There are 3 cases of liver type glycogen storage diseases. All of them presented with protruding abdomen, failure to thrive, doll face and mark hepatomegaly. Laboratory findings were hypoglycemia, metabolic acidosis, abnormal liver function test, hyperlipidemia and prolonged bleeding time in GSD Ia. GSD III has no hypoglycemia and borderline hyperuricemia. Glucagon stimulation test helps to differentiate typing. The aim of treatment is to prevent hypoglycemia, suppress lactic acid production, decrease blood lipid and uric acid levels and enhances statural growth by uncooked cornstarch. Complications such as epistaxis and suspected liver adenoma have to be closely followed up. Genetic counseling for both types GSD are autosomal recessive with recurrence risk of 25%. Prenatal diagnosis by enzymes assay or molecular diagnosi are not available in this hospital.
