Genes affected
ATP4A (HGNC:819): (ATPase H+/K+ transporting subunit alpha) The protein encoded by this gene belongs to a family of P-type cation-transporting ATPases. The gastric H+, K+-ATPase is a heterodimer consisting of a high molecular weight catalytic alpha subunit and a smaller but heavily glycosylated beta subunit. This enzyme is a proton pump that catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. It is also responsible for gastric acid secretion. This gene encodes a catalytic alpha subunit of the gastric H+, K+-ATPase. [provided by RefSeq, Jul 2008]

The c.2060C>T (p.S687L) alteration is located in exon 14 (coding exon 14) of the ATP4A gene. This alteration results from a C to T substitution at nucleotide position 2060, causing the serine (S) at amino acid position 687 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
