 Citrullinemia
The symptoms of citrullinemia are caused by the accumulation of ammonia in the blood.
The estimated frequency of citrullinemia is one in 250,000 births.

 DBGET Result: OMIM 215700
They concluded that in type II citrullinemia, the decrease in the enzyme protein is due either to increased degradation of the enzyme or to decreased or inhibited translation in the liver.
Patients with citrullinemia tend to have higher plasma ammonia concentrations for a given plasma glutamine concentration compared to those with OTC deficiency, and there was not a simple linear relationship between glutamine and ammonia in either condition.
The mutations gly390 to arg (G390R; 603470.0009), IVS13+5G-A (603470.0017), and arg108 to leu (R108L; 603470.0014) were associated with classic citrullinemia, whereas the mutations trp179 to arg (W179R; 603470.0015) and gly362 to val (G362V; 603470.0016) were detected on alleles of mildly affected patients.

Thus, age of onset is as unpredictable in citrullinemia as in ornithine transcarbamylase (OTC) deficiency.
Citrullinemia is inherited as an autosomal recessive trait; thus, both genders are equally affected.
Both parents of an affected infant are assumed to be obligate heterozygotes because citrullinemia is an autosomal recessive trait; therefore, the recurrence rate in every subsequent pregnancy is 1 in 4, or 25%.

Citrullinemia type 1: A group of diseases related to a deficiency of the enzyme ARGININOSUCCINATE SYNTHASE which causes an elevation of serum levels of CITRULLINE.
Citrullinemia type 1 is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).

The authors concluded that the elucidation of the structure of the human ASS gene made it possible to use intronic primers for molecular analysis of patients with mild disease and the classic form, and provided another option for prenatal diagnostics in affected families with the severe type.
Although undetectable ASS protein is the criterion of type III citrullinemia, a very low amount of ASS crossreacting material was detected in the liver of a patient with this form of the disease.
