Exon redefinition by a point mutation within exon 5 of the glucosephosphatase gene is the major cause of glycogen storage disease type 1a in Japan.
Citrate supplementation may help prevent or ameliorate nephrocalcinosis and the development of urinary calculi. While this may affect ovulation and fertility in some females, in general fertility does not appear to be reduced [ Sechi et al ].
Glycogen storage disease type Ia: Xanthoma and diarrhea may be present. As liver biopsy is invasive, it should only be tpio when a diagnosis cannot be made using molecular genetic testing see Establishing the Diagnosis.

The disease was named after German doctor Edgar von Gierke.
A typical requirement for a young child is 1. Human granulocyte colony-stimulating factor G-CSF can be used to treat recurrent infections:. Hypoglycemia is the central clinical problem, the one that is most damaging, and the one that most often prompts the initial diagnosis. For G6PD pathogenic variant p. The frequency of multi exon deletions is unknown; very few have been reported in either of these genes [ Janecke et alWang et al ].

GSDI should be suspected in individuals with the following clinical, laboratory, and histopathologic features. Evidence suggests that the neutropenia in those with GSDIb may be caused by increased apoptosis and migration of the neutrophils to inflamed tissues rather than by impairment in glycogenosis [ Visser et alKishnani et al ].
