METHODS There are considerable uncertainty and debate regarding all aspects of newborn screen-positive cases of 3-methylcrotonyl-CoA carboxylase deficiency (3-MCCD), including diagnostic criteria, clinical spectrum, morbidity, prognosis, and appropriate management. To address some of these

Changes in the carboxyl terminus of the beta subunit of human propionyl-CoA carboxylase affect the oligomer assembly and catalysis: expression and characterization of seven patient-derived mutant forms of PCC in Escherichia coli.

Propionyl-CoA carboxylase (PCC) catalyzes the biotin-dependent carboxylation of propionyl-CoA to d-methylmalonyl-CoA in the mitochondrial matrix. Human PCC is a dodecamer composed of pairs of nonidentical alpha and beta subunits encoded by PCCA and PCCB genes, respectively. Deficiency of PCC results

A new patient with neonatal lactic acidosis due to pyruvate carboxylase deficiency is described. Since birth he developed vomiting, hypothermia, lethargy, irritability, hypoglycemia and severe metabolic acidosis. During admission a progressive deterioration was observed. Despite different attempted

OBJECTIVE Multiple carboxylase deficiency (MCD) is an autosomal recessive disorder. MCD is characterized by skin rash, metabolic acidosis, vomiting and psychomotor retardation. Depending on deficiency of the enzyme, MCD includes two different forms, biotinidase deficiency (BTD, OMIM 253260) and

3-Methylcrotonyl-CoA carboxylase deficiency newborn screening in a population of 536,008: is routine screening necessary?

Objective To evaluate whether 3-methylcrotonyl-CoA carboxylase deficiency (3-MCCD) should be routinely screened in newborns. Methods Dried blood spots (DBS) were collected and analyzed by tandem mass spectrometry (TMS). Blood samples were collected from infants with positive 3-MCCD results. Targeted

Propionyl CoA carboxylase deficiency was found in a 7-month-old boy who presented with attacks of vomiting, anorexia, weight loss, weakness, and hypotonia. He failed to thrive and had generalized seizures. He had propionic acidemia and hyperglycinemia; these are the manifestations of the ketotic

Two children are described who suffered from episodes of metabolic acidosis and progressive mental and motor deterioration. The patients showed periodic elevation of blood lactate, pyruvate and alanine, which was accompanied by vomiting, hypotonia or convulsions. The concentrations of lactate and

Dysautonomia in an infant with secondary hyperammonemia due to propionyl coenzyme A carboxylase deficiency.

Only registered users can translate articles

A male infant who had vomiting and coma in the absence of ketoacidosis was initially thought to have dysautonomia because of abnormal responses to methacholine and histamine, as well as abnormal urinary catecholamine excretion. Following an episode of hyperammonemia, a liver biopsy was performed

Propionyl-CoA carboxylase - A review.

Only registered users can translate articles

Propionyl-CoA carboxylase (PCC) is the enzyme which catalyzes the carboxylation of propionyl-CoA to methylmalonyl-CoA and is encoded by the genes PCCA and PCCB to form a hetero-dodecamer. Dysfunction of PCC leads to the inherited metabolic disorder propionic acidemia, which can result in an affected

Propionic acidemia: a neuropathology case report and review of prior cases.

Only registered users can translate articles

Propionic acidemia is a disorder of branch-chain amino acid and odd-chain fatty acid metabolism. The clinical features typically begin shortly after birth, with rare cases presenting in young adulthood. This disorder most commonly is characterized by episodic decompensations with dehydration,
