[Medline]. • Propionyl-CoA carboxylase deficiency or propionic acidemia, an inherited metabolic disorder, is due to deficient propionyl-CoA carboxylase activity and usually presents during infancy and early childhood with neurologic symptoms, metabolic acidosis, hyperammonemia, and organic aciduria.

The next year, deficient propionyl-CoA carboxylase activity was shown in the fibroblasts of an affected patient (Hsia et al 1971). 2005 Sep 27. Mol Genet Metab. One locus, on chromosome 13, controls synthesis of the α subunit of the tetrameric enzyme apoprotein; the second locus, on chromosome 3, controls synthesis of the β subunit.

Death can occur at any time from an acute episode. 2006; 29(2-3): 299-303. Symptoms most commonly become apparent during the first weeks of life and may include abnormally diminished muscle tone (hypotonia), poor feeding, vomiting, listlessness (lethargy), dehydration and seizures.

Functional characterization of novel genotypes and cellular oxidative stress studies in propionic acidemia. Transplantation. 7. Terms and Conditions Methylmalonic and propionic acidemias: clinical management update. Although less-severely affected patients have been reported, most individuals with propionic acidemia have a classic presentation and course and a guarded prognosis. These blood abnormalities can cause various symptoms, such as immune deficiency or bleeding problems. Propionic acidemia, also known as propionic aciduria or propionyl-CoA carboxylase deficiency, is a rare autosomal recessive metabolic disorder, classified as a branched-chain organic acidemia. Rarely, the condition may become apparent later in life and may be associated with less severe symptoms and findings. In infants with severe disease (e.g., severe acidosis, hyperammonemia), treatment may require procedures that remove excess waste products from the blood (hemodialysis). J Inherit Metab Dis. 2012; 35(1): 51-63. Repetitive hyperammonemia causes neurotoxicity with neuronal cell death leading to mental retardation. Propionyl-CoA carboxylase deficiency was shown in the liver extracts of another patient (Gompertz et al 1970). 80(1 Suppl):S135-7. The pancytopenia commonly seen after clinical presentation renders the patient vulnerable to infection, which may become overwhelming and result in death.
