MYBPC3 gene – Austra Health

The MYBPC3 gene, also known as the myosin-binding protein C, is a gene that encodes proteins involved in the regulation of muscles, specifically the cardiac muscles. Variants in this gene have been found to be associated with various cardiac conditions, including hypertrophic cardiomyopathy and dilated cardiomyopathy.

Resources for this gene can be found in various databases and scientific articles. The MYBPC3 gene is listed in catalogs and databases such as PubMed, OMIM, and Genet. These resources provide information on the gene’s function, related conditions, testing methods, and additional references.

Studies have shown that mutations in the MYBPC3 gene can lead to hypertrophic cardiomyopathy, a condition characterized by an abnormal thickening of the heart’s muscle walls. This condition can cause symptoms such as shortness of breath, chest pain, and fatigue. Other related conditions, such as dilated cardiomyopathy and left ventricular noncompaction, have also been associated with mutations in this gene.

Further research is being conducted to better understand the role of the MYBPC3 gene in cardiac health and to develop better diagnostic tests and treatment options for individuals with related diseases. As more information becomes available, it is important for healthcare professionals and individuals to stay updated on the latest findings and recommendations.

Health Conditions Related to Genetic Changes

Genetic changes in the MYBPC3 gene have been found to be associated with several health conditions. These changes can lead to the development of various cardiac diseases, including hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM), and noncompaction cardiomyopathy.

Hypertrophic cardiomyopathy (HCM) is a condition characterized by the thickening of the heart muscle, specifically the ventricular walls. It is one of the most common inherited cardiac diseases and can lead to various symptoms, including chest pain, shortness of breath, and abnormal heart rhythms. Mutations in the MYBPC3 gene have been identified as a common cause of familial HCM.

Dilated cardiomyopathy (DCM) is a condition in which the heart becomes enlarged and weakened, leading to impaired pumping ability. Mutations in the MYBPC3 gene, along with other genes involved in cardiac muscle proteins such as myosin-binding protein C (MYBP-C), have been associated with DCM.

Noncompaction cardiomyopathy is a rare condition characterized by the prominent trabeculae (spongy appearance) in the ventricular walls. Genetic changes in the MYBPC3 gene have also been implicated in the development of this condition.

Information on these genetic changes and associated health conditions can be found in various scientific databases and resources. The Online Mendelian Inheritance in Man (OMIM) database provides detailed information on genetic disorders and is a valuable resource for exploring the role of the MYBPC3 gene in cardiac diseases.

The ClinGen database and the Genetic Testing Registry (GTR) also provide resources on genetic tests and their interpretations, including those related to MYBPC3 gene changes.

Additional scientific articles and references related to MYBPC3 gene changes and their connection to cardiac diseases can be found in PubMed, a comprehensive database of biomedical literature.

In conclusion, genetic changes in the MYBPC3 gene can lead to various health conditions, particularly hypertrophic cardiomyopathy, dilated cardiomyopathy, and noncompaction cardiomyopathy. The MYBPC3 gene is just one of many genes associated with these conditions, and further research is needed to fully understand the genetic basis of these diseases.

Familial hypertrophic cardiomyopathy

Familial hypertrophic cardiomyopathy (FHC) is a genetic disorder characterized by abnormal thickening of the heart muscle (hypertrophy), most commonly affecting the left ventricle. It is caused by mutations in the MYBPC3 gene, which encodes the myosin-binding protein C (MyBP-C) found in the cardiac muscles.

FHC is inherited in an autosomal dominant manner, which means that an affected individual has a 50% chance of passing the condition on to each of their children. The severity and age of onset of FHC can vary widely, even among affected individuals within the same family.

Clinical diagnosis of FHC is based on various criteria, including the presence of unexplained left ventricular hypertrophy (LVH), family history of FHC or sudden cardiac death (SCD), and the absence of other conditions that could cause LVH. Additional tests, such as echocardiography, genetic testing, and cardiac imaging, are often used to confirm the diagnosis and assess the severity of the condition.

