N-acetylglutamate synthetase deficiency

Overview

Type of disease: Rare conditions

N-acetylglutamate synthase deficiency is type of urea cycle disorder. It causes toxic levels of ammonia to accumulate in the blood. Signs and symptoms in newborns may include a lack of energy, unwillingness to eat, seizures, unusual body movements, and poorly controlled breathing or body temperature. Complications may include coma, developmental delay, and learning disability. Some people have a less severe form of the deficiency with earliest symptoms manifesting later in life, particularly following high-protein meals, illness, or other stress. Signs and symptoms may include sudden vomiting, lack of coordination, confusion, and coma. N-acetylglutamate synthase deficiency is caused by mutations in the NAGS gene and is inherited in an autosomal recessive fashion.Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
