Genetic profiling for risk reduction in human cardiovascular disease

Area of Science:

• Genetics
• Cardiology
• Genomics

Background:

• Cardiovascular diseases (CVDs) affect millions, with significant heritable components.
• Familial aggregation and twin studies confirm genetic influence on conditions like heart failure and cardiomyopathy.
• Genome-wide association studies (GWAS) have identified key genes and variants in CVD pathogenesis.

Purpose of the Study:

• To provide an overview of how genomic data is transforming the understanding and treatment of cardiovascular disease.
• To highlight the role of genetic variation in inherited cardiovascular conditions.
• To discuss advancements in genetic diagnosis for cardiomyopathy.

Main Methods:

• Review of familial aggregation, twin studies, GWAS, and next-generation sequencing (NGS) in cardiovascular genetics.
• Discussion of gene panels and broader exome/genome sequencing for cardiomyopathy diagnosis.
• Analysis of the impact of genomic data on clinical outcomes and therapeutic strategies.

Main Results:

• Genetic variations play a crucial role in the pathogenesis of various cardiovascular diseases.
• Current genetic testing for cardiomyopathy using gene panels has limited sensitivity (approx. 50%).
• Broader genomic sequencing approaches are increasingly used for more comprehensive genetic diagnosis.

Conclusions:

• Genomic data is revolutionizing the diagnosis and management of cardiovascular diseases, particularly cardiomyopathy.
• Genetic mutations identified through genomic sequencing can predict clinical outcomes, such as arrhythmia risk.
• Early genetic diagnosis facilitates timely therapeutic interventions, improving patient care.
