The initial reaction of the disease often occurs when the child experiences stress, illness, or an unusual increase in protein. Individuals have significant enzyme activity - about 8 to 15 percent of normal activity. Symptoms usually don’t appear until a child is between 1 and 2 years of age. This form doesn’t interfere with normal physical and intellectual growth and development. People with this type of MSUD have a higher level of enzyme activity than classic MSUD - about 3 to 8 percent of normal activity. Onset is usually triggered when the infant’s body begins to process protein from feedings. Symptoms are present in newborns within a few days of birth. A person with this form has little, if any, enzyme activity - about 2 percent or less of normal activity. This is the most common and severe form of the condition.
They differ by their degree of enzyme activity, severity, and the age when the disease appears. branched-chain alpha-keto acid dehydrogenase deficiency.Early diagnosis and intervention improve the chance of long-term success. The success of this method can be monitored with blood tests. MSUD can be controlled with dietary restrictions. When untreated, MSUD can cause significant physical and neurological problems. BCAAs are found in foods rich in protein, such as meat, eggs, and milk.
The BCKDC enzyme processes three important amino acids: leucine, isoleucine, and valine, also called BCAAs (branched-chain amino acids). In MSUD, the body lacks an enzyme called BCKDC (branched-chain alpha-keto acid dehydrogenase complex). As the levels of these substances increase, it can result in: If some of the necessary enzymes are missing or defective, the amino acids and their byproducts, called keto acids, collect in your body. Special enzymes process amino acids so they can be used to maintain all of your body functions. The disease prevents your body from breaking down certain amino acids.Īmino acids are what remain after your body digests protein from the food you eat. Maple syrup urine disease (MSUD) is a rare, inherited metabolic disorder.
