Liver cirrhosis treated by living donor liver transplantation in a patient with AGL mutation c.2607-2610delATTC and c.1672dupA.

Glycogen storage disease type III (GSD III) is an inherited disorder characterized by the accumulation of abnormal glycogen in the liver. Hepatic manifestations were considered as improving with age; however, patients live longer and liver cirrhosis is being recognized. We report a patient of GSD IIIa with liver cirrhosis, which was treated successfully by living donor liver transplantation. The patient proved to be a compound heterozygote for a novel small deletion c.2607-2610delATTC and a known duplication c.1672dupA in AGL, a gene coding glycogen debranching enzyme responsible for GSD III. Molecular diagnosis helped clinical decision-making.
