Exocrine pancreatic insufficiency, dyserythropoietic anemia, and calvarial hyperostosis
概要
Patients with this disease suffer from exocrine pancreatic insufficiency, dyserythropoietic anemia, and calvarial hyperostosis. Mutations in COX4I2, an essential component of cytochrome c oxidase complex expressed in acinar cells, lead to failure to absorb fat and deficiency of fat-soluble vitamins.
Shwachman-Bodian-Diamond, Pearson, and Johanson-Blizzard syndromes also show steatorrhea and malabsorption of lipid-soluble vitamin. In addition, Shwachman-Bodian-Diamond and Pearson syndromes are associated with hematologic dysfunction.
