Genetics in Medicine and Testing
Genetics in health care
Why medical genetics matters
Some diseases are caused by mutations in a single gene, while others involve many genes and environmental factors. Genetics can help explain disease risk, diagnosis, and treatment options.
Genetic testing
Genetic tests examine DNA, chromosomes, or related biological markers. They may be used to look for inherited conditions, carrier status, or specific mutations.
Important caution
A genetic result is not always a diagnosis by itself. Results should be interpreted carefully with a qualified professional.
Examples of uses
| Use | Purpose |
|---|---|
| Diagnosis | Identify a genetic cause of symptoms |
| Carrier screening | Check if someone carries a recessive mutation |
| Risk assessment | Estimate likelihood of future disease |
What can genetic testing examine?
Genetic tests often analyze DNA or chromosomes.
Correct answer: DNA
What is carrier screening?
A carrier may not show symptoms but can pass the variant to offspring.
Correct answer: Testing to see whether someone carries a recessive mutation
Why should genetic results be interpreted carefully?
Results often need context from family history, symptoms, and professional guidance.
Correct answer: Because a result may not tell the whole story
Name one medical use of genetics.
Genetics is widely used in several areas of medicine.
Correct answer: Diagnosis, carrier screening, or risk assessment
