Glycogen storage disease type I (GSD-I), also known as von Gierke disease, is an autosomal recessive disorder caused by a deficiency in microsomal glucose-6-phosphatase (G6Pase) activity. There are four distinct subgroups of this disorder, Ia, Ib, Ic, and Id. GSD-Ia is caused by mutations in the G6Pase gene. Clinical manifestations include short stature, hepatomegaly, hypoglycemia, hyperuricemia, and lactic acidemia. GSD-Ib, Ic, and Id result from deficient activity of the phosphate/ pyrophosphate transporter of G6Pase complex and is associated with neutropenia as well as hepatomegaly and hypoglycaemia.
