Familial hypertrophic cardiomyopathy (FHC) is a genetic condition that causes thickening of the heart muscles, leading to impaired heart function. It is one of the most common inherited heart diseases, affecting more people than previously thought. The condition occurs in individuals with a family history of the disease, often passed down through multiple generations.
Scientific research on FHC has provided valuable information about its causes, inheritance patterns, and associated genes. Mutations in certain genes, such as MYH7, MYBPC3, and TNNT2, have been found to be responsible for the thickening of the heart muscles. Additional genes and mutations associated with FHC are continuously being discovered.
People with FHC may experience symptoms such as chest pain, shortness of breath, fatigue, and palpitations. The severity of symptoms can vary widely, even among affected family members. Regular cardiac testing, including echocardiograms and genetic testing, is recommended for individuals with a family history of FHC.
There are many resources available for individuals and families affected by FHC. The Genetic and Rare Diseases Information Center (GARD), OMIM, and PubMed are valuable sources of information on the condition and its genetic causes. Advocacy organizations, such as the Hypertrophic Cardiomyopathy Association, provide support and resources to help individuals and families navigate the challenges associated with FHC.
ClinicalTrials.gov is a useful tool for finding ongoing research studies and clinical trials related to FHC. These studies aim to improve understanding of the condition and develop more effective treatments. Researchers are also investigating the role of physical exertion and exercise in managing FHC.
In conclusion, familial hypertrophic cardiomyopathy is a genetic condition characterized by thickening of the heart muscles. It is associated with mutations in certain genes and occurs in individuals with a family history of the disease. Regular cardiac testing and access to resources and support are important for individuals and families affected by FHC.

Frequency
Familial hypertrophic cardiomyopathy (HCM) is a rare genetic condition that affects the heart muscle. It is characterized by an abnormal thickening (hypertrophy) of the heart muscle, which can interfere with the normal functioning of the heart. HCM is caused by mutations in certain genes that are involved in the contraction and relaxation of the heart muscle.
The frequency of HCM varies among different populations. Studies have shown that the condition affects approximately 1 in 500 people in the general population. However, the frequency can be higher in certain populations with a history of the condition, such as those of European or African descent.
There are several genes associated with familial HCM. Mutations in these genes can lead to the development of the condition. Some of the genes commonly associated with HCM include MYH7, MYBPC3, TNNT2, and TNNI3. Mutations in these genes can cause abnormalities in the proteins involved in the contraction of the heart muscle.
Testing for familial HCM can be done using genetic testing techniques. This involves analyzing the genes associated with the condition to identify any mutations. Genetic testing can help confirm a diagnosis and provide information about the inheritance pattern of the condition within a family.
Additional information about the frequency of familial HCM can be found in scientific articles and resources such as PubMed, OMIM (Online Mendelian Inheritance in Man), and the Genetic and Rare Diseases Information Center (GARD). These resources provide information about the condition, its genetic causes, and associated genes.
In summary, familial hypertrophic cardiomyopathy is a rare condition that is caused by mutations in certain genes involved in heart muscle contraction. The condition affects approximately 1 in 500 people in the general population, with higher frequencies in certain populations. Genetic testing can be used to confirm the diagnosis and provide information about the inheritance pattern of the condition.
Causes
Familial hypertrophic cardiomyopathy (HCM) is a genetic condition characterized by the abnormal thickening (hypertrophy) of the heart muscle. It is primarily caused by mutations in certain genes that are involved in the normal structure and function of the heart muscle.
There are several genes that have been identified as potential causes of familial HCM, including MYH7, MYBPC3, TNNT2, and TNNI3. Mutations in these genes can disrupt the normal contraction and relaxation of the heart muscle, leading to the development of hypertrophy.
Individuals with familial HCM often have a family history of the condition, although it can also occur sporadically without any known family history. Genetic testing is available to identify mutations in these genes, allowing for the diagnosis of familial HCM in individuals with a suspected or confirmed family history of the condition.
In rare cases, familial HCM can also be caused by mutations in other genes, such as ACTC1, MYL2, and MYL3. These genes are less common causes of the condition, but they have been identified in some individuals with familial HCM.
Research on the genetics of familial HCM is ongoing, and new genes and mutations continue to be discovered. It is important for individuals with a diagnosis of familial HCM to stay informed about the latest research and genetic testing options.

Genetic testing can provide valuable information about the specific genes associated with FHCM. These genes play a crucial role in the physical structure and functioning of proteins in the heart.
Some of the genes commonly associated with FHCM include:
- MYH7 gene
- MYBPC3 gene
- TNNI3 gene
- TNNC1 gene
- TNNC2 gene
- TNNT2 gene
- ACTC1 gene

- MYL3 gene
The inheritance pattern of FHCM can vary depending on the gene involved. Some genes are inherited in an autosomal dominant manner, while others follow an autosomal recessive pattern.
Research on the genes associated with FHCM and their specific mutations is ongoing. ClinicalTrials.gov provides information about current research studies and clinical trials focused on FHCM and related genetic diseases.
Additional resources and support can be found through organizations such as the Cardiovascular Genetics Center and advocacy groups. These organizations offer information, patient support, and resources for individuals and families affected by FHCM and related conditions.

Genetic testing can help identify the specific gene mutations involved in FHCM. This testing can provide essential information for diagnosis, prognosis, and treatment planning.
It is important to note that FHCM is a relatively rare condition, and genetic testing may not be available or necessary for all individuals. However, for those with a family history of the condition or symptoms associated with hypertrophic cardiomyopathy, genetic testing can be a valuable tool.
Learning more about the genes associated with FHCM can contribute to a better understanding of the condition and may lead to advancements in research, diagnosis, and treatment options.
Inheritance
Familial hypertrophic cardiomyopathy (FHC) is a genetic condition that is inherited in an autosomal dominant pattern. This means that a person with the disease has a 50% chance of passing the mutated gene onto each of their children.
This condition can occur in families with no prior history of heart disease, but it is also common for multiple family members to be affected. The disease can be caused by mutations in several different genes, including MYH7, MYBPC3, TNNT2, and others.
In recent years, research has supported the idea that mutations in genes encoding sarcomere proteins, which are responsible for muscle contractions in the heart, are more often associated with familial hypertrophic cardiomyopathy.
Testing for familial hypertrophic cardiomyopathy can be done through genetic testing, which can identify mutations in these genes. It is important to note that these mutations are rare and not all individuals with familial hypertrophic cardiomyopathy will have a detectable mutation. It is also possible for a person to have the disease without any known mutations in these genes.
Additional studies on the genetics of familial hypertrophic cardiomyopathy have shown that the disease can also be caused by mutations in genes that are not directly related to sarcomere proteins.
Physical exams, imaging tests, and family history can also help to diagnose familial hypertrophic cardiomyopathy. Patients with this condition typically have an increased thickness of the heart muscle, known as hypertrophy.
For more information on the genetics and inheritance of familial hypertrophic cardiomyopathy, there are several resources available including scientific articles, online databases like OMIM, patient advocacy groups, and clinical trial registries like ClinicalTrials.gov.
