GSD type 1 is diagnosed by identification of proband by either of the following:[1]

  • Molecular genetic testing
  • Enzyme Activity Assay

Molecular genetic testing

  • Molecular genetic testing shows:
    • Biallelic pathogenic variants in G6PC for patients with GSD type 1a
    • Biallelic pathogenic variants in SLC37A4 for patients with GSD type 1b
