Citrullinemiais an autosomal recessiveurea cycle disorderthat causes ammoniaand other toxic substances to accumulate in the blood. [1] Two forms of citrullinemia have been described, both having different signs and symptoms, and are caused by mutations in different genes. Introduction: Citrullinemia type 1 (CTLN1) is a urea cycle disorder caused by defective argininosuccinate synthetase leading to impaired ammonia elimination. Urea cycle disorders are typically
Citrullinemia may be thought in the differential diagnosis of inborn errors of metabolism accompanied by hiccups. referenCes 1. Wayenberg JL, Vermeylen D, Gerlo E, Pardou A.

Citrullinemia is an autosomal recessive disorder that causes ammonia to accumulate in the blood. This belongs to a genetic disease called urea cycle defect. Two forms of citrullinemia have been described. Type 1 citrullinemia Type 1 is the most common disorder presenting in the first few days of life [1,2]. Affected infants typically
Introduction. Type II citrullinemia is an autosomal recessive disorder caused by mutations in the SLC25A13 gene, characterized by episodes of hyperammonaemic encephalopathy. 1 The adult onset form presents as a neurobehavioral syndrome (aggression, irritability, hyperactivity, disorientation and coma) with seizures presenting in less than 10% of patients which can be life threatening. 2
Citrullinemia (OMIM 215700) is an autosomal recessive condition caused by mutations in the gene encoding argininosuccinate synthetase, which also forms part of the urea cycle.

Citrullinemia cases have been reported in Japan that show a particular form of citrullinemia in adults that had been previously undiscovered and untreated; one case was discovered as late as age 48 years. [5, 6] Some patients were developmentally delayed from childhood, whereas others were asymptomatic until onset.
Citrullinemia is an autosomal recessively inherited disorder of urea cycle metabolism and ammonia detoxification (see this term) characterized by elevated concentrations of serum citrulline and ammonia. The disease presents with a large range of manifestations including neonatal hyperammonemic encephalopathy with lethargy, seizures and coma
Discussion. Citrullinemia represents the fourth most common anomaly of the urea metabolic pathway. However, its prevalence remains unspecified in the literature, which only suggests that male and female cases seem to occur equally ().Citrullinemia is due to a deficiency in AAS, which McMurray and coauthors initially described in 1962.At least three phenotypes are clinically recognized: the Adult-onset type II citrullinemia (CTLN2) is characterized by a liver-specific deficiency of argininosuccinate synthetase (ASS) protein. We have recently identified the gene responsible for CTLN2, viz., SLC25A13, which encodes a calcium-binding mitochondrial carrier protein, designated citrin, and found five mutations of the SLC25A13 gene in CTLN2 patients.
Type I citrullinemia shows kinetically abnormal ASS in the liver, kidney, and cultured fibroblasts. In type II, low ASS is found in the liver but not in kidney or cultured skin
