alpha carboxylase/癲癇性発作

A 4-month-old girl presented with myoclonic seizures and an electroencephalogram showing hypsarrhythmia. Hyperglycinuria and a cerebrospinal fluid to plasma glycine ratio of 0.2 suggested the diagnosis of non-ketotic hyperglycinaemia. Propionic acid and methyl citric acid were present in the urine,

We report a 3-year-old boy with isolated 3-methylcrotonyl-coenzyme A deficiency with unexpectedly severe presentation, seizures and history of cerebral ischae-mic episode.

Multiple carboxylase deficiency is characterized by deficient activities of three biotin-dependent enzymes, propionyl coenzyme A carboxylase, pyruvate carboxylase, and beta-methylcrotonyl coenzyme A carboxylase. A newborn infant was seen with metabolic ketoacidosis, hyperammonemia, organic aciduria,

A patient with early-onset 3-methylcrotonyl coenzyme A carboxylase (MCC) deficiency showing a severe clinical course is described. Abnormal eye and head movements suggestive of seizures were noticed soon after birth. Tonic convulsions at the age of 10 weeks led to admission. Urinary organic acid

Propionic acidemia (PA) is a rare organic acidemia resulting from a deficiency of the mitochondrial enzyme propionyl-coenzyme A carboxylase. Most cases are diagnosed after the detection of metabolic abnormalities-such as hyperammonemia, metabolic acidosis, and ketosis-associated with complaints of
