Val1695Phe). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with CACNA1A-related conditions (PMID: 18498393). In at least one individual the variant was observed to be de novo. 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 expected to disrupt CACNA1A protein function. For these reasons, this variant has been classified as Pathogenic.
