Homo sapiens

Also known as T2; MAT; ACAT; THIL

Gene ID: 38 | Gene type: protein coding

About ACAT1

Cytogenetic location: 11q22.3 Genomic coordinates (GRCh38): 11:108,116,705-108,147,603 (from NCBI)

This gene has 22 transcripts (splice variants), 202 orthologues, 4 paralogues and is associated with 3 phenotypes. Broad expression in liver (RPKM 166.9), kidney (RPKM 164.2) and 24 other tissues.

Summary

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.
