Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP2BP4_Moderate

The NM_152296.5(ATP1A3):​c.1654G>A​(p.Glu552Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,454,698 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E552Q) 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 made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ATP1A3. . Gene score misZ 6.3327 (greater than the threshold 3.09). Trascript score misZ 9.1232 (greater than threshold 3.09). GenCC has associacion of gene with 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.
BP4
Computational evidence support a benign effect (MetaRNN=0.2004497).
