Athena Diagnostics Inc	RCV000517519	SCV000612509	pathogenic	not provided	2023-03-30	criteria provided, single submitter	clinical testing	The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant has been identified in individuals with familial hemiplegic migraine (FHM) and/or cerebellar ataxia (PMID: 24498617, 17142831, 11439943, 12707077). This variant segregates with disease in multiple families. Assessment of experimental evidence suggests this variant results in abnormal protein function. This variant leads to altered calcium channel function (PMID: 10734061).

Invitae	RCV001380080	SCV001578023	pathogenic	Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42	2022-08-12	criteria provided, single submitter	clinical testing	ClinVar contains an entry for this variant (Variation ID: 8505). For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects CACNA1A function (PMID: 10734061). 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. This missense change has been observed in individuals with CACNA1A-related conditions (PMID: 12707077, 20837964, 24498617, 26814174). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs121908217, gnomAD 0.0009%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 583 of the CACNA1A protein (p.Arg583Gln).
