Ornithine translocase deficiency is a rare genetic disorder that affects the transport of ornithine, a key component in the urea cycle. It is typically present at birth and can cause severe symptoms in infants. The condition is caused by mutations in the SLC25A15 gene, which codes for the ornithine translocase protein. In affected individuals, the impaired transport of ornithine leads to a buildup of ammonia and toxic byproducts in the urine.

The symptoms of ornithine translocase deficiency can vary, but usually include developmental delay, high-protein intake intolerance, and impaired urinary concentration. Additional symptoms may include diarrhea, vomiting, and liver dysfunction. In some cases, the condition can also be associated with other genetic diseases.

Diagnosis of ornithine translocase deficiency is typically made through genetic testing, specifically by sequencing the SLC25A15 gene. In some cases, additional tests such as urine ammonia levels and amino acid analysis may be performed to confirm the diagnosis. Treatment for the condition often involves a low-protein diet and medication to manage ammonia levels.

Research on ornithine translocase deficiency is ongoing, with studies focused on understanding the underlying genetic mutations and potential treatment options. The Orphanet consortium provides a comprehensive catalog of information on the condition, including clinical guidelines and advocacy resources. Clinical trials can also be found on clinicaltrialsgov and research articles on PubMed.

Frequency

Ornithine translocase deficiency is a rare genetic disorder that impairs the transport of ornithine, an amino acid, across the inner mitochondrial membrane. This causes the accumulation of ammonia and urea in the urine, leading to symptoms associated with high-protein intake and urea cycle disorders.

The frequency of ornithine translocase deficiency is unknown due to its rarity. However, according to scientific articles and studies, it is estimated to affect approximately 1 in 300,000 to 1 in 500,000 individuals worldwide.

About half of all denied claims that are challenged or appealed ultimately end up being covered – but only when policyholders put in the time and energy to fight the denial, the Los Angeles Times

There is limited information available on the frequency of ornithine translocase deficiency within specific populations or ethnic groups. Further research and testing are needed to obtain more accurate data.

Due to the rarity of ornithine translocase deficiency, there are limited resources and support available for patients and families affected by this condition. However, advocacy groups, such as the Genetic and Rare Diseases Information Center (GARD) and the National Organization for Rare Disorders (NORD), provide information, support, and resources for individuals with rare diseases, including ornithine translocase deficiency.

More research and clinical trials are needed to better understand ornithine translocase deficiency and develop effective treatments. Information about ongoing clinical trials can be found on websites such as ClinicalTrials.gov.

Causes

The main cause of Ornithine Translocase Deficiency (OTCD) is mutations in the SLC25A15 gene, which is responsible for producing a protein called ornithine translocase (ORNT1).

These mutations can impair the transport of ornithine, a molecule involved in the urea cycle, which is responsible for removing ammonia from the body. Without functional ORNT1, ornithine cannot be properly transported into the mitochondria, leading to a buildup of ammonia in the blood and tissues.

OTCD is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the condition. Individuals who have only one mutated copy of the gene are carriers and typically do not show symptoms of the disorder.

OTCD is a rare genetic disorder, with an estimated frequency of 1 in 200,000 to 1 in 800,000 births. It mainly affects infants, but can also manifest in older children and adults.

Learn more about the gene associated with Ornithine translocase deficiency

Ornithine translocase deficiency, also known as Ornitinemia, is a rare genetic condition caused by mutations in the gene ORNT1. ORNT1 is responsible for encoding a protein called ornithine translocase, which plays a crucial role in the transport of ornithine, a key molecule in the urea cycle.

The urea cycle is a metabolic pathway that converts toxic ammonia into urea, which can be safely excreted by the body. Ornithine translocase is involved in transporting ornithine across the inner mitochondrial membrane, allowing it to participate in the urea cycle. Without functional ornithine translocase, the urea cycle is impaired, leading to the accumulation of ammonia in the bloodstream.

Ornithine translocase deficiency follows an autosomal recessive inheritance pattern, meaning that individuals must inherit two defective copies of the ORNT1 gene, one from each parent, to develop the condition. Its frequency is very low, with only a few dozen cases reported in scientific literature.

Patients with Ornithine translocase deficiency may present with symptoms such as delayed development, intellectual disability, seizures, and high-protein levels in the blood. Early diagnosis and intervention are crucial to manage the condition and prevent complications.

Inheritance

Ornithine translocase deficiency, also known as hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome, has an autosomal recessive inheritance pattern. This means that both copies of the gene must be mutated in order for the condition to be present.

The gene associated with this condition is called SLC25A15, which provides instructions for making a protein called ornithine translocase. Mutations in the SLC25A15 gene result in a deficiency of this protein.

Research studies have identified various mutations in the SLC25A15 gene that are associated with ornithine translocase deficiency. These mutations can impair the transport of ornithine across the inner mitochondrial membrane, leading to the accumulation of ornithine in the urine and increased levels of ammonia in the blood.

Several resources, such as PubMed and OMIM, provide additional information on the genetic causes and inheritance patterns of ornithine translocase deficiency, as well as the associated symptoms and clinical features.

Testing for ornithine translocase deficiency is available, and genetic testing can confirm the diagnosis. Early detection and diagnosis of the condition can be beneficial, as it allows for prompt treatment and management.

Given the rarity of ornithine translocase deficiency, there may be limited information and resources available. However, advocacy groups, research centers, and patient support organizations can provide valuable assistance and guidance to both patients and healthcare providers.

One of the genetic conditions cataloged in OMIM is Ornithine Translocase Deficiency, also known as Deficiency of Ornithine Translocase or ORNT1 deficiency. This condition is caused by mutations in the SLC25A15 gene, which encodes for the Ornithine Translocase protein. The impaired functioning of this protein leads to the accumulation of ammonia and urea in the urine, causing high-protein and toxic urine.

ORNT1 deficiency is a rare genetic disorder with an autosomal recessive inheritance pattern. It is characterized by delayed development, intellectual disability, and liver disease. Infants with this condition may present with feeding difficulties, failure to thrive, and abnormal neurologic findings.

Testing for ORNT1 deficiency involves genetic testing to identify mutations in the SLC25A15 gene. This can be done through a blood or saliva sample. Genetic counseling is recommended for individuals or families considering testing for this condition.

There is currently no cure for ORNT1 deficiency, and treatment focuses on managing the symptoms. Guidelines for the management of the condition include a low-protein diet and medications to reduce ammonia levels. Regular monitoring of ammonia and urea levels in the blood is necessary to prevent complications.
