3-Hydroxyisobutyric aciduria

01/01/2022 - "This report describes new variants in HIBADH as an underlying cause of primary 3-hydroxyisobutyric aciduria and expands the clinical spectrum of this recently identified inborn error of valine metabolism. "
10/01/2006 - "3-hydroxyisobutyric aciduria (3HiB-uria) is a very rare organic aciduria that involves valine metabolism. "
10/01/1991 - "3-Hydroxyisobutyric aciduria: an inborn error of valine metabolism."
10/01/1991 - "3-Hydroxyisobutyric aciduria, a disorder of valine metabolism, has been found in a boy in whom the clinical picture was that of a typical organic acidemia with repeated episodes of ketoacidosis requiring admission to hospital and parenteral fluid therapy, along with impressive failure to thrive and chronic lactic acidemia. "
01/01/2022 - "A deficiency of 3-hydroxyisobutyric acid dehydrogenase (HIBADH) has been recently identified as a cause of primary 3-hydroxyisobutyric aciduria in two siblings; the only previously recognized primary cause had been a deficiency of methylmalonic semialdehyde dehydrogenase, the enzyme that is immediately downstream of HIBADH in the valine catabolic pathway and is encoded by the ALDH6A1 gene. "

05/01/2012 - "Mutation analysis in the ALDH6A1 gene can reveal a cause of 3-hydroxyisobutyric aciduria, which may present with only slightly increased urinary levels of 3-hydroxyisobutyric acid, if a patient is metabolically stable."
05/01/2008 - "Considering the importance of the affected enzyme activities for brain metabolism homeostasis and neurotransmision, it is suggested that increased tissue levels of 3-hydroxyisobutyric acid may contribute to the neurodegeneration of patients affected by 3-hydroxyisobutyric aciduria and possibly explain previous reports describing elevated production and excretion of lactate."

"
02/25/2000 - "The chiral metabolites 3-hydroxyisobutyric acid (HIBA) and 3-aminoisobutyric acid (AIBA) are intermediates in the pathways of L-valine and thymine and play an important role in the diagnosis of the very rare inherited metabolic diseases 3-hydroxyisobutyric aciduria (McKusick 236975) and methylmalonic semialdehyde dehydrogenase deficiency (McKusick 603178-MSDD). "

05/01/2008 - "3-Hydroxyisobutyric aciduria is an inherited metabolic disease caused by 3-hydroxyisobutyryl-CoA dehydrogenase deficiency. "
