Glutathione synthetase deficiency, an inborn error of metabolism involving the gamma-glutamyl cycle in patients with 5-oxoprolinuria (pyroglutamic aciduria).

Enzyme studies on placenta, cultured skin fibroblasts, and erythrocytes from two sisters with the inborn error 5-oxoprolinuria (pyroglutamic aciduria) indicate that the metabolic lesion in this disease is at the glutathione synthetase (EC 6.3.2.3) step of the gamma-glutamyl cycle. Excessive urinary excretion of 5-oxoproline by these patients appears to be associated with increased synthesis of ...

Transient 5-oxoprolinuria (pyroglutamic aciduria) with systemic acidosis in an adult receiving antibiotic therapy.

5-Oxoprolinuria is a recognized condition with increased urinary excretion of 5-oxoproline and is associated with a variety of inborn metabolic defects involving the series of enzyme-linked reactions known as the gamma-glutamyl cycle. We report the unusual case of a 35-year-old woman who initially presented with staphylococcal pneumonia but went on to develop a transient high anion gap metaboli...

Argininosuccinic aciduria, an inborn error of amino acid metabolism.

It is probable that many, if not all, of the inherited ('inborn') metabolic disturbances result from a specific enzyme defect, arising from a single abnormal gene. Examples are now known of a number of such inherited defects, some involving amino acids, which result in a block of a metabolic pathway. For example, the normal pathway for the metabolism of phenylalanine and tyrosine is by a series...

Asparagine Synthetase Deficiency: New Inborn Errors of Metabolism.

BACKGROUND Asparagine synthetase deficiency (ASD) is a newly identified neurometabolic disorder characterized by severe congenital microcephaly, severe global developmental delay, intractable seizure disorder, and spastic quadriplegia. Brain MRI showed brain atrophy, delayed myelination, and simplified gyriform pattern. METHODS We report ASD deficiency in a 2- and 4-year-old sibling. On them,...

Selective screening of 650 high risk Iranian patients for detection of inborn error of metabolism

Objective: Although metabolic diseases individually are rare ,but overall have an incidence of 1/2000 and can cause devastating and irreversible effect if not diagnosed early and treated promptly. selective screening is an acceptable method for detection of these multi presentation diseases.Method: using panel neonatal screening for detection of metabolic diseases in 650 high risk Iranian patie...
