Maple syrup urine disease

Maple syrup urine disease (MSUD) is an autosomal recessive condition with an incidence of approximately 1 in 150 000 live births with a higher incidence amongst children from consanguineous relationships [1]. It is caused by an enzymatic deficiency with reduction in oxidative decarboxylation of branched-chain amino acids (BCAA) (leucine, isoleucine and valine) resulting in elevated levels and t...

Branched chain a-ketoacid dehydrogenase (BCKDH) deficiency results in maple syrup urine disease (MSUD). We examined the molecular basis of familial cases ofMSUD by analyzing the activity, subunit structure, mRNA sequence, and genome structure of the affected enzyme. The BCKDH activity in the proband with MSUD was 6% ofthe normal control level. Immunoblot analysis revealed that the ElB subunit o...
