Transcobalamin deficiency is a rare genetic condition associated with the failure to transport cobalamin, also known as vitamin B12, within the body’s cells. This deficiency leads to a wide range of cellular and neurological symptoms, causing significant morbidity and mortality in affected individuals.
The inheritance pattern of transcobalamin deficiency is autosomal recessive, meaning that an individual must inherit two copies of the defective gene, one from each parent, in order to develop the condition. The genetic basis of this disorder has been extensively studied, with several genes identified and cataloged in resources such as OMIM and PubMed.
Clinical trials.gov is a valuable resource for additional information on ongoing studies and testing for transcobalamin deficiency. Advocacy groups and research centers also offer support and resources for patients and families affected by this rare condition. Scientific articles, patient stories, and other clinical trials.gov provide a wealth of knowledge on the symptoms, causes, and testing of transcobalamin deficiency.
Frequency
Transcobalamin deficiency is a rare genetic condition that is associated with neurological diseases. The frequency of this condition is not well known, but it is thought to be a rare disorder.
There are only a few articles and scientific studies that have been published on this condition, with limited information available. However, research is ongoing to better understand the frequency and causes of this genetic deficiency.
Patients with transcobalamin deficiency may develop clinical symptoms such as neurological abnormalities and failure to thrive. Genetic testing can be performed to confirm the diagnosis.
As of August 2020, the most expensive drug in America is Myalept, a drug used to treat leptin deficiency. A month’s worse of this drug costs $71, 306 per month, according to research from GoodRx. Myalept is known as an “orphan drug” because it’s intended to treat a rare disease.
Currently, there are no compounds or specific treatments available for transcobalamin deficiency. Supportive care and management of the symptoms are the main approaches for patients with this condition.
For more information on testing, resources, and advocacy support for transcobalamin deficiency, clinicaltrialsgov and OMIM are valuable resources. Additional information can also be found at genetic testing centers and research catalogs.

Researchers are continuing to study the genetic inheritance and cellular transport of transcobalamin. More studies and scientific articles are needed to support the understanding of this rare genetic condition.
In summary, transcobalamin deficiency is a rare genetic disorder associated with neurological diseases. Further research and genetic testing resources are needed to learn more about the frequency and causes of this condition.
Causes
Transcobalamin deficiency is a rare genetic condition that affects the transport of vitamin B12 in the body. It is caused by mutations in the TCN2 gene, which provides instructions for making a protein called transcobalamin II. Transcobalamin II is responsible for binding to vitamin B12 and facilitating its transport into cells. Mutations in the TCN2 gene can lead to a decrease or complete absence of functional transcobalamin II, resulting in a deficiency of vitamin B12 in the body.
Inheritance of transcobalamin deficiency follows an autosomal recessive pattern, which means that both copies of the TCN2 gene must have mutations in order for the condition to develop. Individuals who inherit only one mutated TCN2 gene are carriers of the condition and do not typically experience symptoms.
There are several names associated with transcobalamin deficiency, including transcobalamin II deficiency, transcobalamin II deficiency, and transcobalamin (TC) deficiency.
Genetic testing can be used to diagnose transcobalamin deficiency and identify specific mutations in the TCN2 gene. This testing is typically done when there is a clinical suspicion of the condition, such as neurological symptoms or a family history of the condition.
Research studies and clinical trials are currently being conducted to learn more about the causes and frequency of transcobalamin deficiency, as well as potential treatment options. Additional information about these studies can be found on websites such as PubMed, OMIM, and ClinicalTrials.gov.
Patient advocacy groups and scientific research centers may also provide resources and support for individuals with transcobalamin deficiency and their families. These resources can include educational articles, genetic counseling, and information on clinical trials and research.
Learn more about the gene associated with Transcobalamin deficiency
Transcobalamin deficiency is a rare condition that affects the body’s ability to transport vitamin B12 from the digestive system to the cells. It is caused by a mutation in the gene responsible for producing the protein transcobalamin II, which is essential for the transport of vitamin B12.
Research has shown that Transcobalamin deficiency follows an autosomal recessive inheritance pattern, meaning that both copies of the gene must be mutated in order for the condition to develop. The gene associated with this deficiency is known as the TCN2 gene.
Scientists have conducted studies to understand the role of the TCN2 gene and its associated protein transcobalamin II in the transport of vitamin B12. These studies have helped identify the specific genetic mutations that can result in Transcobalamin deficiency.
Additional information about the TCN2 gene and Transcobalamin deficiency can be found in scientific publications, such as the OMIM database and PubMed. ClinicalTrials.gov also provides information on ongoing research studies and clinical trials related to Transcobalamin deficiency.
For patients and families affected by Transcobalamin deficiency, there are advocacy groups and support organizations that provide resources and information. These groups can help individuals better understand their condition, find support networks, and learn about the latest research and treatment options.
It is important for individuals with Transcobalamin deficiency to undergo genetic testing to confirm the diagnosis and identify specific mutations in the TCN2 gene. This information can help guide treatment decisions and management of the condition.
Overall, learning more about the TCN2 gene and its role in Transcobalamin deficiency can provide valuable insights into the causes, inheritance patterns, and potential treatment approaches for this rare neurological disorder.
Inheritance
Transcobalamin deficiency is a rare genetic condition that affects the cellular transport of cobalamin (vitamin B12). The condition is associated with mutations in the gene called TCN2, which provides instructions for making a protein known as transcobalamin II. This protein plays a crucial role in the transport of cobalamin within the body’s cells.
Inherited in an autosomal recessive manner, individuals with transcobalamin deficiency inherit two copies of the mutated gene – one from each parent. If both parents carry one copy of the mutated gene, there is a 25% chance for each child to develop the condition.
Due to the rarity of this condition, more research is needed to fully understand the genetic causes and inheritance patterns of transcobalamin deficiency. Genetic testing can provide additional information about the specific gene mutations associated with the condition and can help in the diagnosis and genetic counseling of affected individuals and their families.
For further information about the inheritance and associated genetic causes of transcobalamin deficiency, you may refer to scientific articles and databases such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources provide a catalog of research studies and articles related to the condition, including information on genes, clinical trials, and other rare diseases associated with neurological and cellular transport failure.
If you or a patient you know has been diagnosed with transcobalamin deficiency, it is recommended to seek support from patient advocacy groups and centers specializing in rare diseases.
