Variant summary
Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2PP2PP3_Strong
The NM_152296.5(ATP1A3):c.1003A>C(p.Thr335Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. T335T) has been classified as Likely benign.

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 made for transcript
Verdict is Likely_pathogenic. Variant got 7 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 dystonia 12, alternating hemiplegia of childhood 2, ATP1A3-associated neurological disorder, developmental and epileptic encephalopathy 99, alternating hemiplegia of childhood, cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss syndrome, alternating hemiplegia of childhood 1, encephalopathy, acute, infection-induced.
PP3
