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]

Alternating hemiplegia of childhood 2 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Victorian Clinical Genetics Services, Murdoch Childrens Research Institute | Nov 07, 2014 | This variant causes a deletion of an arginine at position 849, and a substitution of a leucine for a serine at position 850, p.(Arg849_Ile850delinsSer). The arginine at position 849 is highly conserved and in the transmembrane domain. This deletion is predicted to be disease-causing by in-silico software and is nove. The leucine at position 850 is highly conserved and in the transmembrane domain. Grantham assessment is deleterious due to conservation and amino acid properties. This substitution is predicted to be disease-causing by in-silico software and is novel. The sequencing data indicates this is a complex variant located on the same strand. Parental testing confirmed the variant to be de novo. - |
