RCV000489213 | SCV000577004 | uncertain significance | not provided | 2023-05-04 | criteria provided, single submitter | clinical testing | In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; In addition, In silico analysis suggests this variant may impact gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 26666653) |
Invitae | RCV000653325 | SCV000775204 | uncertain significance | Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 | 2023-09-15 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with CACNA1A-related conditions. This variant is present in population databases (rs749309558, gnomAD 0.006%). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 391 of the CACNA1A protein (p.Gly391Arg). ClinVar contains an entry for this variant (Variation ID: 426536). 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. 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. |
