Genes influence many aspects of health, but they rarely tell the whole story. Explore their relationship with nutrition, body shape, disease risk and care designed around individual differences.
These articles examine associations between genetic variation and health. An association is not a diagnosis, and lifestyle, environment, age and medical history can all affect individual outcomes.
An observational study explored fish consumption among people with a genetic predisposition to obesity. Learn why this type of research can suggest a relationship without proving cause and effect.
How genetic and other health information may help researchers study differences in prevention and treatment.
Genes can contribute to where the body stores fat, while health risk also depends on a wider set of measurable factors.
Read the current collection, then discuss personal screening or testing questions with a qualified health professional who knows your history.
Headlines can make genetic influence sound fixed or definitive. A more careful reading asks what was measured, who participated and how large the observed effect was.
A variant may be associated with higher or lower risk without determining whether a person will develop a condition.
Environment, behavior, access to care, age and other biological factors may interact with inherited traits.
Testing can have medical and emotional implications. Clinical interpretation belongs with an appropriately qualified professional.
Brief answers to common questions about inherited traits, risk estimates and genetic information.
Usually not on their own. Many conditions reflect a combination of genetic, environmental, behavioral and age-related influences.
It means inherited variation may affect the likelihood of an outcome. It does not mean that outcome is inevitable.
Habits may influence overall risk for many conditions, but the effect differs by person and condition. Personalized guidance should consider your complete health history.
Not necessarily. Scope, methods and clinical relevance vary. Do not change treatment or screening based only on a consumer result.
It is an approach that studies how differences in genes, environment and lifestyle may inform prevention or treatment decisions.
Consider qualified guidance before testing, when interpreting a result, or when family history raises questions about screening and prevention.
