Summary
Gene-environment interactions influence cardiovascular disease risk. Understanding these links can reveal new pathways and improve personalized medicine for cardiometabolic diseases.
Area of Science:
- Cardiovascular Science
- Genetics
- Environmental Health
Background:
- Gene-environment interactions (GEI) are crucial for understanding cardiovascular disease (CVD) and cardiometabolic diseases.
- Previous studies indicate environmental/behavioral factors modify genetic risks for CVD, lipid traits, diabetes, obesity, and hypertension.
- Many observed GEI require replication, and underlying mechanisms and clinical impact need further investigation.
Purpose of the Study:
- To review current evidence on gene-environment interactions in cardiometabolic diseases.
- To identify knowledge gaps and future research directions.
- To assess the potential clinical utility of understanding GEI in CVD.
Main Methods:
- Literature review of studies investigating gene-environment interactions in cardiometabolic diseases.
- Synthesis of evidence on observed interactions and their consistency.
- Analysis of research needs for mechanistic and clinical impact studies.
Main Results:
- Several gene-environment interactions influencing cardiometabolic risk have been identified.
- Consistency of findings varies, with many requiring further replication.
- Mechanistic understanding and clinical implications of these interactions are largely underexplored.
Conclusions:
- Gene-environment interactions play a significant role in cardiometabolic disease development.
- Further research is essential to validate findings, elucidate mechanisms, and determine clinical applicability.
- Harnessing knowledge of GEI could lead to improved CVD risk prediction and prevention strategies.

01:20Gene-Environment Interactions
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...
02:27Background and Environment Affect Phenotype
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

01:27Psychoneuroimmunology: Cardiovascular Disease
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

01:23Behavioral Genetics and Its Designs
Behavior genetics explores how genetic inheritance influences human behavior. It focuses on how genes, passed from parents to offspring, contribute to the development of behavioral traits and tendencies. This branch of genetics seeks to understand the complex interplay between inherited genetic factors and environmental influences in shaping our behaviors.
The primary methodologies used in behavior genetics include family studies, twin studies, and adoption studies, each providing unique...

01:11Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
