FUNÇÃO

One of the enzymes of the urea cycle, the metabolic pathway transforming neurotoxic amonia produced by protein catabolism into inocuous urea in the liver of ureotelic animals. Catalyzes the formation of arginosuccinate from aspartate, citrulline and ATP and together with ASL it is responsible for the biosynthesis of arginine in most body tissues

VIAS BIOLÓGICAS (1)
Urea cycle
MECANISMO DE DOENÇA

Citrullinemia 1

The classic form of citrullinemia, an autosomal recessive disease characterized primarily by elevated serum and urine citrulline levels. Ammonia intoxication is another manifestation. It is a disorder of the urea cycle, usually manifesting in the first few days of life. Affected infants appear normal at birth, but as ammonia builds up in the body they present symptoms such as lethargy, poor feeding, vomiting, seizures and loss of consciousness. Less commonly, a milder form can develop later in childhood or adulthood.

[A 71-year-old woman with adult-onset type II citrullinemia, initially presenting with normal blood ammonia levels].

Rinsho shinkeigaku = Clinical neurology2026 Jan 22

The patient, a 71-year-old woman, was admitted for a generalized tonic-clonic seizure. Initial investigations, including plasma ammonia, were normal, and she was treated for status epilepticus. Consciousness recovered to Japan Coma Scale (JCS) 0, but on day 4 her alertness declined; plasma ammonia exceeded 500 ‍μg/dl, and a dietary preference for beans became apparent. Plasma citrulline was markedly elevated, and genetic analysis confirmed adult-onset type II citrullinemia (CTLN2). A low-carbohydrate, high-fat diet enriched with medium-chain triglyceride oil was initiated, yet higher order cognitive deficits persisted. Because CTLN2 exhibits diurnal fluctuations in blood ammonia, in cases of unexplained impaired consciousness it is essential to ask about food preferences and to measure plasma ammonia repeatedly to enable timely diagnosis and treatment.

Impact of long-term nitrogen scavenger therapy on clinical outcome in individuals with urea cycle disorders.

Scientific reports2026 Mar 18

Principles of long-term medical management in individuals with urea cycle disorders (UCDs) encompass (1) a low protein diet, (2) supplementation of arginine and/or citrulline along with essential amino acids, nutrients, vitamins and trace elements, and (3) use of nitrogen scavenging agents to reduce recurrent hyperammonemic events (HAEs). These principles aim at providing metabolic stability, elimimation of chronic complications, and achievement of normal development as well as growth. A retrospective comparative analysis was performed by studying 138 individuals with male ornithine transcarbamylase deficiency (mOTC-D), citrullinemia type 1 (CTLN1) and argininosuccinic aciduria (ASA) based on in vitro residual enzymatic activity for severity-adjustment. Results show that individuals with mOTC-D, CTLN1 and ASA are at risk of progressive linear growth impairment, recurrent annual HAEs and an unfavorable neurocognitive outcome despite being under long-term nitrogen scavenging pharmacotherapy. No overall superiority among existing nitrogen scavenging agents with regard to the individual's metabolic stability, linear growth impairment and poor neurocognitive outcome was observed. Novel therapeutic strategies are urgently needed to ultimately improve health outcomes in individuals with UCDs in order to sufficiently meet guideline-specific goals.

Looking Beyond Severe Hypertriglyceridemia when Diagnosing Adult-Onset Citrullinemia Type II.

European journal of case reports in internal medicine2026

Adult-onset citrullinemia type II (CTLN2) is a rare autosomal recessive urea cycle disorder caused by mutations in the solute carrier family 25 member 13 (SLC25A13) gene, which encodes citrin-a mitochondrial transporter involved in the malate-aspartate shuttle. In adults, CTLN2 may present atypically as isolated hypertriglyceridemia, often misattributed to secondary dyslipidaemia. A 30-year-old Vietnamese male with longstanding severe hypertriglyceridemia, first identified at age 13, was referred after an episode of acute pancreatitis at age 28. At presentation, plasma triglyceride levels reached 34.61 mmol/l. Secondary causes were excluded. Genetic testing via next-generation sequencing revealed compound heterozygous SLC25A13 mutations: c.2T>C and c.1638_1660dup, resulting in p.Met1Thr and p.Ala554GlyfsTer17, confirming the diagnosis of CTLN2. Initiation of a low-carbohydrate, high-protein, low-fat diet combined with fenofibrate (145 mg/day) led to a rapid reduction in triglyceride levels, normalizing within two weeks and remaining stable over three months. The treatment was well tolerated, with no reported adverse effects. CTLN2 should be considered in young adults with persistent, unexplained, and severe hypertriglyceridemia. Dietary modification constitutes the cornerstone of management, with fibrates playing a supportive role. Persistent, unexplained, and severe hypertriglyceridemia in young adults should prompt consideration of inherited metabolic disorders, including adult-onset citrullinemia type II (CTLN2).Genetic testing to detect compound heterozygous or homozygous SLC25A13 variants is essential for definitive diagnosis of CTLN2.In CTLN2, dietary management with a low-carbohydrate, high-protein, low-fat represents the cornerstone, with fibrates serving as adjunctive lipid-lowering therapy.

99 Chinese ASS1 carriers: Genetics, metabolism, and citrulline levels.

Clinica chimica acta; international journal of clinical chemistry2026 Jan 01

Citrullinemia type I is an autosomal recessive disorder caused by mutations in the ASS1 gene, whereas ASS1 mutation carriers typically have a mutation in only one allele. While carriers are usually asymptomatic, they often show mildly elevated plasma citrulline levels. This study aims to investigate the relationship between the genetic background of ASS1 carriers and plasma citrulline levels, as well as the potential mechanisms behind the elevation. The study analyzed 99 ASS1 mutation carriers identified through neonatal screening. Clinical and genetic data were collected, including plasma citrulline levels at initial and follow-up screenings. This is the first large-scale analysis of the relationship between ASS1 mutations and plasma citrulline levels in carriers. Twenty-eight distinct variants were identified, with c.1087C > T (p.R363W) being the most common. Plasma citrulline levels in carriers were elevated, showing a rising then falling pattern over first six months, with a peak of 65.84 µmol/L during re-screening. Levels gradually declined thereafter and stabilized around 49.92 μmol/L, but consistently remained above the normal reference range. A citrulline threshold of 62.04 µmol/L effectively differentiated ASS1 carriers from Citrullinemia type I patients (AUC = 0.984). Elevated plasma citrulline levels are often seen in mutations affecting the monomer-monomer interface, though other mechanisms may be involved. This study identified 62.04 µmol/L as a reference threshold at the time of newborn screening to distinguish ASS1 carriers from Citrullinemia type I patients, observed a dynamic pattern of citrulline levels over the first six months in carriers, and suggested a potential role for dominant-negative effects in the underlying mechanism.
