Back to Health A to Z. It means the body cannot process certain amino acids the "building blocks" of proteincausing a harmful build-up of substances in the blood and urine. Any amino acids that are not needed are usually broken down and removed from the body.
Maple syrup urine disease MSUD is a rare genetic disorder characterized by deficiency of certain enzymes branched-chain alpha-keto acid dehydrogenase complex required to break down metabolize the three branched-chain amino acids BCAAs [Leucine, Isoleucine and Valine] in the body. The result of this metabolic failure is that all three BCAAs, along with their various byproducts, accumulate abnormally throughout the body. If untreated, symptoms begin to emerge, often within the first hours of life.
Maple Syrup Urine Disease is a life threatening condition if it is not detected and treated early. It is an autosomal recessive disorder caused by a defect in the metabolism of the three branched chain amino acids. Approximately one in everybabies born in Ireland may have this condition or about one baby every two years. The disorder is so called because the urine may have an odour similar to that of maple syrup.
MSUD is caused by the deficiency of the branched-chain alpha-keto acid dehydrogenase complex BCKADcausing abnormal accumulation of the branched-chain amino acids leucine, isoleucine and valine and their metabolic by-products, resulting in ketoacidosis in blood and urine. Diagnosis of maple syrup urine disease is based on the presence of characteristic findings such as:. Treatment for MSUD includes specific nutrition and dietary measures 1 :.
Maple syrup urine disease MSUD is a disorder in which the body cannot break down certain parts of proteins. The urine of people with this condition can smell like maple syrup. Maple syrup urine disease MSUD is inherited, which means it is passed down through families.
Maple syrup urine disease is an inherited disorder in which the body is unable to process certain protein building blocks amino acids properly. The condition gets its name from the distinctive sweet odor of affected infants' urine. It is also characterized by poor feeding, vomiting, lack of energy lethargyabnormal movements, and delayed development.

Maple syrup urine disease MSUD is an inherited condition caused by a faulty gene. In children with MSUD, the body cannot break down certain amino acids, the building blocks of protein. These amino acids and their toxic byproducts build up in the blood and urine, resulting in symptoms such as lethargy, poor appetite, seizures, and vomiting.
Maple syrup urine disease MSUD is a condition in which the body is unable to break down certain proteins. The condition is named for the sweet odor of the urine of untreated babies. MSUD is considered an amino acid condition because people with MSUD have trouble breaking down certain amino acids, the building blocks of proteins.
