Insights
Genetic testing for hypertrophic cardiomyopathy (HCM) is now essential for cardiologists. Understanding genetic links aids in diagnosing, predicting outcomes, and treating this common inherited heart condition.
Area of Science:
- Cardiology
- Genomics
- Medical Genetics
Background:
- Hypertrophic cardiomyopathy (HCM) is a prevalent inherited cardiovascular disease affecting ~1 in 500 individuals.
- HCM is a leading cause of sudden cardiac death, particularly in young athletes.
- Genomic medicine is increasingly integrated into clinical cardiology practice.
Purpose of the Study:
- To highlight the essential role of genetic testing in the clinical evaluation and management of hypertrophic cardiomyopathy.
- To underscore the importance of understanding diagnostic, prognostic, and therapeutic implications of genetic testing for HCM.
Main Methods:
- Extensive research over two decades investigating the pathogenic basis of HCM.
- Analysis of genotype-phenotype correlation studies.
- Review of the introduction and implications of commercially available genetic tests for HCM.
Main Results:
- Numerous HCM susceptibility genes have been identified.
- Growing data links specific genotypes to clinical phenotypes.
- Genetic testing for HCM is now a clinical reality.
Conclusions:
- Cardiologists must possess a comprehensive understanding of HCM genetic testing.
- Genetic insights are crucial for personalized diagnosis, prognosis, and treatment strategies in HCM patients.
Abstract:
Over the last 2 decades, the pathogenic basis for the most common heritable cardiovascular disease, hypertrophic cardiomyopathy (HCM), has been investigated extensively. Affecting approximately 1 in 500 individuals, HCM is the most common cause of sudden death in young athletes. In recent years, genomic medicine has been moving from the bench to the bedside throughout all medical disciplines including cardiology. Now, genomic medicine has entered clinical practice as it pertains to the evaluation and management of patients with HCM. The continuous research and discoveries of new HCM susceptibility genes, the growing amount of data from genotype-phenotype correlation studies, and the introduction of commercially available genetic tests for HCM make it essential that the modern-day cardiologist understand the diagnostic, prognostic, and therapeutic implications of HCM genetic testing.
