Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM2 PM5 PP2 PP3_Strong PP5_Moderate

The NM_152296.5(ATP1A3):​c.2051C>T​(p.Ser684Phe) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S684Y) has been classified as Likely pathogenic.

Genes affected

ATP1A3 (HGNC:801): (ATPase Na+/K+ transporting subunit alpha 3) The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of Na+/K+ -ATPases. Na+/K+ -ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The catalytic subunit of Na+/K+ -ATPase is encoded by multiple genes. This gene encodes an alpha 3 subunit. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr19-41976459-G-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 2124880.Status of the report is criteria_provided_single_submitter, 1 stars.
• PP2: Missense variant in the ATP1A3 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 110 curated pathogenic missense variants (we use a threshold of 10). The gene has 22 curated benign missense variants. Gene score misZ: 6.3327 (above the threshold of 3.09). Trascript score misZ: 9.1232 (above the threshold of 3.09). GenCC associations: The gene is linked to alternating hemiplegia of childhood 2, developmental and epileptic encephalopathy 99, ATP1A3-associated neurological disorder, cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss syndrome, dystonia 12, alternating hemiplegia of childhood, encephalopathy, acute, infection-induced, complex neurodevelopmental disorder.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.973
• PP5: Variant 19-41976459-G-A is Pathogenic according to our data. Variant chr19-41976459-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 65759.Status of the report is criteria_provided_single_submitter, 1 stars.
