Genetics, epigenetics and disease

Area of Science:

• Genetics and Epigenetics
• Environmental Health
• Nursing Science

Background:

• The Human Genome Project's promise to cure genetic diseases remains unfulfilled.
• Gene function is more complex than simple on/off switches, involving intricate gene-environment interactions.
• Growing evidence highlights the impact of environmental stressors on genetic expression throughout life.

Purpose of the Study:

• To underscore the importance of understanding gene-environment interactions for health.
• To emphasize the evolving role of nurses in genetic counseling and education.
• To prepare nurses for discussions on new genetic and epigenetic technologies.

Main Methods:

• Review of current research and theories in genetics and epigenetics.
• Analysis of the impact of environmental stressors on genetic expression.
• Discussion of emerging genetic technologies and their implications.

Main Results:

• Environmental exposures (physical, nutritional, emotional) before and during life measurably affect genetic expression.
• Individual genotyping and genetic engineering are becoming more accessible.
• Understanding genetics and epigenetics is crucial for assessing health risks and managing diseases.

Conclusions:

• Nurses require updated knowledge of genetics and epigenetics to provide effective patient care.
• Prenatal and preconception counseling on nutrition and lifestyle is a vital nursing function.
• Nurses must be equipped to discuss the ethical and safety aspects of genetic technologies.
