Insights
Dilated cardiomyopathy (DCM) is the most common heart muscle disease, often caused by genetic mutations. This review explores the diverse genes and cellular pathways involved in DCM
Area of Science:
- Cardiology
- Genetics
- Molecular Biology
Background:
- Cardiomyopathies are diverse heart muscle diseases with a known genetic basis.
- Dilated cardiomyopathy (DCM) is the most prevalent form, marked by ventricular dilation and impaired systolic function.
Purpose of the Study:
- To review major genes implicated in DCM.
- To focus on the pathophysiologic mechanisms underlying DCM.
- To highlight recent discoveries in DCM research.
Main Methods:
- Literature review of genetic mutations in DCM.
- Analysis of cellular pathways involved in DCM pathogenesis.
- Synthesis of recent scientific findings on DCM.
Main Results:
- Over 40 genes associated with DCM have been identified.
- Mutations affect proteins in various cellular structures and pathways.
- Diverse pathophysiologic mechanisms contribute to DCM development.
Conclusions:
- Genetic factors play a crucial role in DCM.
- Understanding affected pathways is key to DCM pathogenesis.
- Ongoing research continues to uncover new insights into DCM.
Abstract:
Cardiomyopathies represent a wide and heterogeneous group of diseases wherein a genetic cause has been consistently identified.Dilated cardiomyopathy (DCM) is characterized by ventricular dilation and progressive systolic dysfunction, and it is the most common form of cardiomyopathy.Causative genetic mutations have been identified in more than 40 genes encoding proteins belonging to different cellular structures and pathways.A great diversity of pathways has been implied in the pathogenesis of DCM, depending on the affected genes and on the dislodged intracellular structures or mechanisms.This review describes the major genes and focus on the pathophysiologic mechanisms of DCM, with a special consideration of the most recent discoveries in the field.
