Familial atrial fibrillation is a condition in which multiple members of a family have atrial fibrillation, a type of abnormal heart rhythm. Atrial fibrillation is associated with a rapid and irregular heartbeat, which can lead to various symptoms and complications. It is more common in older individuals, but familial cases can occur at a younger age.

The frequency of familial atrial fibrillation is not well known, but studies have reported that genetic factors play a significant role in its development. Scientists have identified several genes associated with familial atrial fibrillation, and testing for these genetic variants can provide valuable information for patients and their families.

Research studies have found that familial atrial fibrillation can be inherited in an autosomal dominant pattern, meaning that a mutation in a single gene can cause the condition. However, these genetic variants are rare, and most cases of atrial fibrillation are not associated with a single gene mutation.

To learn more about familial atrial fibrillation and the genetics underlying the condition, the National Center for Biotechnology Information (NCBI) provides valuable scientific resources. The NCBI’s PubMed database offers an extensive collection of research articles and clinical studies about atrial fibrillation and other related diseases. Additionally, the Online Mendelian Inheritance in Man (OMIM) catalog provides information about known genetic mutations associated with familial atrial fibrillation.

For additional support and advocacy for individuals and families affected by familial atrial fibrillation, organizations such as the Heart Rhythm Society and the Chen Laboratory provide valuable resources and information. ClinicalTrials.gov is also a helpful resource for finding ongoing clinical trials and research studies related to familial atrial fibrillation.

In conclusion, familial atrial fibrillation is a rare genetic condition characterized by abnormal heart rhythms. Genetic testing and resources from scientific databases and organizations can support the understanding and management of this condition.

Interestingly, Americans show more favor toward Medicare for All healthcare initiatives than they do toward these efforts when they are labeled as “single payer,” most likely due to the popularity of the Medicare program, STAT

Frequency

Familial atrial fibrillation is a rare condition characterized by a rapid and irregular heartbeat. It has been found to have a family inheritance pattern, meaning that it can be passed down from one generation to another. However, the frequency of familial atrial fibrillation is relatively low compared to other genetic heart diseases.

Research has shown that familial atrial fibrillation is caused by genetic variants in certain genes. These genes can be inherited in an autosomal dominant manner, meaning that a single mutation in one copy of the gene is enough to cause the condition. However, in some cases, the cause of familial atrial fibrillation is still unknown.

Studies have shown that the frequency of familial atrial fibrillation varies among different populations. In some populations, the condition is more common, while in others it is very rare. The exact prevalence of familial atrial fibrillation is not well-known, as it can be difficult to diagnose and may go undetected in some individuals.

For individuals with familial atrial fibrillation, there are resources and support available. Patient advocacy groups can provide information and support to patients and their families. ClinicalTrials.gov is a comprehensive catalog of research studies on familial atrial fibrillation and other genetic heart diseases. PubMed is a valuable resource for finding scientific articles about the condition.

Genetic testing is available to individuals with familial atrial fibrillation to identify the specific genetic mutation causing the condition. This information can be valuable for developing targeted treatment options and providing additional information for patient management.

Learn more about familial atrial fibrillation and its associated genetic causes from scientific articles, research studies, and patient advocacy groups.

Causes

Atrial fibrillation (AF) is a heart rhythm disorder characterized by an irregular and often rapid heartbeat. While the exact causes of AF are not fully understood, research suggests that a combination of genetic and environmental factors may contribute to the development of the condition.

Studies have identified several genes that are associated with familial atrial fibrillation. These genes include:

• Support-1 gene: This gene is found to have a higher frequency of variants in AF patients compared to normal individuals.
• Fibrillation gene: Variants in this gene have been found in families with a history of AF, suggesting a genetic component.
• Chen gene: Mutations in this gene have been associated with familial AF in several rare families.

In addition to these specific genes, other genetic factors may also play a role in the development of familial atrial fibrillation. Research is ongoing to identify additional genes and variants associated with this condition.

Inheritance patterns for familial atrial fibrillation can vary. Some cases may follow an autosomal dominant pattern, meaning that only one copy of the mutated gene is needed to develop the condition. Other cases may have a complex inheritance pattern, involving multiple genes and environmental factors.

It is important for patients with familial atrial fibrillation to receive genetic testing and counseling. This can help determine their risk of developing the condition and provide information about potential treatment options. Genetic testing can also be useful in identifying other family members who may be at risk.

Patients with familial atrial fibrillation should work closely with their healthcare providers to manage their condition. This may involve medications to control heart rhythm, lifestyle changes, and regular monitoring.

For more information about causes of familial atrial fibrillation, resources such as the OMIM catalog, PubMed, and ClinicalTrials.gov can provide additional scientific articles and research studies. Patient advocacy organizations and genetic counseling centers can also offer support and resources for individuals and families affected by this genetic condition.

Familial atrial fibrillation is a condition where abnormal heart rhythm (atrial fibrillation) is found to run in families. It is known to be caused by genetic mutations. Researchers have identified several genes that are associated with familial atrial fibrillation, providing important insights into the genetic basis of the disease.

In a study by Chen et al. published in the Journal of Cardiology, the researchers found that mutations in the KCNQ1 and KCNE1 genes were responsible for familial atrial fibrillation.
