Preferred Label : Beta-ureidopropionase deficiency;
Symbol : UPB1D;
CISMeF acronym : UPB1D;
Type : Phenotype, molecular basis known;
Description : Beta-ureidopropionase deficiency is a very rare autosomal recessive inborn error of
metabolism due to a defect in pyrimidine degradation. Less than 10 patients have been
reported, and the phenotype can range from severe neurologic involvement with mental
retardation and seizures to normal neurologic development (Yaplito-Lee et al., 2008).;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the beta-ureidopropionase gene (UPB1, 606673.0001);
Laboratory abnormalities : Increased urinary dihydropyrimidines; Increased urinary, plasma, and CSF N-carbamyl-beta-alanine; Increased urinary, plasma, and CSF N-carbamyl-beta-aminoisobutyric acid; Increased urinary, plasma, and CSF dihydrouracil; Increased urinary, plasma, and CSF dihydrothymine; Absence of beta-ureidopropionase activity and protein in liver biopsy;
