Many conditions and diseases are related to genes in some way. Some mutations may be in a single gene, although most disorders are more complex. Many diseases, such as heart disease and diabetes, are caused by issues with multiple genes in combination with lifestyle and environmental factors.

How does genetics and environment affect health?
Subtle differences in one person’s genes can cause them to respond differently to the same environmental exposure as another person. As a result, some people may develop a disease after being exposed to something in the environment while others may not.
How do genetic factors affect individuals and public health?
Risks for almost all human diseases result from the interactions between inherited gene variants and environmental factors, including chemical, physical, and infectious agents and behavioral or nutritional factors, raising the possibility of targeting disease prevention and health promotion efforts to individuals at …

What are the benefits of genetics to health and public health?
The convergence of public health and genetics holds the possibility of improved understanding of the etiology, prevention, and management of complex diseases such as diabetes, dementia, heart disease, cancer including oral cancers, dental diseases, and syndromes.
Why are genes so important to human development?
Genes are the building blocks of life. They contain information for making specific molecules and proteins that allow human cells to function and that control how the body grows and operates. They also lead to the expression of particular physical characteristics and traits like hair or eye color.
How do genetics influence human Behaviour?
Genes influence each individual’s behavioral and psychological characteristics, including intellectual ability, personality, and risk for mental illness—all of which have bearing on both parents and children within a family.

How do genes cause disease?
By changing a gene’s instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all. When a variant alters a protein that plays a critical role in the body, it can disrupt normal development or cause a health condition.
What is a genetic based health issue?
Genetic disorders occur when a mutation affects your genes or chromosomes. Some disorders cause symptoms at birth, while others develop over time. Genetic testing can help you learn more about the likelihood of experiencing a genetic disorder.
What role can genes play in medicine?

How can genetics help to prevent diseases?
Using DNA genetic testing methods to find underlying diseases. Genetic testing provides a detailed analysis of a person’s DNA. The promise of genetic testing lies in its ability to reveal gene mutations, or changes in your genetic makeup, that may cause disease.
What genes do biologically?
Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
What are genetic influences?
Genetic influences operate at two levels: one is the genetic predisposition to certain diseases, and the other is the genetic determination of disease. From: International Encyclopedia of the Social & Behavioral Sciences, 2001.
