    Glycogen storage disease (GSD) is a rare genetic disease characterized by abnormal enzymes in the process of glycogen metabolism, resulting in the inability to synthesize or decompose glycogen.


    Glycogen storage disease (GSD) is a rare genetic disease characterized by abnormal enzymes in the process of glycogen metabolism, resulting in the inability to synthesize or decompose glycogen.


    G6Pase-α is essential for maintaining euglycemia between meals.


    GSD1a patients typically exhibit severe life-threatening low blood sugar disease and long-term liver complications, including liver cell adenoma (HCA) and hepatocellular carcinoma (HCC).


    There is currently no treatment for GSD1a, and the current standard of care is: frequent feeding (every 4-6h) uncooked or modified corn starch, and overnight glucose gavage (mainly used for young patients).

    In this study, the researchers encapsulated the engineered mRNA encoding human G6Pase-α in lipid nanoparticles (LNPs) to develop new mRNA therapies for GSD1a.

    The results showed that the effectiveness and safety of the method was confirmed in a preclinical mouse model phenotypically similar to human diseases.


    Researchers have shown that the mRNA therapy can be used to treat life-threatening hypoglycemia and reduce the long-term high risk of HCA/HCC associated with this disease.
