Function

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.[6]

Clinical significance

Disease causing variants of the ATP1A3 gene are known to cause a variety of movement disorders and epilepsies.[7] The known associations include a variety of syndromes:

1) Alternating hemiplegia of childhood (AHC)

2) Rapid onset dystonia-parkinsonism (RDP, also known as DYT12)

3) Cerebellar ataxia, Areflexia, Pes cavus, Optic atrophy and Sensorineural hearing loss (CAPOS/CAOS syndrome)

4) Developmental and epileptic encephalopathy

5) Fever induced paroxysmal weakness and encephalopathy (FIPWE)

6) Recurrent episodes of cerebellar ataxia (RECA)

7) Very early-onset schizophrenia [8]

In mice, mutations in this gene are associated with epilepsy. By manipulating this gene in the offspring of such mice, epilepsy can be avoided.[9]
