Urea Cycle Enzyme Deficiencies Blood Ammonia Level Chart In milder or partial urea cycle enzyme deficiencies ammonia accumulation may be triggered by illness or stress at almost any time of life resulting in multiple mild to moderately severe elevations of plasma ammonia concentration The hyperammonemia is usually less severe and the symptoms more subtle than in severe urea cycle enzyme
Urea cycle disorders UCDs are inborn errors of ammonia detoxification arginine synthesis due to defects affecting the catalysts of the Krebs Henseleit cycle five core enzymes one activating enzyme and one mitochondrial ornithine citrulline antiporter with an The urea cycle is a critical metabolic pathway responsible for converting toxic ammonia into urea which is then excreted from the body via urine When this cycle is disrupted it can lead to an accumulation of ammonia in the blood resulting in serious neurological and

Urea cycle disorders UCDs are inborn errors of ammonia detoxification arginine synthesis due to defects affecting the catalysts of the Krebs Henseleit cycle five core enzymes one activating enzyme and one mitochondrial ornithine citrulline antiporter with an estimated incidence of 1 8 000 Urea cycle disorders UCDs are inborn errors of metabolism IEMs resulting from defects in any 1 of the six enzymes or 2 transporters involved in the hepatic removal of ammonia from the bloodstream by conversion to urea which is excreted by the kidneys 1 IEMs fall into two very broad categories deficiencies in specific enzymes
There are eight types of urea cycle disorders identified by the lack or malfunction deficiency of certain enzymes and proteins in your metabolism that process urea N acetylglutamate synthase NAGS deficiency Carbamoylphosphate synthetase I CPS1 deficiency Ornithine transcarbamylase OTC deficiency There are also two enzyme transporter deficiencies which are often considered UCDs HHH Syndrome ORNT deficiency CTLN2 Citrullinemia Type II or Citrin deficiency

Patients with a complete enzyme deficiency often present during the first days of life with hyperammonemic coma with about 50 mortality despite early and aggressive treatment Urea cycle disorders UCD are human conditions caused by the dysregulation of nitrogen transfer from ammonia nitrogen into urea The biochemistry and the genetics of these disorders were well elucidated Earlier diagnosis and improved treatments led to an emerging longer lived cohort of patients
Measuring serum ammonia levels may be helpful in monitoring the efficacy of ammonia lowering therapy Elevated levels are also seen in Reye s syndrome and other urea cycle enzyme deficiencies Acute leukemia Bone marrow transplantation Blood transfusion Portal systemic shunts Gastrointestinal bleeding Chronic renal failure Clinical symptoms blood tests to assess ammonia and amino acid levels and genetic testing to identify particular enzyme deficits are frequently used to diagnose urea cycle diseases To stop hyperammonemia related life threatening consequences early identification and management are essential
