Labcorp Genetics (formerly Invitae), Labcorp	RCV003790936	SCV004582877	uncertain significance	Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42	2023-02-03	criteria provided, single submitter	clinical testing	This variant has not been reported in the literature in individuals affected with CACNA1A-related conditions. 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. 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 CACNA1A protein function. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 2096 of the CACNA1A protein (p.Arg2096His).
