Genes affected

ATP12A (HGNC:13816): (ATPase H+/K+ transporting non-gastric alpha2 subunit) The protein encoded by this gene belongs to the family of P-type cation transport ATPases. This gene encodes a catalytic subunit of the ouabain-sensitive H+/K+ -ATPase that catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. It is also responsible for potassium absorption in various tissues. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]

The c.239G>A (p.S80N) alteration is located in exon 4 (coding exon 4) of the ATP12A gene. This alteration results from a G to A substitution at nucleotide position 239, causing the serine (S) at amino acid position 80 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
