Amino acid disorders are caused by the body's inability to breakdown or metabolize certain amino acids in proteins, or by the inability to detoxify the by-product of amino acids (ammonia) through the urea cycle. The buildup of amino acids and/or by-products of amino acid metabolism in the blood cause severe medical complications. The presentation