The MYBPC3 gene is just one of many genes associated with familial hypertrophic cardiomyopathy. Mutations in other genes, including MYH7, TNNT2, TNNI3, and ACTC1, have also been found to cause FHC. Genetic testing for these genes may be helpful in identifying the underlying genetic cause of FHC in affected individuals.

There are several resources available for further information on familial hypertrophic cardiomyopathy and related conditions. The Online Mendelian Inheritance in Man (OMIM) database and scientific articles in PubMed are valuable sources of information on the genetics, clinical features, and management of FHC. The Familial Cardiomyopathy Registry and other cardiovascular genetics databases catalog information on genetic variants and the associated phenotypes in FHC and other related diseases.

In conclusion, familial hypertrophic cardiomyopathy is a genetic condition characterized by thickening of the heart muscle. Mutations in the MYBPC3 gene and other genes have been associated with this condition. Clinical and genetic testing can help diagnose FHC and guide treatment decisions. Understanding the underlying genetic changes in FHC can have important implications for the management of affected individuals and their families.

Left ventricular noncompaction

Left ventricular noncompaction (LVNC), also known as “spongy myocardium” or “noncompaction cardiomyopathy,” is a rare genetic disorder characterized by prominent trabeculations (spongy-like muscles) on the inner surface of the left ventricle. It can lead to various cardiac complications such as heart failure, arrhythmias, and blood clot formation.

The MYBPC3 gene, which encodes the myosin-binding protein C, is one of the genes known to be associated with LVNC. Variants in this gene have been found in both familial and non-familial cases of LVNC. Other genes involved in LVNC include those encoding cardiac contractile proteins such as myosin and thin filament proteins. Genetic testing can be done to identify any pathogenic variants in these genes.

LVNC can also be associated with other cardiac conditions, including hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM). In fact, the MYBPC3 gene is more commonly associated with HCM, another genetic disorder characterized by thickening of the heart muscle.

Left ventricular noncompaction has been documented in various scientific articles and has been listed in genetic databases such as OMIM. Extensive studies and research have been conducted to understand the pathophysiology, clinical presentation, and management of LVNC.

Familial dilated cardiomyopathy

Familial dilated cardiomyopathy is a genetic disorder that affects the heart muscle, causing it to become enlarged and weakened. It is one of the most common inherited heart diseases, with mutations in the MYBPC3 gene being a major cause of the condition.

Clinical features of familial dilated cardiomyopathy can include heart failure, arrhythmias, and sudden cardiac death. Diagnosis of the condition involves a thorough clinical evaluation, including family history, physical examination, and various tests such as echocardiography, electrocardiography, and genetic testing.

The MYBPC3 gene, located on chromosome 11, provides instructions for making a protein called myosin-binding protein C (MyBP-C). This protein is involved in the regulation of contraction and relaxation of the heart muscles. Mutations in the MYBPC3 gene can result in the production of a non-functional or abnormal MyBP-C protein, leading to the development of familial dilated cardiomyopathy.

Familial dilated cardiomyopathy can also be associated with other genetic conditions, such as hypertrophic cardiomyopathy and left ventricular noncompaction. These conditions may have overlapping clinical features and genetic mutations.

Resources for information on familial dilated cardiomyopathy and related conditions can be found in databases such as OMIM (Online Mendelian Inheritance in Man), PubMed, and various scientific journals and articles.

Genes associated with familial dilated cardiomyopathy:
Gene	Protein
MYBPC3	Myosin-binding protein C (MyBP-C)
Other genes	Various proteins

Additional testing, such as genetic testing for other genes associated with dilated cardiomyopathy, may be recommended to rule out other potential causes of the condition.

It is important for individuals with familial dilated cardiomyopathy to receive appropriate medical care and monitoring to help manage symptoms and prevent complications. Treatment options can include medications, lifestyle changes, and in severe cases, heart transplantation.
