hypoglycemia, seizures, lactic acidosis, hyperuricemia (high levels of a waste product called uric acid in the body), and hyperlipidemia. Affected people may also have short stature; thin arms and legs; a protruding abdomen; neutropenia (which may lead to frequent infections); inflammatory bowel disease and oral health problems. GSD1B is caused by changes (mutations) in the SLC37A4 gene and is inherited in an autosomal recessive manner. Although there is currently no cure for the condition, symptoms can often be managed with a special diet in combination with certain medications.Glycogen storage disease type 1B (GSD1B) is an inherited condition in which the body is unable to break down a complex sugar called glycogen. As a result, glycogen accumulates in cells throughout the body. In GSD1B, specifically, glycogen and fats build up within the liver and kidneys which can cause these organs to be enlarged and not function properly. Signs and symptoms of the condition generally develop at age 3 to 4 months and may include
