The SLC25A15 gene, also known as the ornt1 gene, is a gene that is responsible for encoding a protein called ornithine translocase. This protein plays a crucial role in the transport of ornithine, an amino acid, across the mitochondrial membrane. Mutations or changes in the SLC25A15 gene can lead to a deficiency in ornithine translocase, which can cause a rare genetic disorder known as hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome.

HHH syndrome is characterized by increased levels of ornithine, ammonia, and homocitrulline in the blood and urine. This can result in a variety of symptoms, including impaired liver function, neurological abnormalities, developmental delays, and intellectual disability. Diagnosis of HHH syndrome is typically done through genetic testing, which can identify mutations in the SLC25A15 gene.

References to the SLC25A15 gene can be found in scientific databases such as PubMed, which is a vast resource for articles related to genetic disorders. Additional information on HHH syndrome and testing for SLC25A15 gene mutations can be found in the Online Mendelian Inheritance in Man (OMIM) database.

Testing for mutations in the SLC25A15 gene can be done through various genetic testing companies and laboratories, many of which are listed in the OMIM database. The Genetic Testing Registry (GTR) is another useful resource for finding information on genetic testing options for HHH syndrome and other related disorders.

In conclusion, the SLC25A15 gene, also known as the ornt1 gene, plays a critical role in the transport of ornithine across the mitochondrial membrane. Mutations in this gene can lead to a deficiency in ornithine translocase and the development of HHH syndrome. Genetic testing can be done to identify these mutations, and there are various resources available for information and testing options for HHH syndrome and related disorders.

The SLC25A15 gene, also known as the ornithine translocase deficiency gene or ORNT1 gene, is related to various health conditions when genetic changes occur. These changes can result in a deficiency in the function of the ORNT1 protein, leading to different conditions.

For both workers and companies, employer-sponsored health insurance is costly. For 2018, employers paid an average of $10,000 per employee to cover 70% of the cost of health insurance, leaving workers with a price tag of about $4,200 for the remaining 30% of the expense, CNBC

Some of the health conditions associated with changes in the SLC25A15 gene include:

  • Citrullinemia type II: This is a rare genetic disorder that affects the body’s ability to break down and eliminate waste products, leading to a buildup of toxic substances in the blood.
  • Hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome: This is a metabolic disorder characterized by high levels of ornithine, ammonia, and homocitrulline in the blood.
  • Hepatic encephalopathy: This is a condition that occurs when there is a build-up of toxic substances in the brain due to liver dysfunction.
  • Other conditions: Genetic changes in the SLC25A15 gene may also be related to other health conditions that are less commonly reported.

If you or someone you know has a family history of these health conditions or shows symptoms related to them, it is recommended to consult with a healthcare professional. Genetic testing can help identify the specific variant in the SLC25A15 gene and provide additional information for diagnosis and management.

There are several databases and resources available to gather information on genetic changes in the SLC25A15 gene and related diseases. Some of the most common ones include:

  • Genetic Testing Registry (GTR)
  • Online Mendelian Inheritance in Man (OMIM)
  • PubMed

These resources provide scientific articles, genetic testing information, and other valuable data for researchers, healthcare professionals, and individuals seeking information on the SLC25A15 gene and associated conditions.

It is important to note that genetic changes in the SLC25A15 gene are relatively rare, and most individuals with this gene variant do not develop the related health conditions. However, understanding the genetic basis of these conditions can help with early diagnosis, management, and potential treatments.

Common Health Conditions Related to Genetic Changes in the SLC25A15 Gene
Condition Description
Citrullinemia type II A rare genetic disorder leading to a buildup of toxic substances in the blood.
Hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome A metabolic disorder characterized by high levels of ornithine, ammonia, and homocitrulline in the blood.

Ornithine translocase deficiency

Ornithine translocase deficiency, also known as Ornt1 deficiency or Hyperornithinemia-Hyperammonemia-Homocitrullinuria (HHH) syndrome, is a rare genetic condition that affects the SLC25A15 gene. It is named after its discoverers, Andrade et al., who first described the syndrome in 1981.

In Ornithine translocase deficiency, there is a mutation or change in the SLC25A15 gene, which leads to the production of a non-functional or reduced-functioning ornithine translocase protein. This protein is responsible for transporting ornithine, an amino acid, across the inner mitochondrial membrane. Without functional ornithine translocase, ornithine accumulates in the mitochondria, leading to a toxic build-up of ammonia and homocitrulline in the blood and tissues.

Ornithine translocase deficiency is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the non-functioning gene (one from each parent) to develop the condition. It is estimated to occur in approximately 1 in 800,000 to 1,000,000 individuals.

Clinical presentation of Ornithine translocase deficiency can vary widely, ranging from mild to severe. Symptoms typically appear in infancy or early childhood and may include episodic confusion, intellectual disability, liver dysfunction, seizures, developmental delay, and neurological problems.

Diagnosis of Ornithine translocase deficiency is typically confirmed through genetic testing, which can identify mutations in the SLC25A15 gene. Other laboratory tests for elevated levels of ornithine, ammonia, and homocitrulline in the blood and urine can also aid in the diagnosis. Additional testing may be necessary to rule out other related conditions.

There is currently no cure for Ornithine translocase deficiency, and treatment is mostly focused on managing symptoms and preventing complications. This may include a specialized diet low in protein and ammonia, medications to reduce ammonia levels, and supportive care for specific symptoms.

Support and resources for individuals and families affected by Ornithine translocase deficiency can be found through various organizations, such as the Genetic and Rare Diseases Information Center (GARD), the Online Mendelian Inheritance in Man (OMIM) database, and the HHH Syndrome Scientific Registry. These resources provide information on genetic counseling, clinical trials, support groups, and research advances.
