| Invitae | RCV000541711 | SCV000645404 | pathogenic | Dystonia 12 | 2023-10-03 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 811 of the ATP1A3 protein (p.Ser811Pro). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with alternating hemiplegia of childhood (PMID: 22842232, 26297560, 26410222). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 37109). 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 ATP1A3 protein function. Experimental studies have shown that this missense change affects ATP1A3 function (PMID: 22842232). For these reasons, this variant has been classified as Pathogenic. |
