Clinical Significance
Gastric Parietal Cell Antibodies are found in 90% of patients with pernicious anemia. They are also found in autoimmune chronic atrophic gastritis preceding pernicious anemia. The antigenic target is the H+/K+ ATPase gastric proton pump responsible for parietal cell acid generation in the stomach.
