GM3 synthase deficiency is an inherited condition caused by a faulty gene. Children with GM3 synthase deficiency lack an enzyme the body needs to produce a type of fat called GM3 ganglioside. Without this fat the brain is unable to develop and function normally.
Only 7 families with 14 affected children have been reported. Here, we report an additional patient with this deficiency. Findings in this patient were clinically and biochemically consistent with those reported in patients with ketotic hypoglycemia and may alert the clinician to consider glycogen synthase deficiency.
Of note, the appellation of “glycogen storage disease” for GSD 0 is actually a misnomer; this is a disorder of glycogen formation rather than of aberrant glycogen breakdown. In GSD 0, the lack of glycogen synthase activity leads to a decrease in hepatic glycogen content. Glycogen synthase deficiency is a rare cause of hypoglycemia in childhood.We studied a 17 mo.old male infant whose AM blood glucose (BG) was 18 mg/dl during an evaluation for seizures. Family hx Glycogen-storage disease type 0 (GSD-0), or glycogen synthetase deficiency, commonly appears in infancy and early childhood with fasting hypoglycemia accompanied by ketosis and low normal reference range blood levels of lactate and alanine. Background: Glycogen synthase deficiency (glycogen storage disease 0 - GSD 0) caused by mutations in the GYS2 gene is characterized by a lack of glycogen synthesis in the liver. It is a rare GM3 synthase deficiency is an inherited condition caused by a faulty gene.

Glycogen storage disease type 0 (GSD 0, MIM 240600), also known as aglycogenosis, is an autosomal recessive disease caused by genetic defects in glycogen synthase. The overall frequency of GSDs is approximately 1/25000‐1/20000 newborns.
It caused stunted growth and severe fasting hypoglycemia with ketonuria. Mental retardation was reported in the three children who survived past infancy. The liver was virtually devoid of glycogen and … Glycogen Synthase Deficiency. Glycogen Storage Diseases Handbook.
2019-01-24 · Enzyme deficiency results in glycogen accumulation in tissues. In many cases, the defect has systemic consequences, but in some cases, the defect is limited to specific tissues. Most patients experience muscle symptoms, such as weakness and cramps, although certain GSDs manifest as specific syndromes, such as hypoglycemic seizures or cardiomegaly.

The glycogen storage diseases comprise several inherited diseases caused by abnormalities of enzymes that regulate the synthesis or degradation of glycogen. In contrast to the classic hepatic glycogen storage diseases that are characterized by fasting hypoglycemia and hepatomegaly, the liver is not enlarged in GSD0.
Citation on PubMed Glycogen can be synthesized in the absence of glycogenin, and glycogenin-1 deficiency is not compensated for by upregulation of functional glycogenin-2. Absence of glycogenin-1 leads to the focal accumulation of glycogen and polyglucosan in skeletal muscle fibers. In glycogen synthase deficiency, glycogenin-1 is autoglucosylated, as shown by the reduction in molecular weight after alpha-amylase treatment, but glycogen is not formed.
