SLC22A5 gene

The SLC22A5 gene, also known as cationcarnitine transporter 2 (OCTN2) gene, provides instructions for making a protein that is involved in the transport of organic cations, including carnitine. Carnitine is an essential molecule for the transport of fatty acids into mitochondria, where they are used for energy production. Deficiency in the SLC22A5 gene can lead to a primary carnitine deficiency, a condition characterized by reduced levels of carnitine in the body.

Primary carnitine deficiency can result in a range of health problems, including muscle weakness, heart muscle disease, and liver problems. It may also be associated with other conditions such as Crohn’s disease. Genetic testing for mutations in the SLC22A5 gene can be used to confirm a diagnosis of primary carnitine deficiency.

Information about the SLC22A5 gene and its variants can be found in various scientific databases and resources. The Online Mendelian Inheritance in Man (OMIM) provides comprehensive information on the genetic basis of diseases, including primary carnitine deficiency and related conditions. PubMed is another valuable resource for accessing scientific articles and references related to the SLC22A5 gene.

The Human Gene Mutation Database (HGMD) and the Catalog of Somatic Mutations in Cancer (COSMIC) are databases that contain information on genetic mutations associated with disease. In addition, the Genetic Testing Registry (GTR) provides information on available genetic tests for primary carnitine deficiency and other genetic conditions.

Health Conditions Related to Genetic Changes

Genetic changes in the SLC22A5 gene can lead to various health conditions and diseases. The primary health condition associated with genetic changes in this gene is primary cationic carnitine deficiency (PCCD). PCCD is a rare genetic disorder that affects the transportation of the organic cation carnitine in the body.

Individuals with PCCD have a mutation in the SLC22A5 gene, which encodes a protein called OCTN2. This protein is responsible for the uptake of carnitine into cells. Mutations in the SLC22A5 gene result in a reduced or complete loss of OCTN2 function, leading to a deficiency of carnitine in the body.

Primary cationic carnitine deficiency can manifest in various ways, including muscle weakness, cardiomyopathy, liver dysfunction, and hypoglycemia. It can also cause other health conditions, such as Crohn’s disease and other metabolic disorders.

In order to diagnose primary cationic carnitine deficiency, genetic testing of the SLC22A5 gene is performed. This testing can identify specific genetic changes or variants in the gene that are associated with the disease.

Further scientific resources and information about primary cationic carnitine deficiency and other health conditions related to genetic changes in the SLC22A5 gene can be found in various databases and articles. These resources include the Online Mendelian Inheritance in Man (OMIM) catalog, which provides information on genetic disorders, and PubMed, which contains scientific articles on various health topics.

Additionally, the Filippo foundation provides a registry and additional information on primary cationic carnitine deficiency and related diseases. The registry collects data on individuals with primary carnitine deficiency to further research and understanding of the condition.

Primary carnitine deficiency

Primary carnitine deficiency is a genetic condition caused by mutations in the SLC22A5 gene, also known as the OCTN2 gene. This gene provides instructions for making a protein called the organic cation/carnitine transporter. This protein is responsible for the transport of carnitine into cells.

Carnitine is an amino acid that plays a critical role in the metabolism of fats. It is responsible for transporting fatty acids into the mitochondria, where they can be used as a source of energy. In individuals with primary carnitine deficiency, the transport of carnitine into cells is impaired, leading to a buildup of fatty acids and a deficiency of carnitine in the body.

Primary carnitine deficiency is inherited in an autosomal recessive manner, which means that an individual must inherit two copies of the mutated SLC22A5 gene, one from each parent, in order to develop the condition. People who inherit only one copy of the mutated gene are carriers and do not typically experience any symptoms.

Symptoms of primary carnitine deficiency can vary widely, but may include muscle weakness, low blood sugar, cardiomyopathy (weakening of the heart muscle), and liver dysfunction. If left untreated, the condition can lead to life-threatening complications.

Primary carnitine deficiency can be diagnosed through genetic testing, which can detect mutations in the SLC22A5 gene. Testing may be recommended in individuals with symptoms of the condition, as well as in family members of affected individuals to determine if they are carriers.

Treatment for primary carnitine deficiency involves the supplementation of carnitine. This can help to restore normal carnitine levels and alleviate symptoms. With early diagnosis and appropriate treatment, individuals with primary carnitine deficiency can lead normal, healthy lives.

Crohn’s disease

Crohn’s disease is a chronic inflammatory disease of the digestive tract. It is one of the diseases that can result from changes in the SLC22A5 gene. This gene provides instructions for making a protein called organic cationcarnitine transporter 2 (OCTN2), which is responsible for transporting carnitine into cells.

Many scientific articles listed on the OMIM database and PubMed provide additional information about Crohn’s disease and its relationship to the SLC22A5 gene. The SLC22A5 gene is also known by other names, such as OCTN2 and CACT.

Crohn’s disease is not the only disease associated with changes in the SLC22A5 gene. It is one of several conditions that can result from changes in this gene. Other related conditions include primary carnitine deficiency and sodium-coupled neutral amino acid transporter deficiency.

Genetic testing can be used to identify changes in the SLC22A5 gene and determine if someone is a carrier of these genetic changes. Genetic testing can also provide information about the risk of developing Crohn’s disease or other related conditions.

The Filippo Foundation Gene Therapy Program maintains a registry of genetic changes in the SLC22A5 gene and provides resources for testing and information on related diseases.
