General

Maple syrup urine disease is an autosomal recessive disorder that affects the amino acid metabolism. The disease is caused by a defect in the branched-chain alpha-keto acid dehydrogenase complex which blocks oxidative decarboxylation. The result is a rising concentration of branched-chain amino acids. MSUD is caused by mutations in the gene coding for the alpha subunit of the branched-chain keto acid dehydrogenase(BCKDHA).

HGMD

Searching for "BCKDHA" a total of 39 mutations are reported, comprised of the following mutation types:

  • missense/nonsense: 33 mutations
  • small deletions: 3 mutations
  • small insertions: 1 mutation
  • gross deletions: 1 mutation
  • complex rearrangements: 1 mutation

For us the missense/nonsense mutations are the most interesting ones, as a single nucleotide change can lead to the phenotype of Maple Syrup Urine Disease.
