Abstract Some patients with maple syrup urine disease respond to thiamine administration with a reduction in ketoaciduria and increase in activity of branched-chain alpha-ketoacid dehydrogenase Maple syrup urine disease (MSUD) is caused by a gene defect. This is caused by mutations in the BCKDHA, BCKDHB and DBT genes. These three genes provide instructions for making proteins that work together as a complex Maple syrup urine disease is a rare genetic metabolic disorder where the body cannot break down branched chain amino acids like valine, leucine, and isoleucine completely, causing buildup of these amino acids and their toxic metabolic byproducts Maple Syrup Urine Disease (MSUD - also known as branched-chain ketoaciduria) is a metabolic disorder that prevents the breakdown of branched-chain amino acids in patients afflicted with the condition. Patients with the condition exhibit characteristically distinct, sweet smelling urine and earwax. MSUD is specifically caused by an inability to complete the oxidative decarboxylation of. Maple Syrup Urine Disease (MSUD) is a metabolic disease affecting branched chain amino acids. The 3 amino acids - valine, isoleucine and leucine (branched chain amino acids) is used to build proteins. For people without MSUD, the 3 amino acids will be broken down and be used as energy when they are not used to build proteins

A number sign (#) is used with this entry because maple syrup urine disease (MSUD) can be caused by homozygous or compound heterozygous mutation in at least 3 genes: BCKDHA on chromosome 19q13, BCKDHB on chromosome 6q14, and DBT on chromosome 1p21.These genes encode 2 of the catalytic components of the branched-chain alpha-keto acid dehydrogenase complex (BCKDC), which catalyzes the catabolism. Maple syrup urine disease (MSUD) is an autosomal recessive disorder caused by decreased activity of the branched-chain α-ketoacid dehydrogenase complex (BCKDC), which catalyzes the irreversible catabolism of branched-chain amino acids (BCAAs).

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 is an inherited disorder in which the body is unable to process certain amino acids properly. The condition gets its name from the distinctive sweet odor of affected infants' urine. Beginning in early infancy, this condition is characterized by poor feeding, vomiting, lethargy, and developmental delay Mnemonics: Biochemistry: maple syrup urine disease: maple syrup urine disease: Posted by sumandutta on 25-Jan-2016: 3048 people have seen this mnemonic. maple syrup urine disease: Posted by sumandutta on 25-Jan-2016: 3048 people have seen this mnemonic.
