Abstract excerpt
A patient with maple syrup urine disease (MSUD) associated with a E1 beta subunit deficiency of the branched-chain alpha-keto acid dehydrogenase (BCKDH) complex was investigated at the molecular level. The defect responsible for the deficiency of the E1 beta subunit protein was identified by analysis of cDNA and genomic DNA by polymerase chain reaction. Total RNA isolated from lymphoblastoid cells was transcribed...
