Invitae RCV000055992 SCV001576579 likely pathogenic Dystonia 12 2020-08-14 criteria provided, single submitter clinical testing This sequence change replaces serine with phenylalanine at codon 684 of the ATP1A3 protein (p.Ser684Phe). The serine residue is highly conserved and there is a large physicochemical difference between serine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with rapid-onset dystonia-parkinsonism (PMID: 19936820, 24523486, Invitae). ClinVar contains an entry for this variant (Variation ID: 65759). 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. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
