DES gene, also known as desmin gene, is responsible for the production of a protein called desmin. Desmin is primarily found in the myofibrils, which are the contractile units of muscle cells. It provides structural support and helps to maintain the integrity of muscle fibers.
The DES gene is associated with various diseases and conditions, including myofibrillar myopathy and dilated cardiomyopathy. In myofibrillar myopathy, mutations in the DES gene cause a breakdown of the myofibrils, leading to muscle weakness and dysfunction. Dilated cardiomyopathy, on the other hand, is a condition characterized by the enlargement of the heart chambers and impaired heart function, often caused by mutations in the DES gene.
References to studies and scientific articles on DES gene and its variants can be found in databases such as PubMed and OMIM. These resources provide additional information on the genetic cause, clinical features, and testing methods for diseases associated with DES gene mutations. The DES gene is included in genetic testing panels and registries for myopathy and dilated cardiomyopathy, offering diagnostic and predictive testing for individuals with symptoms or a family history of these conditions.
In conclusion, the DES gene plays a crucial role in the health and function of muscles, particularly in the myofibrils. Mutations in this gene can lead to various muscle disorders, including myofibrillar myopathy and dilated cardiomyopathy. Scientific articles, databases, and testing resources provide valuable information for researchers, clinicians, and individuals seeking to understand and manage these conditions.
Health Conditions Related to Genetic Changes
Genetic changes in the DES gene have been associated with several health conditions, including:
- Dilated cardiomyopathy (DCM): This condition is characterized by weakness in the heart muscles, leading to an enlarged and weakened heart. It can cause symptoms such as shortness of breath, fatigue, and irregular heartbeat.
- Arrhythmogenic right ventricular cardiomyopathy (ARVC): A disorder that affects the muscles of the right ventricle of the heart, causing abnormal heart rhythms and an increased risk of sudden cardiac death.

Myofibrillar myopathy
Myofibrillar myopathy (MFM) is a genetic disorder that affects the muscles. It is caused by mutations in various genes, including the DES gene.
The DES gene, which stands for desmin, is responsible for providing instructions to produce a protein called desmin. Desmin is an essential component of myofibrils, which are the structural units of muscle cells. Mutations in the DES gene can lead to the formation of abnormal desmin protein, disrupting the organization and function of myofibrils.
MFM is listed in the Online Mendelian Inheritance in Man (OMIM) database, which provides information about genetic disorders. The DES gene is one of the genes associated with familial forms of myofibrillar myopathy.
Genetic testing can be done to identify mutations in the DES gene and other genes associated with myofibrillar myopathy. These tests can help in confirming the diagnosis of MFM and determining the specific genetic cause of the disease.
Scientific articles and publications in databases like PubMed can provide additional information about myofibrillar myopathy and related disorders. These resources can be helpful in understanding the genetic changes, clinical features, and management of the disease.
Myofibrillar myopathy is also known to be associated with arrhythmogenic right ventricular cardiomyopathy (ARVC). The Genetic Testing Registry (GTR) provides a catalog of genetic tests for ARVC and other related disorders, including MFM.
Testing for myofibrillar myopathy and related disorders can be done in specialized clinics and laboratories. It is important to consult a healthcare professional for proper testing and interpretation of results.

Arrhythmogenic right ventricular cardiomyopathy
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a genetic heart condition that affects the muscle tissue of the right ventricle of the heart. It is characterized by the replacement of normal heart muscle cells with fatty or fibrous tissue, which can lead to abnormal heart rhythms and, in some cases, heart failure.
ARVC has been linked to mutations in several genes, including the desmin gene (DES). DES gene mutations can cause a variety of heart conditions, including dilated cardiomyopathy and myofibrillar myopathy.
Genetic testing can be performed to identify mutations in the DES gene and other genes associated with ARVC. These tests can help confirm a diagnosis of ARVC and determine the specific genetic variant that is causing the condition.
In addition to genetic testing, other diagnostic tests such as electrocardiograms (ECGs), echocardiograms, and cardiac MRI scans may be used to evaluate the structure and function of the heart in people suspected of having ARVC.
ARVC is listed as a rare disease in several scientific databases and resources, including OMIM (Online Mendelian Inheritance in Man), ClinVar, and the NIH Genetic Testing Registry. These resources provide additional information on the genetic variants, clinical features, and management of ARVC.
Research articles and other scientific publications related to ARVC and the DES gene can be found in PubMed, a database of biomedical literature. These articles can provide further insights into the causes, symptoms, and treatment options for ARVC.
