A mild bleeding tendency with characteristics of the von Willebrand disease was documented in family members of a girl with glycogen storage disease type Ib (GSD) Ib). It was assumed that a defective glucose-6-phosphate dependent microsomal glycoprotein synthesis was involved in the bleeding disorde

โฆ Synopsis
Glycogen storage disease type Ib has all the clinical manifestations of glycogen storage disease type Ia such as hepatomegaly, growth retardation, bleeding tendency, hypoglycemia, hyperlactacidemia, hyperuricemia, hyperlipidemia, impaired platelet function plus neutropenia. The overall glucose-6-phosphatase activity in disrupted microsomes from liver is normal whereas glucose-6-phosphate translocase, the first enzyme in the glucose-6-phosphate transport system is absent. There is no glucose-6-phosphatase activity in vivo. Recent results show that in granulocytes the glucose-6-phosphate-dependent hexosemonophosphate-shunt is impaired.

Glycogen storage disease type 1b (GSD-1b) is due to an autosomal recessive inborn error of carbohydrate metabolism caused by defects in glucose-6-phosphatase translocase. Patients with GSD-1b have severe hypoglycemia with several clinical manifestations of hepatomegaly, obesity, a doll-like face, an
