Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 1P and 11B. PP2BP4_ModerateBP6BS1BS2

The NM_152296.5(ATP1A3):c.1387C>T(p.Arg463Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000647 in 1,614,084 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R463H) 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 was made for transcript

Our verdict: Benign. The variant received -10 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.20119265).

BP6

Variant 19-41981552-G-A is Benign according to our data. Variant chr19-41981552-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 377531.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00048 (73/152190) while in subpopulation NFE AF = 0.000808 (55/68038). AF 95% confidence interval is 0.000638. There are 0 homozygotes in GnomAd4. There are 39 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2
