GARD Rare
Mondo Description Beta-ketothiolase (T2) deficiency is a rare organic aciduria affecting ketone body metabolism and the catabolism of isoleucine and characterized by intermittent ketoacidotic episodes associated with vomiting, dyspnea, tachypnoea, hypotonia, lethargy and coma, with an onset during infancy or toddlerhood and usually ceasing by adolescence.
Uniprot Description An autosomal recessive 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.
Disease Ontology Description An autosomal recessive disease characterized by inability to process isoleucine and ketones, has_symptom recurrent ketoacidotic attacks in infancy marked by vomitting, lethargy, dehydration, and seizures, and has_material_basis_in mutation in the ACAT1 gene of chromosome 11q22.3 responsible for producing the ACAT1 enzyme in mitochondria, which processes isoleucine and ketones.
