Timothy syndrome is a rare genetic disorder that causes certain heart conditions and is associated with altered regulation of the heart’s electrical system. It is named after Timothy, the first patient diagnosed with this syndrome. The condition is caused by mutations in the CACNA1C gene, which is responsible for the production of a certain type of calcium channel protein in the heart.

Clinical studies have shown that Timothy syndrome is associated with a higher frequency of certain heart disorders, including a longer QT interval and a higher risk of sudden cardiac death. The syndrome has been documented in several scientific articles and is listed in the Online Mendelian Inheritance in Man (OMIM) catalog.

Currently, there is no cure for Timothy syndrome. However, there are ongoing research and clinical trials conducted to learn more about the causes and treatment options for this condition. Additional information about these studies can be found on the ClinicalTrials.gov and PubMed websites, as well as through various patient advocacy and support resources.

Parents of children with Timothy syndrome can seek support and learn more about the condition from organizations such as the Timothy Syndrome Alliance and the CACNA1C-related disorders advocacy and research center. These resources provide information and support to families affected by the syndrome.

Frequency

Timothy syndrome is a rare disorder caused by mutations in the CACNA1C gene. This condition affects the heart’s electrical system and can lead to life-threatening arrhythmias, heart defects, and other associated symptoms. The prevalence of Timothy syndrome is estimated to be about 1 in every 1 million people.

Research on Timothy syndrome and its associated genes has been supported by resources such as the National Institutes of Health (NIH), the National Center for Advancing Translational Sciences (NCATS), and the Timothy Syndrome Alliance, an advocacy and support organization for individuals and families affected by the condition.

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.

In addition to Timothy syndrome, mutations in the CACNA1C gene can also cause other rare genetic diseases. These include long QT syndrome and sudden unexplained death in infancy (SUDI). The frequency of these conditions is also very low.

Further information on the frequency and causes of Timothy syndrome can be found in scientific articles and databases like PubMed, OMIM, and ClinicalTrials.gov. These resources provide valuable research and clinical information about the condition and its associated genes.

Genetic testing is often recommended for individuals with symptoms that suggest a potential diagnosis of Timothy syndrome or related conditions. Testing for mutations in the CACNA1C gene can help confirm a diagnosis and guide treatment decisions.

Causes

Timothy syndrome is a rare genetic disorder that is caused by mutations in the CACNA1C gene, which plays a critical role in the regulation of electrical activity in the heart. These mutations result in altered calcium channel function, leading to abnormal electrical signals in the heart.

The CACNA1C gene is also associated with other cardiac disorders, such as long QT syndrome and Brugada syndrome. Mutations in this gene can cause a wide range of symptoms, including prolonged QT intervals, ventricular arrhythmias, and congenital heart defects.

Timothy syndrome is inherited in an autosomal dominant manner, which means that a person only needs to inherit one copy of the mutated gene from one parent to develop the condition. However, in some cases, Timothy syndrome can also occur as a result of de novo mutations, which means that the mutation is not inherited from either parent but occurs for the first time in the affected individual.

Timothy syndrome is extremely rare, with an estimated frequency of less than 1 in 1,000,000 births. It was first described in the medical literature by George E. Keating and Michael T. Splawski in 2004, and the condition was named after the first patient diagnosed with the syndrome.

More information about the genetic causes of Timothy syndrome can be found in scientific articles and resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed. Genetic testing for CACNA1C-related disorders, including Timothy syndrome, is available in specialized genetic testing centers.

Researchers and advocacy groups are actively working to better understand the causes of Timothy syndrome and develop new treatments. Clinical trials and research studies focused on the genetic and molecular basis of the condition are listed on websites such as ClinicalTrials.gov. In addition, support groups and parent advocacy organizations provide resources and support for individuals and families affected by Timothy syndrome.

Learn more about the gene associated with Timothy syndrome

Timothy syndrome is a rare genetic disorder that affects the heart’s electrical system. It is caused by mutations in a gene called CACNA1C. The CACNA1C gene provides instructions for making a protein that is essential for the normal regulation of calcium channels in the heart.

Calcium channels play a critical role in allowing the flow of calcium ions into the heart muscle cells, which is necessary for the heart to contract and pump blood effectively. Mutations in the CACNA1C gene result in altered calcium channel function, leading to abnormal electrical signals in the heart and causing the symptoms of Timothy syndrome.

Timothy syndrome was first described in 1991 by Dr. Mark S. Timothy and colleagues. Since then, further research has identified specific mutations in the CACNA1C gene that are associated with this condition. These mutations are rare, and their frequency in the general population is not well known.

There are currently no cures for Timothy syndrome, and treatment is focused on managing the symptoms. Medications may be used to control abnormal heart rhythms, and in some cases, surgery or cardiac devices may be necessary. Research is ongoing to better understand the underlying causes of Timothy syndrome and develop new treatments.

If you are a parent or caregiver of a child with Timothy syndrome, it is important to consult with healthcare professionals who specialize in this condition. They can provide you with additional information and resources to support you and your child.

If you are interested in learning more about Timothy syndrome and the CACNA1C gene, there are several resources available.

Inheritance

Timothy syndrome is a rare genetic disorder that is caused by alterations in a gene called CACNA1C. This gene is responsible for encoding a protein involved in the regulation of electrical signals in the heart.

There are two types of Timothy syndrome: Timothy syndrome type 1 (TS1) and Timothy syndrome type 2 (TS2). TS1 is associated with cardiac issues, while TS2 is associated with other disorders, such as autism spectrum disorder and intellectual disability.

The inheritance of Timothy syndrome is autosomal dominant, which means that a person only needs to inherit one altered copy of the CACNA1C gene from either parent to develop the condition. However, it is important to note that the vast majority of cases of Timothy syndrome occur sporadically, meaning that the altered gene occurs for the first time in the affected individual and is not inherited from a parent.

Because Timothy syndrome is a rare condition, there is limited information available about the frequency of its occurrence in the general population. However, studies have shown that mutations in the CACNA1C gene are also associated with other cardiac disorders, such as long QT syndrome and Brugada syndrome.

For individuals who have been diagnosed with Timothy syndrome or who have a family history of the condition, genetic testing can provide valuable information about the specific genetic alterations that are present. This information can help to inform treatment decisions and provide information about the likelihood of passing on the altered gene to future generations.

Prior to genetic testing, it is important for individuals and their families to seek out resources and support from advocacy and patient support organizations. These organizations can provide information about the condition, connect individuals with others who have been affected by Timothy syndrome, and provide access to clinical trials and research studies.
