Thrombotic Thrombocytopenic Purpura (TTP) is a rare genetic disorder that affects the normal functioning of the blood clotting process. It is characterized by the formation of small blood clots throughout the body, leading to a decrease in platelet levels, known as thrombocytopenic purpura.

This condition is caused by mutations in the ADAMTS13 gene, which is responsible for producing an enzyme that helps regulate blood clotting. The decrease in ADAMTS13 activity leads to an abnormal buildup of large Von Willebrand factor multimers, resulting in the formation of blood clots.

Research and clinical studies have provided valuable information about TTP and its associated genetic factors. The National Institutes of Health’s PubMed and ClinicalTrials.gov databases contain numerous articles and ongoing clinical trials that explore the causes, inheritance patterns, and potential treatments for TTP.

Although TTP can be inherited, it can also occur sporadically and is not limited to any specific population or age group. The disease can be triggered by various factors, including pregnancy, infections, medications, and other underlying autoimmune disorders. However, the exact mechanisms that lead to the development of TTP in these cases are still being studied.

The Thrombotic Thrombocytopenic Purpura Genetic Testing Center (OMIM) provides additional resources and information about the disease, including genetic testing options, associated genes, and inheritance patterns. Advocacy groups and support centers are also available to provide assistance and resources for individuals and families affected by this rare condition.

With more scientific research and clinical studies, we continue to learn about the genetic and molecular basis of thrombotic thrombocytopenic purpura. By understanding the underlying genetic causes and associated factors in the clotting process, we can develop improved diagnostic tools, treatments, and management strategies to support patients with TTP.

Pre-tax flexible spending accounts (FSAs) are often touted as the answer to high out-of-pocket medical costs, but many FSAs have “use it or lose it” rules. FSA holders lose $50 to $100 per year on average, CBS News reported, but since you’re allowed to contribute up to $2,650, you could risk losing thousands of dollars if you don’t spend your FSA money in time.

In conclusion, thrombotic thrombocytopenic purpura is a rare genetic condition characterized by the formation of blood clots and a decrease in platelet levels. Genetic mutations in the ADAMTS13 gene play a significant role in the development of this condition. Ongoing research, clinical trials, and resources are available to learn more about the disease, support affected individuals, and advance treatment options.

Frequency

Thrombotic thrombocytopenic purpura (TTP) is a rare disease, with an estimated frequency of 3-7 cases per million people per year in the general population. However, the exact frequency is difficult to determine due to the rarity of the condition and limited research.

In pregnancy, the frequency of TTP is higher, affecting approximately 1 in 25,000 pregnancies. Pregnancy-associated TTP typically occurs in the third trimester or early postpartum period.

Genetic inheritance is associated with a rare form of TTP, known as congenital TTP. Mutations in the ADAMTS13 gene, which encodes a protein that regulates the function of platelets, are responsible for this genetic form of the disease. Inherited TTP is estimated to occur in approximately 1 in 1 million people.

Additional testing for ADAMTS13 activity and genetic analysis may be required to confirm the diagnosis of TTP and determine the underlying cause of thrombocytopenia.

Scientific articles and research studies on TTP can be found on PubMed, clinical trial information can be found on ClinicalTrials.gov, and genetic information can be found on OMIM.

Information and resources about TTP, patient advocacy, and support can also be obtained from TTP-specific organizations and centers specializing in the treatment of blood clotting diseases.

Causes

Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder characterized by abnormalities in the clotting process. It is primarily caused by a deficiency of a protein called ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13).

ADAMTS13 plays a crucial role in controlling the activity of von Willebrand factor (vWF), a protein that is involved in the clotting process. In TTP, the deficiency of ADAMTS13 leads to an abnormal accumulation of vWF in blood vessels, which causes the formation of small blood clots throughout the body.

There are two main factors associated with the development of TTP: genetic and acquired factors.

  • Genetic factors: Some individuals with TTP have a genetic mutation in the ADAMTS13 gene, which leads to a lifelong deficiency of the protein. This genetic form of TTP is rare and often inherited in an autosomal recessive manner.
  • Acquired factors: Most cases of TTP are acquired, meaning they are not caused by inherited genetic mutations. Acquired TTP can be triggered by various factors, including pregnancy, infections, autoimmune diseases, certain medications, and other underlying health conditions.

It is important to note that TTP is a complex disease with multiple causes and risk factors. It is crucial to consult with a healthcare professional to determine the specific cause and appropriate management of TTP in each individual case.

Learn more about the gene associated with Thrombotic thrombocytopenic purpura

Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder that causes blood clots to form throughout the body. It is associated with a gene called ADAMTS13, which codes for a protein that plays a crucial role in regulating blood clotting.

The ADAMTS13 gene is located on chromosome 9 and has been found to be responsible for the production of the ADAMTS13 protein. This protein specifically works on breaking down von Willebrand factor (vWF) in the blood, which is important for preventing excessive blood clot formation.

In patients with TTP, the ADAMTS13 gene is either mutated or inactive, leading to a deficiency in the ADAMTS13 protein. Without this protein, vWF is not properly broken down, causing platelets to stick together and form blood clots. These clots can block blood flow to various organs, leading to the symptoms of TTP.

Research has shown that mutations in the ADAMTS13 gene are the primary cause of congenital TTP, a form of the disease that is present from birth. In acquired TTP, the gene may not be mutated, but it can still be inactive due to autoimmune responses or other factors.

Testing for genetic mutations in the ADAMTS13 gene can help confirm a diagnosis of TTP and provide more information about the specific genetic cause of the condition in a patient. This information can be useful for understanding the inheritance pattern, counseling patients about the risk of passing the disease to their children, and developing targeted therapies.

Inheritance

Thrombotic thrombocytopenic purpura (TTP) can be associated with both genetic and acquired causes. In about 10% of cases, TTP is caused by a genetic mutation in the ADAMTS13 gene, which is responsible for regulating the activity of a protein involved in clotting. This genetic form of TTP is inherited in an autosomal recessive manner, meaning that an affected individual must inherit two copies of the mutated gene, one from each parent, to develop the disease.

During pregnancy, TTP can also be triggered by the presence of additional factors in the body. These factors, along with genetic causes, can lead to a decrease in the activity of ADAMTS13 and an increased risk of blood clots forming in smaller blood vessels.

Research studies and scientific articles have provided valuable information about the inheritance and genetic causes of TTP. Genetic testing can be performed to identify mutations in the ADAMTS13 gene, which may help in diagnosing the disease and determining the risk of developing TTP in other family members who may be carriers of the genetic mutation.

While TTP is a rare condition, it is important for patients and their families to have access to resources for support and advocacy. Organizations such as the Thrombotic Thrombocytopenic Purpura Research and Support Center provide information, resources, and clinical trials for patients and their families to learn more about the disease.
