Summary
The maple syrup urine (MSUD) disease is an autosomal recessive disorder which is caused by a disturbance in the amino acid metabolism. The symptomes of MSUD are mental and physical retardation, feeding problems, vomiting, dehydration, lethargy, hypotonia, seizures, hypoglycaemia, ketoacidosis, opisthotonus, pancreatitis, coma and neurological decline. If the disease remains unrecognized it can also lead to brain damage and in the last resort to death. The most characteristical symptome is the sweet smell of the urine, just like maple syrup.
Phenotype
The MSUD occurs because of a defect in the branched-chain alpha-keto acid dehydrogenase complex (BCKDC). This defect leads to a block in oxidative decarboxylation which results in a rising concentration of branched-chain amino acids and their toxic by-products in blood and urine.
