Abstract. Glycogen storage disease type 1 (GSD-1) is a group of autosomal recessive disorders caused by deficiencies in glucose-6-phosphatase (G6Pase) and the associated substrate/product transporters. Molecular genetic studies have demonstrated that GSD-1a and GSD-1b are caused by mutations in the G6Pase enzyme and a glucose-6-phosphate transporter (G6PT), respectively. While kinetic studies of G6Pase catalysis predict that the index GSD-1c patient is deficient in a pyrophosphate/phosphate transporter, the existence of a separate locus for GSD-1c remains unclear. We have previously shown that the G6Pase gene of the index GSD-1c patient is intact; we now show that the G6PT gene of this patient is normal, strongly suggesting the existence of a distinct GSD-1c locus.
