Hepatic glycogen synthase (GYS2) deficiency: seven novel patients and seven novel variants

摘要

Glycogen storage disease type 0 (GSD 0) is an autosomal recessive disorder of glycogen metabolism caused by mutations in the gene manifesting in infancy or early childhood and characterized by ketotic hypoglycemia after prolonged fasting, and postprandial hyperglycemia and hyperlactatemia. GSD 0 is a rare form of hepatic glycogen storage disease with less than 30 reported patients in the literature so far.
