Nonketotic hyperglycinemia is a disorder caused by mutations in the GLDC or AMT gene, which impair the body's ability to break down glycine and cause excess glycine to build up in tissues and organs. It is most commonly seen in elderly patients with type 2 diabetes mellitus, although it can affect people of any age. Symptoms include chorea and ballismus, which can be unilateral or bilateral and usually resolve upon normalization of glucose levels. Treatment typically involves lifestyle changes such as avoiding sugar and alcohol, as well as medications such as glucain and glycine glucosamine. MRI is the modality of choice for assessing non-ketotic hyperglycemic hemichorea and can demonstrate subtle hyperdensity in the striatal region. Symptoms and imaging findings usually resolve upon normalization of glucose levels.

Non-ketotic hyperglycinemia (NKH) is a rare, genetic, metabolic disorder caused by a defect in the enzyme system that breaks down the amino acid glycine, resulting in an accumulation of glycine in the body’s tissues and fluids. There is a classical form of NKH and a variant form of NKH.
Nonketotic Hyperglycinemia - National Organization for Rare Disorders
Nonketotic hyperglycinemia is a disorder characterized by abnormally high levels of a molecule called glycine in the body, particularly the brain. It is caused by mutations in the GLDC or AMT gene, which impair the system's ability to break down glycine and cause excess glycine to build up in tissues and organs. Treatment for nonketotic hyperglycinemia typically involves lifestyle changes such as avoiding sugar, eating a high-saturated diet, and avoiding alcohol, as well as medications such as glucain and glycine glucosamine.

Nonketotic hyperglycinemia (NKH) is an inherited condition in which the body is unable to breakdown and process some of the building blocks of protein (amino acids). It is considered an amino acid condition because it can lead to high levels of the amino acidglycine in the body.
