ketotic hyperglycinemia

an inherited metabolic disorder resulting from a deficiency of propionyl-CoA carboxylase PCC, the enzyme that converts propionate to methylmalonate and with biotin as a cofactor; caused by a mutation in the gene PCCA encoding propionyl-CoA on 13q or PCCB on 3q; the clinical features are episodic vomiting and lethargy with hyperammonemia, hyperglycinemia, and ketoacidosis; death may occur following seizures and coma.

Synonym(s): methylmalonic acidemia, propionic acidemia
