Genetic Evaluation and Screening in Cardiomyopathies: Opportunities and Challenges for Personalized Medicine

Area of Science:

• Cardiology
• Genetics
• Medical Diagnostics

Background:

• Cardiomyopathy, a leading cause of heart failure, stems from heart muscle abnormalities hindering blood circulation.
• Monogenic (single-gene) causes are increasingly recognized as significant etiologies of cardiomyopathy.
• Technological advancements necessitate understanding genetic underpinnings for patient and family education.

Purpose of the Study:

• To review clinical genetic testing approaches for various cardiomyopathies.
• To highlight the importance of early detection and personalized treatment strategies.
• To emphasize the value of family screening and genetic counseling.

Main Methods:

• Review of current literature on genetic testing for cardiomyopathies.
• Discussion of multidisciplinary approaches involving genetic counseling and clinical genetic testing.
• Exploration of strategies for identifying impactful genetic variants and managing variants of uncertain significance.

Main Results:

• Early identification of inherited cardiomyopathy facilitates timely initiation of guideline-directed medical therapies.
• Genetic screening enables cascade testing for at-risk family members through phenotype screening and risk stratification.
• Personalized treatment plans can be developed based on genetic evaluation.

Conclusions:

• A multidisciplinary approach to genetic screening, counseling, and testing is crucial for cardiomyopathy patients and families.
• Early detection and treatment based on genetic findings significantly improve patient prognoses and health outcomes.
• Managing genetic variants and implementing family screening are essential components of comprehensive cardiomyopathy care.
