Genetics of coronary heart disease with reference to ApoAI-CIII-AIV gene region

Area of Science:

• Genetics and Molecular Biology
• Cardiology
• Population Health

Background:

• Cardiovascular diseases (CVDs) result from complex interactions between genetic and environmental factors.
• Twin and familial studies indicate a genetic predisposition to CVDs, with varying prevalence across ethnic groups.
• Advancements in molecular techniques and genetic markers aid in understanding CVD physiology and identifying susceptibility genes.

Purpose of the Study:

• To review the current understanding of genetic factors contributing to coronary artery disease (CAD) susceptibility.
• To highlight the role of specific candidate genes and their pathways in CAD.
• To discuss findings from genome-wide association studies (GWAS) identifying novel CAD-associated genes.

Main Methods:

• Literature review of genetic studies on cardiovascular diseases and coronary artery disease.
• Analysis of evidence from twin studies, familial aggregation, and ethnic population differences.
• Examination of molecular markers and candidate gene studies.
• Inclusion of findings from genome-wide association studies (GWAS).

Main Results:

• Multiple genes contribute to CAD predisposition, but findings are often inconsistent.
• Candidate gene studies suggest correlations with various CAD-related pathways.
• GWAS have identified novel chromosomal locations and genes associated with CAD.
• The ApoAI-CIII-AIV gene cluster is a focus of investigation for its role in CAD.

Conclusions:

• Genetic susceptibility plays a crucial role in the development of cardiovascular diseases, particularly CAD.
• Understanding the contribution of specific genes and gene clusters is essential for elucidating CAD etiology.
• Further research is needed to reconcile inconsistent findings and validate novel genetic associations for CAD.
