Description

An extremely rare inherited amino acid metabolic disorder characterized by a distinctive sweet odor of the urine and sweat. It is caused by deficient activity in the oxidative decarboxylation pathway of leucine, isoleucine, valine, and the corresponding keto acids in body fluids. Life-threatening complications that may occur in apparently normal infants are severe hypotonia, lethargy, feeding difficulty, and hypoglycemia. If left untreated, the disease may progress to coma. Most untreated infants die within a year. Inheritance is autosomal recessive.
