Maple syrup urine disease is due to mutations in any aspect of the mitochondrial branched-chain alpha-keto acid dehydrogenase complex 8. Genetics It is inherited in an autosomal recessive pattern and various different genes have been implicated 1 Maple syrup urine disease (MSUD) is an inherited autosomal recessive brain dysmyelinating disorders due to enzymatic deficiency of branched-chain alpha-ketoacid dehydrogenase enzyme complex leading to errors in the metabolism of the branched-chains amino acids (leucine, isoleucine and valine) with their accumulation in the urine (hence the name. Purpose: We aimed to evaluate the magnetic resonance imaging (MRI) and clinical features of maple syrup urine disease (MSUD). Methods: This retrospective study consisted of 10 MSUD patients confirmed by genetic testing. All patients underwent brain MRI. Phenotype, genotype, and areas of brain injury on MRI were retrospectively reviewed MSUD, also referred to as leucinosis, is a disorder that was first reported in 1954 in a family that lost four infants within the first 3 months of their lives because of a neurodegenerative disorder. The urine of these infants had an odor resembling that of maple syrup. MSUD is a branched-chain amino-acidopathy caused by a decreased activity. Ten infants with classical maple syrup urine disease (MSUD) and two with variant MSUD had a total of 26 CT scans and 13 MR examinations of the brain during different stages of their disease. We found that inter- and intrapatient analyses of CT and MR findings at times ranging from 3 days to 7 months

MSUD, also known as branched-chain ketoaciduria, is a rare autosomal-recessive disorder of BCAA metabolism. It has an annual incidence of 1 in 180,000 live births, [ 1] with a higher prevalence in Amish, Mennonite, and Jewish children. [ 1, 2] The condition gets its name from the characteristic maple-syrup odor of the affected infant's urine Maple Syrup Urine Disease. Maple syrup urine disease is an autosomal recessive disorder caused by a defect in the oxidative decarboxylation of the branched-chain α-keto acids. As a result of this enzymatic defect, leucine, isoleucine, valine, and their corresponding keto acids accumulate in serum, cerebrospinal fluid, and urine . The classic. Search for this keyword .

Maple syrup urine disease (MSUD) is an autosomal recessive metabolic disorder caused by an inborn failure to catabolize branched-chain amino acids. We report a case of a newborn boy with MSUD. The diffusion-weighted MR imaging is more sensitive than T2-weighted imaging in showing extent of brain edema Maple Syrup Urine Disease (MSUD) is a genetic disorder in which the body is unable to metabolize (process) certain proteins (amino acids). This causes an accumulation of the protein in the body, leading to brain damage in severe cases. The affected individuals' urine, smells like maple syrup; due to which the condition is known as Maple Syrup.

Presentation: Normal at birth , Presents after disease free interval, usually within the 4-7 days of life with poor feeding, vomiting, poor weight gain, increasing lethargy. Patients in crisis often smell like maple syrup. Maple syrup odor may be difficult to identify in first days of life unless urine soaked diaper is allowed to dry Maple syrup urine disease (MSUD) is an inherited condition caused by a faulty gene. In children with MSUD, the body cannot break down certain amino acids, the building blocks of protein. These amino acids and their toxic byproducts build up in the blood and urine, resulting in symptoms such as lethargy, poor appetite, seizures, and vomiting
