MPI-CDG is a rare congenital disorder of glycosylation (CDG) which presents with hepato-gastrointestinal symptoms and hypoglycemia. We report on hepatic evaluation of two pediatric patients who presented to us with gastrointestinal symptoms. Analysis of carbohydrate deficient transferrin (CDT) showed a Type 1 pattern and molecular analysis confirmed the diagnosis of MPI-CDG. Oral mannose therapy was markedly effective in one patient but was only partially effective in the other who showed progressive portal hypertension.
Keywords: MPI‐CDG; genetic variants; liver involvement; mannose; portal hypertension.
