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

May 05, 2023

The c.424T>G (p.F142V) alteration is located in exon 4 (coding exon 4) of the ATP4B gene. This alteration results from a T to G substitution at nucleotide position 424, causing the phenylalanine (F) at amino acid position 142 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
