Alternative titles and symbols : Ketoacidosis due to scot deficiency; Succinyl-coa:3-ketoacid coa-transferase deficiency; Succinyl-coa:acetoacetate transferase deficiency; Scot deficiency;
Description : Ketone bodies are major vectors of energy transfer from the liver to extrahepatic
tissues and are the main source of lipid-derived energy for the brain. Mitchell et
al. (1995) reviewed medical aspects of ketone body metabolism, including the differential
diagnosis of abnormalities. As the first step of ketone body utilization, succinyl-CoA:3-oxoacid
CoA transferase (SCOT, or OXCT1; EC 2.8.3.5) catalyzes the reversible transfer of
CoA from succinyl-CoA to acetoacetate.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the 3-oxoacid CoA transferase 1 gene (OXCT1, 601424.0001);
Laboratory abnormalities : Normal plasma amino acids; Normal lactate; Low-to-normal carnitine; Normal plasma glucose; Succinyl-CoA: 3-oxoacid-CoA transferase (SCOT) deficiency; Hyperketonemia (3-hydroxybutyrate and acetoacetate) (permanent between attacks); Ketonuria (3-hydroxybutyrate and acetoacetate) (permanent between attacks); Normal ammonia;
