Genes affected

ATP4B (HGNC:820): (ATPase H+/K+ transporting subunit beta) 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 the beta subunit of the gastric H+, K+-ATPase. [provided by RefSeq, Jul 2008]

Ambry Genetics

Mar 01, 2024

The c.232C>T (p.R78W) alteration is located in exon 2 (coding exon 2) of the ATP4B gene. This alteration results from a C to T substitution at nucleotide position 232, causing the arginine (R) at amino acid position 78 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
