Since the clinic opened in September, our team is seeing patients with existing or suspected metabolic disorders for acute and chronic management. Brain amino acid requirements and toxicity: the example of leucine. Maple syrup urine disease (MSUD) is an inborn error of metabolism caused by defects in the branched-chain α-ketoacid dehydrogenase complex, which results in elevations of the branched-chain amino acids (BCAAs) in plasma, α-ketoacids in urine, and production of the pathognomonic disease marker, alloisoleucine. The classic presentation occurs in the neonatal period with developmental delay, failure to thrive, feeding difficulties, and maple syrup odor in the cerumen and urine, and can lead to irreversible neurological complications, including stereotypical movements, metabolic decompensation, and death if left untreated. The disease prevents your body from breaking down certain amino acids. The symptoms and severity of MSUD at onset varies greatly from patient to patient and largely relate to the amount of residual enzyme activity. GTR Test ID Help Each Test is a specific, orderable test from a particular laboratory, and is assigned a unique GTR accession number. Disease Management. Proteins are made up of 20 different types of amino acids. If the child inherits only one copy of the gene, they are a carrier for maple syrup urine disease but are not affected. Introduction: Maple syrup urine disease (MSUD) is an autosomal recessive disorder caused by a blockage of branched-chain keto acid of BCAA (branched-chain keto acid dehydrogenase, BCKDH) leading to neurological damage induced by accumulation of leucine and metabolites. Get the latest public health information from CDC: https://www.coronavirus.gov. Beginning in early infancy, this condition is characterized by poor feeding, vomiting, lack of energy (lethargy), seizures, and developmental delay. Genetic testing experiences and genetics knowledge among families with inherited metabolic diseases. Variant forms of the disorder become apparent later in infancy or childhood and are typically milder, but they still lead to delayed development and other health problems if not treated. Most infants with classic MSUD show subtle emerging symptoms within 2-3 days; these include poor feeding at bottle or breast and increasing lethargy and irritability. The most common and severe form of the disease is the classic type, which becomes apparent soon after birth. GeneReviews. Branched Chain Amino Acids.
