Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PP2PP3
The NM_152296.5(ATP1A3):c.1654G>C(p.Glu552Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000373 in 1,606,876 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E552K) has been classified as Uncertain significance.

Dystonia 12 Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 552 of the ATP1A3 protein (p.Glu552Gln). This variant is not present in population databases (gnomAD no frequency). 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 573096). This variant has not been reported in the literature in individuals affected with ATP1A3-related conditions.
