Variant summary

Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PP2PP3_Moderate

The NM_152296.5(ATP1A3):c.3014G>A(p.Gly1005Asp) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.0000058 in 1,551,088 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G1005S) 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: Uncertain_significance. The variant received 3 ACMG points.

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, 0.857
