Summaries for Alpha-Methylacetoacetic Aciduria

About this section
NIH Rare Diseases:45 Beta-ketothiolase deficiency is an inherited disorder in which the body cannot effectively process a protein building block (amino acid) called isoleucine. this condition also impairs the body's ability to process ketones, which are molecules produced during the breakdown of fats. signs and symptoms typically appear between the ages of 6 months and 24 months. affected children experience episodes of vomiting, dehydration, difficulty breathing, extreme tiredness (lethargy), and occasionally seizures. these episodes, which are called ketoacidotic attacks, sometimes lead to coma. ketoacidotic attacks are frequently triggered by infections, periods without food (fasting), or increased intake of protein-rich foods. this condition is inherited in an autosomal recessive fashion and is caused by mutations in the acat1 gene. last updated: 8/3/2011

MalaCards based summary: Alpha-Methylacetoacetic Aciduria, also known as beta-ketothiolase deficiency, is related to hypermethioninemia, persistent, autosomal dominant, due to methionine adenosyltransferase i/iii deficiency and ketothiolase deficiency, and has symptoms including autosomal recessive inheritance, intellectual disability and dehydration. An important gene associated with Alpha-Methylacetoacetic Aciduria is ACAT1 (Acetyl-CoA Acetyltransferase 1), and among its related pathways are Propanoate metabolism and Mitochondrial LC-Fatty Acid Beta-Oxidation.

Genetics Home Reference:23 Beta-ketothiolase deficiency is an inherited disorder in which the body cannot effectively process a protein building block (amino acid) called isoleucine. This disorder also impairs the body's ability to process ketones, which are molecules produced during the breakdown of fats.

UniProtKB/Swiss-Prot:67 3-ketothiolase deficiency: An inborn error of isoleucine catabolism characterized by intermittent ketoacidotic attacks associated with unconsciousness. Some patients die during an attack or are mentally retarded. Urinary excretion of 2- methyl-3-hydroxybutyric acid, 2-methylacetoacetic acid, triglylglycine, butanone is increased. It seems likely that the severity of this disease correlates better with the environmental or acquired factors than with the ACAT1 genotype.
