Abnormal lysosomal inclusions in liver hepatocytes but not in fibroblasts in congenital disorders of glycosylation (CDG)

Abstract

We report a retrospective electron-microscopical study of liver biopsies and fibroblast cultures of 19 patients with congenital disorders of glycosylation (CDG) of different subtypes. A constant finding in liver biopsies of all CDG-I cases was that of abnormal lysosomal lamellar inclusions in the hepatocytes, which were not found in CDG-II. None of the patients showed significant abnormalities in their fibroblasts.
