Invitae | RCV001856860 | SCV002273836 | pathogenic | Episodic ataxia type 2; Developmental and epileptic encephalopathy, 42 | 2023-05-20 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 422063). For these reasons, this variant has been classified as Pathogenic. 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 individual(s) with clinical features of CACNA1A-related conditions (Invitae). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 1644 of the CACNA1A protein (p.Asp1644Asn). |

RCV001264726 | SCV002767527 | likely pathogenic | Developmental and epileptic encephalopathy, 42 | 2020-05-21 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v0.6.1, this variant is classified as LIKELY PATHOGENIC. Following criteria are met: 0103 - Both loss and gain of function are known mechanism of disease for this gene. 0107 - This gene is known to be associated with autosomal dominant disease. 0200 - Variant is predicted to result in a missense amino acid change from aspartic acid to asparagine (exon 31). 0301 - Variant is absent from gnomAD. 0501 - Missense variant consistently predicted to be damaging by in silico tools or highly conserved with a major amino acid change. 0600 - Variant is located in an annotated domain or motif that does not have a well established function (extracellular region of Ion-trans domain; PDB, NCBI, DECIPHER). 0603 - Missense variant in a region that is highly intolerant to missense variation (constraint). 0705 - No comparable variants in relevant codon/region have previous evidence for pathogenicity. 0807 - Variant has not previously been reported in a clinical context (1X VUS in ClinVar). 0905 - No published segregation evidence has been identified for this variant. 1007 - No published functional evidence has been identified for this variant. 1204 - De novo variant (parental status not tested but assumed) Legend: (P) - Pathogenic, (N) - Neutral, (B) - Benign |
