Transient hyperammonemia had been detected in both initially. High levels of glycine in plasma and cerebrospinal fluid disturb the nervous system, causing variable manifestations of this disease. Both cases were complicated by intracranial hemorrhage, which has never before been reported. After treatment with sodium benzoate and dextromethorphan, some neurologic improvement was observed, although the glycine levels did not lower. Recent clinical trials are reviewed, and because of the unfavorable outcomes, the special need for prenatal diagnosis is highlighted.[SDGs]SDG3benzoic acid; dextromethorphan; article; brain hemorrhage; case report; consciousness disorder; drug effect; female; human; hyperammonemia; hyperglycinemia; male; newborn; newborn disease; priority journal; Ammonia; Brain; Female; Glycine; Humans; Infant, Newborn; Lactic Acid; Magnetic Resonance Imaging; Male; Metabolism, Inborn Errors; Muscle Hypotonia; Psychomotor Disorders; Tomography, X-Ray Computed; Treatment Outcomejournal article10.1016/S0887-8994(98)00157-X103282792-s2.0-0032939225
