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.553C>G (p.L185V) alteration is located in exon 6 (coding exon 6) of the ATP12A gene. This alteration results from a C to G substitution at nucleotide position 553, causing the leucine (L) at amino acid position 185 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
