Summaries for ACAT1 Gene

Entrez Gene Summary for ACAT1 Gene

  • This gene encodes a mitochondrially localized enzyme that catalyzes the reversible formation of acetoacetyl-CoA from two molecules of acetyl-CoA. Defects in this gene are associated with 3-ketothiolase deficiency, an inborn error of isoleucine catabolism characterized by urinary excretion of 2-methyl-3-hydroxybutyric acid, 2-methylacetoacetic acid, tiglylglycine, and butanone. [provided by RefSeq, Feb 2009]

GeneCards Summary for ACAT1 Gene

ACAT1 (Acetyl-CoA Acetyltransferase 1) is a Protein Coding gene. Diseases associated with ACAT1 include Alpha-Methylacetoacetic Aciduria and Ketothiolase Deficiency. Among its related pathways are Butanoate metabolism and Terpenoid backbone biosynthesis. GO annotations related to this gene include protein homodimerization activity and transferase activity, transferring acyl groups other than amino-acyl groups. An important paralog of this gene is ACAT2.

  • 3-ketothiolase deficiency (3KTD) [MIM:203750]: 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. {ECO:0000269 PubMed:1346617, ECO:0000269 PubMed:1715688, ECO:0000269 PubMed:7728148, ECO:0000269 PubMed:9744475}.
