The missense variant p.G706R in ATP1A3 (NM_152296.5) has been previously reported as a de novo mutation in patient with alternating hemiplegia of childhood (Yang et al, 2014). It has been submitted to the ClinVar database as Pathogenic. The p.G706R variant is novel (not in any individuals) in gnomAD Exomes and is novel (not in any individuals) in 1000 Genomes. The p.G706R missense variant is predicted to be damaging by both SIFT and PolyPhen2. The glycine residue at codon 706 of ATP1A3 is conserved in all mammalian species. The nucleotide c.2116 in ATP1A3 is predicted to be conserved by GERP++ and PhyloP across 100 vertebrates. Hence the above variant is classified as Likely Pathogenic as currently variant is being evaluated by proband solo exome.
