Glycogen storage disease type I (also known as GSDI or von Gierke disease) is an inherited disorder caused by the buildup of a complex sugar called glycogen in the body's cells. The accumulation of glycogen in certain organs and tissues, especially the liver, kidneys, and small intestines, impairs their ability to function normally.
Signs and symptoms of this condition typically appear around the age of 3 or 4 months, when babies start to sleep through the night and do not eat as frequently as newborns. Affected infants may have low blood sugar (hypoglycemia), which can lead to seizures. They can also have a buildup of lactic acid in the body (lactic acidosis), high blood levels of a waste product called uric acid (hyperuricemia), and excess amounts of fats in the blood (hyperlipidemia). As they get older, children with GSDI have thin arms and legs and short stature. An enlarged liver may give the appearance of a protruding abdomen. The kidneys may also be enlarged. Affected individuals may also have diarrhea and deposits of cholesterol in the skin (xanthomas).
People with GSDI may experience delayed puberty. Beginning in young to mid-adulthood, affected individuals may have thinning of the bones (osteoporosis), a form of arthritis resulting from uric acid crystals in the joints (gout), kidney disease, and high blood pressure in the blood vessels that supply the lungs (pulmonary hypertension). Females with this condition may also have abnormal development of the ovaries (polycystic ovaries). In affected teens and adults, tumors called adenomas may form in the liver. Adenomas are usually noncancerous (benign), but occasionally these tumors can become cancerous (malignant).
Researchers have described two types of GSDI, which differ in their signs and symptoms and genetic cause. These types are known as glycogen storage disease type Ia (GSDIa) and glycogen storage disease type Ib (GSDIb). Two other forms of GSDI have been described, and they were originally named types Ic and Id. However, these types are now known to be variations of GSDIb; for this reason, GSDIb is sometimes called GSD type I non-a.
Many people with GSDIb have a shortage of white blood cells (neutropenia), which can make them prone to recurrent bacterial infections. Neutropenia is usually apparent by age 1. Many affected individuals also have inflammation of the intestinal walls (inflammatory bowel disease). People with GSDIb may have oral problems including cavities, inflammation of the gums (gingivitis), chronic gum (periodontal) disease, abnormal tooth development, and open sores (ulcers) in the mouth. The neutropenia and oral problems are specific to people with GSDIb and are typically not seen in people with GSDIa.
MalaCards based summary : Glycogen Storage Disease Ia, also known as glycogen storage disease type i, is related to g6pc3 deficiency and fanconi-bickel syndrome, and has symptoms including intermittent diarrhea An important gene associated with Glycogen Storage Disease Ia is G6PC (Glucose-6-Phosphatase Catalytic Subunit), and among its related pathways/superpathways are Glycolysis / Gluconeogenesis and Carbohydrate digestion and absorption. The drugs Hydrocortisone and Hydrocortisone acetate have been mentioned in the context of this disorder. Affiliated tissues include liver, kidney and small intestine, and related phenotypes are hepatomegaly and short stature Disease Ontology : 12 A glycogen storage disease that has material basis in deficiency of the glucose-6-phosphatase enzyme which impairs the ability of the liver to produce free glucose from glycogen and from gluconeogenesis and is characterized by accumulation of glycogen and fat in the liver and kidneys, resulting in hepatomegaly and renomegaly. NIH Rare Diseases : 52 Glycogen storage disease type 1 is an inherited disorder caused by the buildup of a complex sugar called glycogen in the body's cells . The accumulation of glycogen in certain organs and tissues , especially the liver, kidneys, and small intestines, impairs their ability to function normally. Researchers have described two types of glycogen storage disease type 1, which differ in their signs and symptoms and genetic cause. These types are known as glycogen storage disease type IA and glycogen storage disease type IB. Glycogen storage disease type 1A is characterized by growth retardation leading to short stature and accumulation of glycogen and fat in the liver and kidneys. Although some newborns present with severe hypoglycemia , it is more common for infants to present at age three to four months with hepatomegaly , lactic acidosis , hyperuricemia , hyperlipidemia, and/or hypoglycemic seizures . Untreated children typically have doll-like faces with fat cheeks and relatively thin extremities. Xanthoma and diarrhea may be present. Impaired platelet function can lead to a bleeding tendency, making epistaxis a frequent problem. Glycogen storage disease type 1A is caused by the deficiency of glucose-6-phosphatase (G6Pase) catalytic activity which results from mutations in the G6PC gene . This condition is inherited in an autosomal recessive pattern. OMIM : 56 Glycogen storage disease type I, also known as von Gierke disease, typically manifests during the first year of life with severe hypoglycemia and hepatomegaly caused by the accumulation of glycogen. Affected individuals exhibit growth retardation, delayed puberty, lactic acidemia, hyperlipidemia, hyperuricemia, and in adults a high incidence of hepatic adenomas (summary by Lei et al., 1993). (232200) KEGG : 36 Glycogen storage disease type I (GSD-I), also known as von Gierke disease, is an autosomal recessive disorder caused by a deficiency in microsomal glucose-6-phosphatase (G6Pase) activity. There are four distinct subgroups of this disorder, Ia, Ib, Ic, and Id. GSD-Ia is caused by mutations in the G6Pase gene. Clinical manifestations include short stature, hepatomegaly, hypoglycemia, hyperuricemia, and lactic acidemia. GSD-Ib, Ic, and Id result from deficient activity of the phosphate/ pyrophosphate transporter of G6Pase complex and is associated with neutropenia as well as hepatomegaly and hypoglycaemia. UniProtKB/Swiss-Prot : 73 Glycogen storage disease 1A: A metabolic disorder characterized by impairment of terminal steps of glycogenolysis and gluconeogenesis. Patients manifest a wide range of clinical symptoms and biochemical abnormalities, including hypoglycemia, severe hepatomegaly due to excessive accumulation of glycogen, kidney enlargement, growth retardation, lactic acidemia, hyperlipidemia, and hyperuricemia.
