RCV002047201 | SCV002110977 | uncertain significance | Familial hemiplegic migraine | 2021-05-06 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine with methionine at codon 838 of the ATP1A2 protein (p.Thr838Met). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and methionine. 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. 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. This variant has not been reported in the literature in individuals with ATP1A2-related conditions. This variant is not present in population databases (ExAC no frequency). |
