Triosephosphate isomerase deficiency is a rare genetic condition that is associated with a mutation in the gene for the enzyme triosephosphate isomerase. This condition typically causes a range of symptoms, including muscle weakness, brain abnormalities, and heart problems. It is inherited in an autosomal recessive manner, meaning that individuals must inherit two copies of the mutated gene to develop the condition.

Triosephosphate isomerase deficiency is a very rare condition, with a frequency of less than 1 in 10 million individuals. It is named after the triosephosphate isomerase enzyme, which is responsible for converting a molecule called dihydroxyacetone phosphate into glyceraldehyde 3-phosphate. Without this enzyme, certain metabolic processes are disrupted and can lead to the symptoms associated with the condition.

Patients with triosephosphate isomerase deficiency may experience muscle weakness and atrophy, especially in the limbs, leading to difficulty with movement. They may also have intellectual and developmental delays, seizures, and heart abnormalities. In severe cases, the condition can lead to respiratory failure and early death, often in childhood.

Triosephosphate isomerase deficiency was first described by Torres-Larios and colleagues in 1993, and there have been several other scientific articles published since then about this condition. Additional information can be found on various scientific resources, such as the OMIM database, PubMed, and the Genetic Testing Registry. Patient advocacy organizations, such as the Gomez-Puyou Center for Advocacy and Kamoun’s Heart, provide support, information, and resources for individuals and families affected by triosephosphate isomerase deficiency.

In summary, triosephosphate isomerase deficiency is a rare genetic condition that causes muscle weakness, brain abnormalities, and heart problems. It is associated with a mutation in the gene for the triosephosphate isomerase enzyme, which disrupts metabolic processes in the body. The condition is inherited in an autosomal recessive manner and can lead to severe symptoms and early death. More information and support can be found through various scientific and advocacy resources.

Frequency

Triosephosphate isomerase deficiency is a rare genetic condition caused by a mutation in the triosephosphate isomerase (TPI) gene. The frequency of this condition is relatively low, with only a few reported cases worldwide.

Just under half – 49% – of Americans get their health insurance through their employer, according to the Henry J. Kaiser Family Foundation. Another 19% of Americans are insured under Medicaid, 14% under Medicare, seven% under non-group plans and two% under other public insurers, while nine% of U.S. citizens remain uninsured.

This autosomal recessive inherited disease affects the enzyme triosephosphate isomerase, which plays a crucial role in glycolysis. Without functional triosephosphate isomerase, the body experiences a buildup of toxic intermediates, leading to the various symptoms associated with this condition.

Patients with triosephosphate isomerase deficiency typically present with symptoms involving the brain, heart, skeletal muscle, and diaphragm. These symptoms can range from mild to severe and may include developmental delay, intellectual disability, muscle weakness, cardiomyopathy, and respiratory problems.

According to the OMIM catalog, the gene associated with triosephosphate isomerase deficiency is TPI1. Additional information about this condition and the gene can be found on the OMIM website and other genetic resources.

There are currently no known advocacy organizations specifically dedicated to triosephosphate isomerase deficiency. However, scientific articles and case reports on this rare disease can be found on PubMed, a database of biomedical literature.

In conclusion, triosephosphate isomerase deficiency is a rare genetic condition that causes a variety of symptoms affecting multiple organ systems. More research and testing are necessary to learn about the frequency and underlying causes of this condition.

Causes

Triosephosphate isomerase deficiency is a rare autosomal recessive genetic condition caused by mutations in the TPI1 gene. This gene provides instructions for making the enzyme triosephosphate isomerase, which is involved in the breakdown of glucose.

Individuals with triosephosphate isomerase deficiency have a reduced or absent amount of this enzyme, which leads to a buildup of toxic substances in the body. This accumulation affects multiple organs and tissues, including the brain, heart, muscles, and diaphragm.

The exact causes of these gene mutations are not yet fully understood. However, researchers have identified more than 50 different mutations in the TPI1 gene that can cause triosephosphate isomerase deficiency. These mutations can occur spontaneously or be inherited from affected parents.

The condition is typically associated with rare and severe neurological symptoms, including intellectual disability, muscle weakness, and delayed development. It can also lead to other complications such as cardiomyopathy and respiratory problems.

Triosephosphate isomerase deficiency is a very rare condition, and its frequency in the general population is not well defined. However, it is more common in specific populations, such as those with consanguineous marriages.

Diagnosis of triosephosphate isomerase deficiency involves genetic testing to identify mutations in the TPI1 gene. Additional testing may be done to evaluate the levels of triosephosphate isomerase in the blood or measure enzyme activity.

There are currently no specific treatments for triosephosphate isomerase deficiency. However, supportive care can help manage the symptoms and improve the quality of life for affected individuals. Treatment may involve physical therapy, respiratory support, and management of complications such as cardiac abnormalities.

Advocacy organizations and support resources are available to help patients and their families learn more about this rare condition. Scientific articles, patient advocacy websites, and genetic resources provide additional information on triosephosphate isomerase deficiency and support for affected individuals and their families.
