an enzyme catalyzing the thioclastic cleavage by coenzyme A of β-ketoacyl-CoA, forming an acyl-CoA with a carbon chain shorter by two atoms, the missing two atoms appearing as acetyl-CoA. A step in fatty acid degradation.

Based on specific evaluation criteria, the disorders were ranked from 1 (highest priority) to 29, with Medium-chain acyl-CoA dehydrogenase deficiency (MCADD) being first in the ranking and Beta-ketothiolase (BKT) ranking number 29 (ACMG, 2005).
