hyperglycinemia

 [hi″per-gli″sĭ-ne´me-ah]
a hereditary aminoacidopathy involving excessive glycine in the blood and urine. One form is characterized by episodic vomiting, lethargy, dehydration, ketosis, and increased susceptibility to infection; a second form by generalized hypotonia, lethargy, absence of reflexes, and periodic myoclonic jerks. Called also glycinemia.

Elevated plasma glycine concentration.

hyperglycinemia

/hy·per·gly·cin·e·mia/ (-gli″sĭ-ne´me-ah) excess of glycine in the blood or other body fluids; ketotic h. includes ketotic disorders secondary to a variety of organic acidemias; nonketotic h. is a hereditary disorder of neonatal onset, due to a defect in the glycine cleavage system, with lethargy, absence of cerebral development, seizures, myoclonic jerks, and frequently coma and respiratory failure.
