Liver transplantation is an accepted treatment modality in the management of MSUD. To our knowledge, ours is only the second successful case to date of a patient with MSUD receiving an allograft from an RLD who is a heterozygous carrier for the disease. In view of the worldwide shortage of available organs for transplantation, heterozygote to homozygote transplantation in the setting of MSUD ma...
Maple syrup urine disease (MSUD) is an autosomal recessive disease associated with high levels of branched-chain amino acids. Children with MSUD can present severe neurological damage, but liver transplantation (LT) allows the patient to resume a normal diet and avoid further neurological damage. The use of living related donors has been controversial because parents are obligatory heterozygote...
Maple Syrup Urine Disease (MSUD) is a genetically heterogeneous metabolic disorder that is transmitted in an autosomal recessive manner. According to clinical data, MSUD prevalence in Lebanon is expected to be higher than the International prevalence because of consanguineous marriage. Novel mutations are still getting detected by using DNA sequencing for mutation analysis in MSUD patients. In ...
In vitro studies have suggested that catabolism of branched chain amino acids is linked with alanine and glutamine formed in, and released from, muscle. To explore this possibility in vivo, static and kinetic studies were performed in three patients with classical, and one patient with partial, branched chain alpha-ketoacid decarboxylase deficiency (maple syrup urine disease, MSUD) and compared...
During meiosis in the filamentous fungus Neurospora crassa, unpaired genes are identified and silenced by a process known as meiotic silencing by unpaired DNA (MSUD). Previous work has uncovered six proteins required for MSUD, all of which are also essential for meiotic progression. Additionally, they all localize in the perinuclear region, suggesting that it is a center of MSUD activity. Never...
Maple syrup urine disease (MSUD) is an inherited disorder of branched chain amino acid metabolism presenting with neonatal encephalopathy, episodic metabolic decompensation, and chronic amino acid imbalances. Dietary management enables survival and reduces risk of acute crises. Liver transplantation has emerged as an effective way to eliminate acute decompensation risk. Psychiatric illness is a...
In Neurospora crassa, pairing of homologous DNA segments is monitored during meiotic prophase I. Any genes not paired with a homolog, as well as any paired homologs of that gene, are silenced during the sexual phase by a mechanism known as meiotic silencing by unpaired DNA (MSUD). Two genes required for MSUD have been described previously: sad-1 (suppressor of ascus dominance), encoding an RNA-...
BACKGROUND Maple syrup urine disease (MSUD) is an autosomal recessive disorder caused by defective activity of the branched-chain alpha-ketoacid dehydrogenase enzyme complex. Early diagnosis and management of MSUD are imperative for preventing permanent neurological impairments. In the Philippines, a 4.7 kb deletion in the dihydrolipoamide branched-chain transacylase E2 (DBT) gene has been comm...
1. Comparisons of the activity and kinetics of the branched-chain 2-oxo acid dehydrogenase in cultured skin fibroblasts from normal and classical maple-syrup-urine-disease (MSUD) subjects provide a kinetic explanation for the enzyme defect. 2. In the intact cell assays, normal fibroblasts demonstrated hyperbolic kinetics with 3-methyl-2-oxo[1-14C]butyrate as a substrate. Intact fibroblasts from...
The presenting symptoms and clinical course of 2 cases of intermittent maple syrup urine disease (MSUD) are described. Intermittent MSUD is a potentially life-threatening metabolic disorder caused by a deficiency of branched-chain a-keto acid dehydrogenase, the enzyme complex that decarboxylates the 3 branched-chain amino acids. In contrast to classic MSUD, children with the intermittent form s...
