Ambry Genetics RCV002907353 SCV003674005 uncertain significance Inborn genetic diseases 2022-12-21 criteria provided, single submitter clinical testing The c.2879C>T (p.A960V) alteration is located in exon 21 (coding exon 21) of the ATP1A2 gene. This alteration results from a C to T substitution at nucleotide position 2879, causing the alanine (A) at amino acid position 960 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
Labcorp Genetics (formerly Invitae), Labcorp RCV003585365 SCV004265451 uncertain significance Familial hemiplegic migraine 2023-10-15 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 960 of the ATP1A2 protein (p.Ala960Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATP1A2-related conditions. ClinVar contains an entry for this variant (Variation ID: 2333070). 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 not expected to disrupt ATP1A2 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.
