More than 50 million students study for free with Wernicke-like encephalopathy during classic maple syrup urine disease decompensation. Slide 2: Branched Chain Amino Acids (BCAAs) The branched chain amino acids, leucine, isoleucine, and valine, are essential amino acids containing aliphatic side chains of various lengths. This disease is currently treated primarily by dietary restriction of branched-chain amino acids (BCAAs). INTERNET Strauss KA, Puffenberger EG, Carson VJ. The clinical features may include neurological deficiencies, varying degrees of developmental delays, seizures , feeding issues, poor growth and urine or sweat smelling like maple syrup. In Maple syrup urine disease, the breakdown of BRANCHED amino acids (L eucine, I soleucine, and V aline) is impaired. Maple Syrup Urine Disease Quizlet is the easiest way to study, practice and master what you’re learning. Nine patients with maple syrup urine disease (MSUD), of whom eight were detected by mass-screening of neonates for inherited metabolic desease, were studied to determine possible relationships between clinical features and properties of the branched-chain α-keto acid dehydrogenase complex (BCKDH) in cultured lymphoblastoid cells. Pathophysiology Maple syrup urine disease (MSUD) is resulted due to the deficiency in Branched Chain α-Ketoacid Dehydrogenase (BCKD). Maple syrup urine disease (MSUD; OMIM 248600) is an autosomal recessive disorder characterized by impaired activity of the branched‐chain alpha‐keto acid dehydrogenase (BCKADH; EC 1.2.4.4) complex (Fig. 1. This amino acid acidopathy is due to a deficiency of the metabolic enzyme branched chain α-keto acid dehydrogenase (BCKDH) leading to a buildup of branched-chain amino acids ( leucine , isoleucine , and valine ) in the blood and urine.
