BACKGROUND: Familial occurrence of Ménétrier disease is rare and has been reported only in few instances. METHODS: Affected patients from a large pedigree were evaluated at the clinical, endoscopic, and pathological levels. RESULTS: Affected members presented with gastropathy of variable severity but without protein loss. Endoscopy and pathology findings were consistent with Ménétrier disease; however, gastric transforming growth factor α (TGF-α) immunohistochemistry and real-time polymerase chain reaction showed no increase in TGF-α expression. CONCLUSIONS: We describe a unique, 4-generation pedigree with autosomal dominant gastropathy exhibiting the typical clinical, endoscopic, and pathological findings of Ménétrier-like disease, though in the absence of protein loss and with no increase in the levels of gastric TGF-α. Members of this family may be affected by a novel and previously unrecognised hereditary form of gastric hyperplasia.
