✦ Synopsis

Forty-eight patients with glycogen storage disease type Ia (GSD Ia) were studied. Using a combination of single-strand conformation polymorphism (SSCP) analysis, restriction enzyme digestion and direct sequencing, we were able to identify 93/96 mutant alleles, comprising 23 different mutations in the glucose-6-phosphatase gene (G6PC). Among these, 7 are novel mutations of G6PC: M5R, T111I, A241T, C270R, F322L, and two deletions, 793delG and 872delC, resulting in the same mutation at the amino acid level, fs300Ter (300X).

Glycogen Storage Disease type II (GSDII) is caused by the deficiency of lysosomal a-glucosidase (acid maltase). This paper reports on the characterization of the molecular defects in 6 infantile patients from Turkish ancestry. Five of the 6 patients had reduced levels of the lysosomal a-glucosidase

Three novel mutations, Q54P, W70X and T108I, were identified in the gene encoding glucose-6phosphatase in three patients with glycogen storage disease type Ia. Two sibs of Portuguese origin were homozygous for the Q54P mutation whereas the third patient, originating from both France and Lebanon, was

Several different mutations in the glycogen-debranching enzyme gene AGL have been found in patients with glycogen storage disease type III (GSD III) to date, but no missense mutations have been reported for GSD III, only nonsense, splicing, and deletion/insertion lesions. Here we describe a novel G1
