  Maple Syrup Urine Disease (MSUD)
Maple Syrup Urine Disease (MSUD) was first described in 1954 in a family with four successive affected newborns.
MSUD is caused by a deficiency in the ability to decarboxylate branched-chain amino acids.
Because the diagnosis and therapy of MSUD is complex, the pediatrician is advised to manage the patient in close collaboration with a consulting pediatric metabolic disease specialist.

 Maple syrup urine disease - Genetics Home Reference
Maple syrup urine disease is an inherited disorder in which the body is unable to process certain protein building blocks (amino acids) properly.
Maple syrup urine disease can be classified by its pattern of signs and symptoms or by its genetic cause.
Mutations in the BCKDHA, BCKDHB, DBT, and DLD genes cause maple syrup urine disease.

 MDCH - Maple Syrup Urine Disease Testing
Maple syrup urine disease (MSUD) is the result of a biochemical defect in branched chain amino acid decarboxylation at the keto acid level.
The disease results in severe symptoms beginning as early as 6 days of age which can include vomiting, a constant shrill cry, and loss of appetite, and which may be followed by convulsions, coma, and respiratory problems.
MSUD is screened for by assaying leucine levels in the blood stream.

 MSUD
Maple Syrup Urine Disease (MSUD) is a disorder abnormally affecting the metabolism of amino acids.
The gene defect for MSUD is an autosomal recessive genetic trait and is unknowingly passed down from generation to generation.
The disease derives its name from the sweet, burnt sugar, or maple syrup smell of the urine.

Maple Syrup Urine Disease (MSUD) is a rare autosomal recessive inherited disorder of catabolism of the branched chain amino acids (BCAA) leucine, isoleucine, and valine and their respective branched chain ketoacids (BCKA).
Classic MSUD is due to absent activity of the mitochondrial enzyme complex-branched chain alpha-ketoacid dehydrogenase.
Because the ingestion of the branched chain amino acids exceeds metabolic requirements for growth, and catabolism of the excess amino acids is blocked, the BCAA and BCKA accumulate in blood and are excreted in the urine.

 Maple syrup urine disease - Wikipedia, the free encyclopedia
Maple syrup urine disease (MSUD) is an autosomal recessive metabolic disorder due to a deficiency of Branched chain α-keto acid dehydrogenase (BCKDH) that leads to elevated concentrations of leucine, isoleucine, and valine (branched amino acids) in the blood and urine.
Characterized by the urine having an odor similar to that of maple syrup, this results in severe mental retardation, and seizures.
Maple syrup urine disease is inherited in an autosomal recessive pattern.

Background: Maple syrup urine disease (MSUD) is an aminoacidopathy secondary to an enzyme defect in the catabolic pathway of the branched-chain amino acids leucine, isoleucine, and valine.
In 1960, Dancis et al demonstrated that the enzymatic defect in MSUD was at the level of the decarboxylation of the branched-chain amino acids.
Accumulation, of leucine in particular, causes neurological symptoms, whereas elevation of plasma isoleucine is associated with the maple syrup odor.

The MSUD Family Support Group is a non-profit 501 (c)(3) organization for those with MSUD and their families and includes health-care professionals and others interested in MSUD.
In 1983 the first MSUD Newsletter was printed and distributed throughout the United States and Canada.  The Newsletter continues to provide the latest information on the treatment of the disorder, reports on the latest research, current diet information, family news and related topics.
The MSUD Family Support Group membership now includes families and professionals worldwide.  This growing organization continues to develop resources to meet its goals of support and education.  Informed families and professionals can provide better care for the child with MSUD.  Treatment has improved and the future continues to brighten for these children and their families.

 Maple syrup urine disease
The disease is inherited as an autosomal recessive disorder, but where this would normally imply that it is caused by the mutation of a single gene, MSUD can arise from mutations in several genes.
Several efforts have been undertaken to add MSUD to the list of diseases for which newborn infants are regularly checked, but in the United States this process is largely state-dependent.
Therefore, MSUD patients must ingest special formulas that limit their dietary intake of BCAAs, and because the severity of symptoms varies greatly from person to person, diets must be carefully tailored.

MSUD is a metabolic disorder that causes amino acids from proteins to accumulate in the body, which can have a toxic effect and lead to brain swelling, neurological damage and death.
People suffering from MSUD are unable to metabolize the branched-chain amino acids leucine, isoleucine and valine, which are present in all protein foods such as meat, eggs and milk.
