Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PM2PP2PP3_StrongPP5_Moderate

The NM_152296.5(ATP1A3):c.2600G>A(p.Gly867Asp) 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. 13/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G867V) has been classified as Uncertain significance.

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

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

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, 0.979

PP5

Variant 19-41969523-C-T is Pathogenic according to our data. Variant chr19-41969523-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 161146.Status of the report is criteria_provided_single_submitter, 1 stars.
